Old Fashioned Iced Oatmeal Cookies are a homespun favorite, with a chewy, crunchy texture. Made with wholesome ingredients and topped with sweet icing, these easy cookies are too good to resist!
These are the ultimate lazy baker’s cookies! Based on a handwritten recipe from my Granny’s cookbooks, these are no-fuss, classic oatmeal cookies made with pantry basics. Even the simple icing has only two ingredients!
That being said, this easy oatmeal cookie recipe doesn’t skimp on texture or flavor. These old fashioned oatmeal cookies are all about texture; not too soft, not too crunchy, with just the right amount of irresistible chew.
I love to make a batch of these during the week to enjoy as a quick and easy sweet dessert or snack. They’re just right with a cup of coffee, a glass of ice-cold milk, or some sweet apple cider. Yum.
What You’ll Need
Here’s the list of ingredients you’ll need to achieve the perfect oatmeal cookie:
For the Cookies
- Old Fashioned Oats: Old fashioned or rolled oats are the best oats for oatmeal cookies. They bake into the best hearty texture!
- Butter: Unsalted is best. It should be melted. I do this in the microwave, melting it in short bursts of about 10 seconds and stirring after each burst. You could also melt it over low heat on the stovetop.
- Sugar: I use both light brown sugar and granulated sugar; the combination makes for an exceptionally perfect, slightly chewy cookie!
- Spices: Freshly ground cinnamon and nutmeg for just the right hint of warm spice.
- Eggs: I’ve found 2 whole large eggs result in the best-textured cookies.
- Flour: Plain all-purpose flour works perfectly in this recipe.
- Baking Powder and Baking Soda: Using both together gives the cookies a lift, so they aren’t hard or heavy.
- Salt: To bring out the flavor in the oats and spices.
For the Icing
- Powdered Sugar
- Milk
Can I Use Quick Oats Instead?
Technically, quick oats will work for this recipe in a pinch. However, since quick oats cook faster than rolled oats, the size and texture of the cookies will be less consistent. For this reason, and for the sake of a perfectly chewy cookie, I wouldn’t recommend it.
Making these cookies is practically a cakewalk! Or a cookie walk? Either way, it’s extremely easy, which is great for a busy cook. Here’s the process, step by step.
Mix the Dry Ingredients: To begin, coarsely grind the oats using a food processor. Combine the oatmeal with the rest of the dry ingredients: flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set this mixture aside for now.
Combine the Wet Ingredients: Cream together the melted butter and both sugars, and then beat in your eggs one at a time.
Prepare the Dough: Stir the wet and dry mixtures together, until everything is well-combined. Drop the dough by heaping tablespoons onto buttered cookie sheets, leaving a little space between each spoonful of dough.
Bake: Bake the old fashioned oatmeal cookies until they’re golden-brown, about 15 minutes. Let them rest on the baking sheets for a few minutes, and then transfer them to a wire rack to cool (a metal spatula is helpful for this).
Ice the Cookies: To make the icing, just whisk together the powdered sugar and milk until smooth. Generously top each cookie, and allow the frosting to set completely.
Enjoy! Serve immediately, or store for another time.
Tips and Tricks
Even a quick and easy recipe like this has its quirks, so be sure to check out these helpful tips for making the perfect oatmeal cookies. Here we go:
- Butter the Baking Sheet: To encourage the cookies to spread as they bake, don’t forget to butter your cookie sheet!
- Measure the Flour Correctly: Too much flour is one reason you’ll end up with overly cakey cookies. To avoid this, spoon the flour into a measuring cup and then level it off using a knife.
- Go for Thick Icing: The simple icing in this recipe should be somewhat thick, so that it will set up firm. If it’s too runny, it won’t set very well. So you can definitely add a bit more powdered sugar if it looks watered down!
Tasty Variations
Such a perfect, simple oatmeal cookie is the best base for add-ins and imagination. Kick the fall flavors up a notch with a sweet Maple Icing. You can also mix things up by adding some sweet mix-ins to your dough:
- Chocolate chips
- Dried cranberries
- Raisins
- Toffee bits
- Crushed nuts (macadamias, pecans, peanuts, almonds)
Oatmeal cookies that are stored properly will keep for up to 2 weeks at room temperature. Once the frosting on the cookies has hardened, store the cookies in an airtight container or resealable ziplock bag, away from sunlight.
