Sometimes a name just says it all, like these peanut butter brownies—call it out and watch the kids come running! The classic combo of chocolate and peanut butter is at its absolute best in this brownie recipe: smooth peanut butter is sandwiched between two layers of dense, chewy dark chocolate brownie. 

Ever wonder how professional bakeries get that center layer so flat and even? It's all thanks to the freezer: Once frozen, the peanut butter layer can be picked up and placed right on the brownie batter without a sticky mess. As the brownies bake, the peanut butter will soften and become perfectly gooey. Wow any crowd with these brownies at the next cookie swap or bake sale; otherwise, make a batch for any lovers of chocolate dessert in your home!

What does the percentage mean on a chocolate bar?

Chocolate bars are made of unsweetened cocoa, cocoa butter, milk, and sugar. The percentage is the amount of cocoa compared to the other ingredients. This recipe calls for a pretty dark chocolate, 72%, to balance out the sweetness and stand up to the peanut butter flavor. 

Can brownies be overmixed?

It's pretty hard to overmix a brownie batter since there's not a lot of flour (the source of the gluten that can make baked goods tough). Still, keep the speed of your stand mixer low to incorporate less air and keep the brownies extra fudgy. 

Can peanut butter brownies be made ahead?

The peanut butter layer can be frozen a few days ahead. Make the brownies up to one day ahead.

Ingredients

  • 1 1/2 cups

    creamy peanut butter

  • 1/2 cup

    all-purpose flour

  • 2/3 cup

    unsweetened cocoa powder

  • 3/4 cup

    salted butter

  • 3 oz.

    dark chocolate bar (72%), chopped

  • 1 1/4 cups

    granulated sugar

  • 1/4 tsp.

    kosher salt

  • 1 1/2 tsp.

    vanilla

  • 3

    large eggs

  • 1/3 cup

    semisweet chocolate chips

  • 1/3 cup

    peanut butter chips

Directions

    1. Step 1Preheat the oven to 350°. Lightly grease a 9-by-9-inch square baking pan then line with parchment paper, leaving an overhang on all sides. Microwave the peanut butter for 30 seconds; stir. Repeat as necessary until peanut butter is pourable. Pour into the prepared pan. Freeze until firm, about 1 hour. Remove the peanut butter layer and transfer to a small sheet tray. Store in the freezer until ready to use. 
    2. Step 2Sift together the flour and cocoa powder in a medium mixing bowl.
    3. Step 3Melt the butter and chocolate in a medium saucepan over medium heat, stirring often. Remove from heat.
    4. Step 4Beat the sugar, salt, vanilla, and eggs in a large bowl with an electric mixer at medium-high speed until fluffy, about 3 minutes. Slowly drizzle in the melted chocolate mixture on low speed until combined. Beat in the flour mixture on low speed until just combined. 
    5. Step 5Pour half of the batter into the prepared pan. Remove peanut butter layer from the freezer, and place on top of brownie batter. Top with the remaining half of the brownie batter, and spread to even out the top. Sprinkle the top with the chocolate chips and peanut butter chips.
    6. Step 6Bake in the preheated oven for about 40 minutes or until puffed, dry to the touch, and set on the top (a wooden pick inserted in the center will not come out clean). Cool completely in the pan on a wire rack, about 3 hours. Cut into 16 squares.

Tip: The brownies can be made a day ahead and left uncut until ready to serve.
