What’s not to love about chocolate and peanut butter? Just think of how popular Peanut Butter Cups are! The salty peanuts and creamy, sweet chocolate are just made to come together. The peanut butter truffle layer in the brownies is made light and fluffy and is the perfect contrast to the fudgy chocolate layers it’s sandwiched between.

Chocolate Peanut Butter Brownies are a rich, fudgy, sweet recipe that looks a lot harder than it is to make. Every ingredient is right from your pantry and it’s actually just three easy recipes stacked on each other. The chocolate brownie base is a classic recipe for brownies and it is topped with a sweetened whipped peanut butter and finished with a melted butter and chocolate topping.

Baking Tips

  • Prep: Preheat your oven to 350 degrees and coat an 8×8 inch pan with cooking spray. If you prefer, you could also use parchment paper.
  • Brownie Layer: Melt the ½ cup butter in a microwave-safe bowl. Whisk the melted butter, sugar, eggs, and vanilla together until smooth. Add in the cocoa powder, flour, salt, and baking powder. Don’t overmix the dry ingredients. Spread the batter evenly into the prepared pan with a spatula. Bake for 25-30 minutes. Use a toothpick to test if the brownie layer is done at 25 minutes. If the toothpick comes out with batter on it bake longer.
  • Creamy Peanut Butter Layer: While the brownies cool, make the peanut butter truffle layer. Use an electric mixer to combine the butter and peanut butter until creamy. Add the powdered sugar and water with the mixer on a low speed. Continue mixing until creamy. Spread the peanut butter mixture over the brownies, after they’ve had 20 minutes to cool. If you put the peanut butter on the brownies while they’re hot, the brownies will just melt the truffle filling.
  • Chocolate Topping Layer: Microwave the chocolate chips and butter in 30-second increments. Stir between each session until melted and smooth. Continue stirring for 1 minute after melting until the chocolate mixture is glossy. Spread the chocolate over the peanut butter, then refrigerate for 30 minutes before serving and slicing.

  • Chocolate Ganache: You can exchange the melted chocolate topping for an equally sweet and rich Chocolate Ganache.
  • Brownie Mix: If you want to simplify the recipe a little, try using a box mix brownie recipe to make the brownie base. One easy way to make box mix brownies richer is by using melted butter in place of the oil it calls for.
  • Peanuts: Try adding some crunch to the recipe by whisking crushed peanuts into the peanut butter truffle layer.
  • Chocolate Chips: For some extra chocolatey goodness, add chocolate chips into the brownie base. You could also use peanut butter chips for more peanut butter flavor.

  1. I made this and it is so wonderful! if you like Reese’s peanut butter cups you will like this even better

    1. I haven’t but to go from a 8×8 pan to a 9×13 pan, you double the recipe. And because there’s not a major difference in the depth, there’s no need to adjust the oven temperature or cooking time (but always test your brownies a few minutes before time is up to ensure you don’t over bake.

  2. These brownies turned out so good! We had just barely made them and it looks like we need another batch asap! We were supposed to take them to a Christmas party, but we ate them all making sure they were “good enough” LOL!

  3. Who wouldn’t want a triple-layer treat? These peanut butter truffle brownies are so good and flavorful! Highly recommended!

  4. Peanut butter truffle brownies are my new family’s favorite! It is so chewy and delicious! Thanks Sabrina for this must try recipe, we love it!

  5. I made these to take to dinner with a friend. She’s dairy free so I used coconut oil in place of butter and dairy free chocolate chips. The top ganache didn’t set up, although if I had refrigerated it longer, I assume it would have. But people loved it with the soft ganache top! Even people who didn’t know they were DF.