Can I Freeze These?
You can freeze these oatmeal cookies for up to 3 months, wrapped tightly in plastic wrap or stored in an airtight freezer bag or container. Thaw at room temperature before serving.
Ingredients
For the Cookies:
- 2 cups old fashioned oats
- 2 cups all-purpose flour
- 1 tablespoon baking powder
- 1 teaspoon baking soda
- 2 teaspoons cinnamon
- 1 teaspoon freshly ground nutmeg
- 1 teaspoon salt
- 1 cup (2 sticks) unsalted butter, melted
- 1 cup granulated sugar
- ½ cup packed light brown sugar
- 2 large eggs
For the Icing:
- 2 cups powdered sugar
- 5 tablespoons milk
Instructions
- Preheat oven to 350°F and butter two cookie sheets. Set aside.
- In a food processor, pulse oats a few times until partly ground. You don’t want a fine powder, you want a coarse meal. Add in the flour, baking powder, baking soda, cinnamon, nutmeg and salt. Pulse 2 to 3 times just to combine and set aside.
- In a large bowl, beat together the melted butter, sugar and brown sugar. Add eggs, one at a time. Mix in the dry oat mixture, stirring until thoroughly combined.
- Drop dough by (heaping) rounded tablespoons onto prepared cookie sheets. Bake for 14 to 16 minutes, rotating halfway through, until browned. Let cookies rest on the baking sheets for 5 minutes before moving to a wire rack to cool completely.
- Once cookies are completely cooled, whisk together the powdered sugar and milk until smooth. Generously frost each cookie and allow the glaze to harden completely before storing. Store in an airtight container for up to a week.

Great rec., thx so much!!!
In you comments before the recipe was listed, you mentioned using a can of pumpkin puree. I did not see this listed as one of the ingredients in the actual recipe. Did I misunderstand for is there supposed to be pumpkin in these cookies. I plan to make them soon and want to make sure I have everything correct.
Hi. I just made these and I’m a bit confused about the dough. It came out soupy. I’m not entirely sure what happened. I added an extra cup of flour, and they are still soupy. Should I have put them in the fridge for a while before baking? Should I have used soft butter instead of melted?
Hmm. I wish I could know what you did so I could easily diagnose the problem…but I am not sure what happened. I know this recipe is a winner because it’s a top recipe on my site that people make all the time.
Between the 2 cups old fashioned oats and 2 cups all purpose flour, it definitely wouldn’t be soupy. The only liquid is eggs and some softened butter? Did you happen to add some other liquid?
Sorry I can’t be more help!
Thank you for the reply Jessica.
I’ve gone over what I did. The recipe calls for melted butter, not softened butter. Should I have used softened butter and not melted (liquid consistency)? I thought using melted butter may have been the culprit, but reading so many successes with this recipe, it couldn’t possibly be the cause for soupy dough. I really want to try it again, but a little worried about getting the same results. The eggs were at room temp and I used two large. Maybe I over processed the oats? I didn’t grind them down to a powder- maybe a 1/4 size of their original size.
I measured out 2 cups of oats and then processed them. Should I have measured out 2 cups after processing them? Thanks for the help. You’re wonderful!
Hi Jessica, I wanted to print these out so I could make them tomorrow and its giving me an error404. Wanted you to know. PS I am a HUGE Britney Spears fan too. I love her and all her music. :-)
These are nothing like Archway or Mother’s in taste, and not crisp despite following the recipe exactly and even baking the second batch a tad longer. Will be turning these into ice cream sandwiches ala It’s It.
I stumbled upon this recipe a couple of years ago…I honestly am asked for the recipe all the time! It is soooo good and loved by all!
Made these for a fund raiser. Sold out in less then 15 mins (had samples). I placed icing in a piping bag and zig zaged it over the tops. Yum, these are great.
These are the best oatmeal cookies i’ve ever had! Thank you so much!
I just finished icing the cookies! They are delicious! Thank you for an easy recipe.
Will they turn out just as good without cinnamon? I’m horribly allergic but love these cookies. :(
It will not have the same flavor, but the cookies will bake just fine with out it! Hope you enjoy them! :-)
This is so awesome. Now I don’t have to buy those Archway cookies anymore.
