Chocolate Peanut Butter Brownies

I was thinking yesterday about recipes. I thought about brownies. I thought about peanut butter. I thought about chocolate. This really isn’t unusual, because I think about these things all the time. Using these three ingredients, I created this masterpiece of a recipe this afternoon. These Reese’s Chocolate Peanut Butter Brownies are homemade, thick, gooey brownies with rich peanut butter frosting on top. Top the bars with a few Reese’s Pieces and you have yourself a very sweet treat.

Fudgy Brownies

  1. First, make the brownies. It’s important to melt the sugar and butter together first, then add it to the other ingredients. This makes for perfectly fudgy brownies!
  2. Mix it up just until it is combined. Don’t overmix! Easy for a from-scratch recipe, right?
  3. Spread in a greased 9×13 pan. Bake the brownies at 350 degrees for about 30 minutes.

Peanut Butter Frosting

While the brownies are baking, make the peanut butter frosting. Now let me tell you, this frosting is my absolute favorite.  If you love peanut butter, you’ll love this frosting, It’s super easy and it tastes like HEAVEN. We found this frosting on accident from allrecipes.com.  We needed a “fix” for a chocolate cake that didn’t come out so well. This turned that almost disastrous chocolate cake into a dream. (If you love this frosting, you’ll love our Nutter Butter Cake!)

To make the frosting, blend 2 sticks of butter, 1 cup of peanut butter, 2 cups of powdered sugar and 3 Tablespoons of milk for about 4 minutes or until it is fluffy.

Frosted Brownies

With small, smooth strokes, put the icing on the cooled brownies.  The amount of icing? It depends, but we did the icing about as thick as the brownie. Because after all, the icing is the best part!
Put on Reese’s Pieces and drizzle on some melted chocolate, if you’d like.  Ooey, Gooey Peanut Butter Goodness.

Serve it to your closest friends and watch them smile.

 (Or, put it in the fridge and eat it yourself!)

Ingredients
 

Brownies:

  • 1 cup unsalted butter
  • 2 1/4 cups granulated sugar
  • 4 large eggs
  • 1 1/4 cups cocoa powder
  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1 tablespoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 2 cups mini chocolate chips

Peanut Butter Frosting:

  • 1 cup creamy peanut butter
  • 3 cups powdered sugar
  • 1 cup softened butter
  • 3 tablespoons milk if needed to get to the correct consistency
  • 1/2 cup Reese's Pieces candy

Instructions
 

Directions for Brownies:

  • Preheat the oven to 350 and lightly grease a 9x13 pan.
  • In a saucepan over low heat, melt the butter, then add the sugar and stir to combine. Heat just until the mixture is hot, but don't let it bubble. Watch for it to start looking shiny as you stir it.
  • In a stand mixer, beat the 4 eggs with the cocoa, salt, baking powder, and vanilla till smooth. 
  • Add the hot butter & sugar mixture to the egg & cocoa mixture, stirring until smooth.
  • Add the flour and chocolate chips, again stirring until smooth. Remember that if you don't want your chocolate chips to melt, let the mixture cool off for about 20 minutes before adding in the chocolate chips.
  • Pour the batter into your prepared pan. Bake for about 30 minutes or until the edges of the brownies look set and the center is slightly puffy.

Directions for Frosting:

  • In a stand mixer, beat together the peanut butter and butter for 2 minutes with the whip attachment. Add in the powdered sugar and beat for an additional 2 minutes, adding milk in if the frosting is not at spreading consistency. 
  • After the brownies have cooled, spread on the icing, as generously as you like. Sprinkle on the Reese's candy. Melt 1 block of semi-sweet chocolate in the microwave for 30 seconds or until melted. Drizzle the chocolate over the top.

  1. These were delicious! The brownie is very dense and almost fudge-like. I prefer that to a more cake-like brownie so I am very pleased. The frosting is to die for. Absolutely delicious. One question, though. Can these sit out or do they need to be refrigerated? I ask because there is a very small amount of milk in the frosting.

    1. Brian, I’m so glad you loved the brownies! I would store them in the fridge since they do have butter and milk in them. Thanks!!

  2. 5 stars
    I loved these brownies, good by themselves but especially good with the frosting! The only thing I might tweak for next time is less powdered sugar in my frosting for a fluffier texture and a more dominate peanut butter taste!

    1. 5 stars
      I followed your suggestion and loved the result! I didn’t need to add any milk, so I was able to store them at room temperature (my preference when using Reese’s pieces/m&m’s).
