Peanut Butter Stuffed Brownies*

Last year Jorge turned 29 and I made him Reece’s Pieces Cupcakes. Today is his 30th birthday and big surprise, he requested something with chocolate and peanut butter. In the past, we have had Chocolate Peanut Butter Pretzel Bites, Mini Peanut Butter Oreo Pies, Peanut Butter Stuffed Chocolate Cookies, Dark Chocolate Peanut Butter Banana Bites and Fluffernutter Cookies. To say the least, I was totally out of peanut butter & chocolate ideas. Well besides cake, but big layered cakes with gobs of frosting is much more my thing — not his.

So last week he came home from a bakery with a brownie the size of his head and it came to me. Peanut Butter Stuffed Brownies. That will totally rock his chocolate & peanut butter lovin’ world.

I made these babes in my individual square cake pan. They cook twice as fast and are easier to stack into a faux-cake to put candles on top of. 😉  …but really I did it because I am convinced the individual square brownies are just cuter.

Because of the peanut butter in the middle, these stay very moist and fudgey. I thought about adding chocolate chips to the batter, but I am so glad I didn’t. Because that would have been WAY too rich…even for the girl who has a sweet tooth the size of Texas.


Peanut Butter Stuffed Brownies

Yield: 16 Brownies


  • 1 cup flour
  • 2 tablespoons double dutch cocoa powder
  • 1 teaspoon instant espresso
  • 2 sticks butter
  • 6 oz (2 bars) scharffen berger extra dark 82% chocolate, chopped
  • 4 large eggs
  • 1 1/2 cups granulated sugar
  • 1/2 cup packed light brown sugar
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon salt
  • 3/4 cups peanut butter
  • 1 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 2 tablespoons milk


Preheat oven to 325°F. Grease individual square cake pan (or pan of choice).

In a small bowl, mix together flour, cocoa powder and instant espresso. Set aside.

In a double boiler, melt the butter and chopped chocolate. Let it melt over medium heat, stirring frequently until it is completely melted. Remove from heat and set aside for about 10 minutes to cool.

While chocolate is cooling, beat together peanut butter, powdered sugar, vanilla extract and milk in a stand mixer. Roll 1 tablespoon worth of peanut butter mixture into balls and flatten with hands into a 2 inch disk. Set aside.

In a large bowl, whisk the eggs, both sugars, vanilla and salt until smooth. Whisk in the cooled chocolate into the egg mixture, until combined. Beat in the flour in two additions, stirring until there are no large lumps left.

Fill each square half way with batter. Place a peanut butter disk in the center and cover the top with a little additional batter. Do not fill past 3/4 full.

Bake for 25-28 minutes, or until centers are set. Let cool for 15 minutes and then transfer to a cookie tray to cool completely. Store in an airtight container for up to 3 days.

    They look fabulous – PB stuffed in anything has a way of doing that :)

    And the individual square cake pan – was wondering what kind of results those produced. Clearly, GREAT results!

    Perfect Birthday treat! I have been thinking of doing something like this, but I don’t have the cute individual cake pans, so they wouldn’t be nearly as cute!

    Angelyn @ Everyday Desserts — July 30, 2012 @ 4:50 pm

    This is such a good idea. They look absolutely delicious!

    I am currently hiding my laptop from my boyfriend so he doesn’t see these and demand that I make them immediately. Because then I’d have to share.

    Happy Birthday Jorge!

    Oh, and Jessica, this is my biggest first world problem! How does one keep coming up with new and better ideas for the man’s birthday cake, for another man who also isn’t a huge fan of cake!?

    So far, he’s had a chocolate caramel tart, a tower of profiteroles, and a cannoli tower… and it’s his thirtieth birthday next year!! Takes months of planning and stressing over WHAT to bake.

    But good to see I’m not the only one…!

    These look delicious! It’s my daughter’s birthday tomorrow and she’s still debating what kind of cake she wants. I think I’m going to convince her we need these!

    Happy birthday (b-lated) to your husband Jorge! I’ve done something similar to this but baked the brownies in a cupcake pan instead. Oh, and since I love super rich treats I topped my peanut butter stuffed brownie cupcakes with a chocolate buttercream.