Um…awesome!! Loved it, came out perfect! I used heavy cream for the frosting. It was almost too hard to stir, but 10 seconds in the micro a couple of times made it come out perfect! Hardened up beautifully! Thanks so much for the recipe! It’s so great!!!
I found the frosting to be runny and it didn’t harden up. I was bummed…plus there were little nuggets of powdered sugar throughout no matter how long I stirred. Any tips or substitutions? Thanks! The cookies were delicious otherwise!
With just milk and powdered sugar, there shouldn’t have been any issues with it being lumpy. However, next time you can always sift the powdered sugar first just to be sure there are no lumps!
As for the consistency, you can always add less milk for a thicker frosting!
3 batches in 3 weeks! OMG these are Amazing.
I’m so excited to make these tonight! I was wondering does it matter what type of milk (as in nonfat, 1%, or 2%)? Thanks! Awesome pictures!!
I use whole milk while baking, but I think you would be fine with 2% as well! :)
The icing on these is very runny. Also, I find if you grease the pan they get burnt on the bottom. Anyone else have the same problems?
It does harden up if you let it sit, however feel free to add more powdered sugar to thicken it up!
Yum, just got mine glazed and they are delish! I didn’t read the instructions since I was watching Project Runway on another browser tab… oops! So I missed the ground oatmeal, but they taste great!
so glad you posted this recipe. It brought a smile to my face. These cookies bring up wonderful memories of my great grandmother. Even though she was an amazing baker, she always insisted on buying a bag of these treats for us because they knew we loved them! :) I don’t remember the brand, but remember they were bite size cookies sold in a blue bag.
OMG, these are soooooo delicious!!! Had to freeze some so I couldn’t keep eating them. Husband loved them too!!!
My Great Gran always had these in her cookie jar. Never really cared for them as a child but now I miss them (and Gran)! Can’t wait to make these=)
I loved the store-bought version of these when I was young, but I recently bought them and either my memory of them is not at all like reality OR they’ve gone down hlll in taste. Either way, I bet these cookies are the perfect solution.
Can’t wait to try them!
Plan to bake these soon! Mother’s iced oatmeal were always my favorite too! Thanks so much for sharing!!
Since there is milk in the frosting, do we need to store these in the refrigerator?
I didn’t store mine in the fridge, but they were all gone in under 2 days and my kitchen was cool. If you are worried, pop them in the fridge. :)
So delicious I had to blog about them :) http://hungryredhead.com/2012/12/18/old-fashioned-iced-oatmeal-cookies/
Can the dough be freezed and baked later somehow? These cookies were such a big hit in my house and we want to prepare the dough to make them for a cookie swap on Wednesday’! Thank you!!
I have done that with other cookie dough before, but I am not positive on how this cookie dough would do. It’s always worth a shot, but I can’t promise it will still create the same cookie.
I have made these cookies twice now and they are so, so, so fantastic! My coworkers loved them, too :)
Yay! Always glad to hear that they worked out great for someone else too!
Could you add raisins??
These aren’t a traditional oatmeal cookie, but sure if you want to!
Just what I always wanted!
These cookies look so good – chewy and thick, the best kind of oatmeal cookie in my opinion. Thanks for sharing the recipe!
I’ve made these two nights in a row now and they are amazing. Thanks for the recipe! I added a slight bit more cinnamon the second time though, just a tiny bit, just because I love the taste but the recipe as it’s written is amazing. Oh and I used cream for the icing as I didn’t have any milk in the house and it was great. Thanks!
Brit can totally sing!!!!!! haha. Such a fangirl.
But, most importantly, I LOVE iced oatmeal cookies and I’m so excited to make these! Thanks for the recipe! =)
I am so happy I found your blog on pinterest. As you migt see I am very addicted. :-) And by the way: When it comes to Britney I am also a girl of the 90’s. :-)
My parents always buy this kind of cookie from the grocery. I bet a homemade version is FANTASTIC!
I remember eating these as a kid and can’t wait to try this homemade version!!
Oh my gosh… I HAVE to make these for Mike – Iced Oatmeal cookies are his favorite! he will FLIP.
How can you not love Brit? The epitome of hawtness, with that slight edge of white trashiness. Loving her on the X Factor too!
Also, how could you not love these cookies? They look absolutely divine. But, light enough you could eat like 15! :)
So nostalgic :) My grandma used to have the Little Debbie kind at her house!
Sometimes nothing beats a glass of wine, a cookie, and judging celebrity clothing.
I made these wonderful cookies last night and wow were they a hit. They are EXACTLY like the packaged ones EXCEPT nothing artificial.
My girls loved them and they will become a favorite in our house.
I LOVE grinding the oatmeal. Going to try them gluten free for my dad.
One change: I did SMALL scoops of dough… so I got almost 4 dozen. Thanks for this great recipe.
I just made these today and they are fantastic! Thanks!
I made these over the weekend and they are spectacular!!! Thank You for bringing back memories from my childhood~
These look perfect!!!
These seriously have given me a case of nostalgia…YUM!! I need these in my life. Looking forward to meeting you tomorrow in Idaho!
LOVE the stack of oatmeal cookies! Looking forward to meeting you this Monday in Idaho :)
Mmm these sound lovely!
Yum! I’ve been looking for a proper sweet oatmeal cookie! Even if I can’t bring myself to watch X Factor.
And Jessica, if you’re a Lush girl, as I am- depending on your skin type of course, have you tried their Cosmetic Lad moisturiser? It’s my favourite, go to daily moisturiser!
So, I’m on my way over to kick up my feet with you, watch the XFactor and eat well over my fair share of these cookies! Because, you know, now I’m eating for TWO. ;)
I’m a big fan of nostalgia, and these cookies definitely take me back. I can’t wait to try them and have them stuck in my teeth.
Ahh! The best cookies ever!!
I totally love Britney too. And I don’t care who knows it!
Wow, I haven’t thought of these cookies in years but they are definitely one of my favorites. I love that I now have a recipe and won’t have to buy the store-bought version anymore.
These look so good! My husband loves the Mother’s cookies like this too, he would really love these!
I couldn’t even watch Britney, is she doing her own makeup?! Don’t they have hi definition powder?! Help a girl out, you know they have better products than what she is wearing. ;0)
I used to be addicted to these…along with Circus Animal cookies. The resulting sugar high, though, my mother was not quite a fan of. Guess I’m going to join your rebel cause and have to try my hand at these as well–thanks for sharing!
Love your rant on Britney — gotta remember to DVR xfactor.
And that’s a batch of cookie deliciousness!
What wonderful memories these cookies have brought back to me! Now I have a recipe to make them! I love your post! Thank you!
I love Britney too! I’ve seen her twice in concert and would go again in a minute. Her music makes me happy. Those cookies bring me back to childhood too. They sound so good!
I’m a girl of the 90’s too. No shame in loving Britney!! I might have to do the wine/cookie thing next time X Factor comes on…..sounds like a great plan to me!
Just took the first batch out of the oven …. OH.MY.GOODNESS!!
omg i love iced oatmeal cookies! i don’t watch x-factor but i will be making these. thanks!
I’m sure these were so tasty to gobble up while x factor was on!
These look heavenly. I didn’t love oatmeal cookies as a kid but not now I adore them!
Haha! My guilty pleasure lately has been Dawson’s Creek on Netflix! It usually involves wine but wine and cookies, oh please!, that is a routine I can get on board with! : ) Oh and my Mom would occasionally let us have the store bought iced oatmeal cookies when we were kids but homemade is always better!
I just wrote about Britney Spears the other day, too! I totally need to watch XFactor now. I also just made a fabulous oatmeal sandwich cookie (like Little Debbie!), but now I want frosted ones instead. Your photos are beautiful!
Love these! My grandma used to make these all the time!
These were one of my fav cookies growing up!
Oh man, how did you know these were the cookies I’d steal by the fistful from my grandma’s cabinets:??
So, I love that you made these cookies because they were my No. 1 favorite thing in the world growing up… but I also love that you have a wine fridge. I need to get me both of these things, stat! :)
These are bringing back all kinds of memories. I adore this post, Jessica. You are amazing!
Yum, these are gorgeous!
I think I might have to make these soon! I LOVED these cookies growing up and haven’t had them in years!
I just started watching x-factor for the first time this week and love it already. If only I had a batch of these cookies to enjoy with it!
Ohhh these look sooooo scrumptious! I haven’t seen Brit Brit on the X factor yet..I supose I need to watch it!
I’m LOVING Britney on XFactor. LOVING. She’s fantastic. I also love that you consider your wine when making a cookie selection.
