These Peanut Butter Brownies are a huge hit, no matter who tries them. A thick layer of the richest, thickest, and fudgiest brownie topped with a layer of peanut butter filling and homemade whipped cream. On top of that, I added chopped Reese’s Peanut Butter Cups. If you love chocolate and peanut butter, this recipe is a must-try! If you can’t wait to try this recipe, be sure to try my Piggy Pie Dessert too!

Homemade Fudgy Brownies?

Yes, absolutely yes. But, if you happen to want to speed the process up a bit, you can use store bought. Just buy the largest size they have available, which is usually a 9×13 size.

How to Make this Brownie Peanut Butter Dessert

Begin by preparing your brownies. Bake them in a 9×13 pan and then allow them to cool to room temperature.

Prepare the peanut butter filling. You want the filling to be as smooth as possible, so feel free to use your stand mixer.

Make the whipped cream. Set it in the refrigerator until you are ready to assemble the brownie dessert.

Chop 30 mini Reese’s Peanut Butter Cups into quarters. Set aside until you are ready to assemble the brownie dessert. (And then snack on a few too!)

When you are ready to assemble, pour the peanut butter filling over top of the cooled brownies. Spread into an even layer. Carefully place the whipped topping on top of the peanut butter layer. (I used a small offset spatula to even out the layers.) It will be a thin layer. Finally, sprinkle the peanut butter cup pieces over top of the dessert. Place in the refrigerator for 2 hours to set and up to overnight. You can easily cover the dessert with plastic wrap or foil if you want.

How to Store Brownies

Because of the extra layers of toppings, these brownies do need to be refrigetated. They will last, covered, 2-3 days in the refrigerator.

Ingredients

Brownie Layer

  • 4 large eggs, room temperature
  • 2 cups (400 g) granulated sugar
  • ¾ cup (170 g) butter, melted and cooled slightly
  • 1 tablespoon vanilla extract
  • 1 ½ cups (192 g) all-purpose flour
  • cup (43 g) cocoa
  • ½ teaspoon baking powder
  • ¼ teaspoon salt

Peanut Butter Layer

  • 8 ounces cream cheese, softened
  • 1 cup (250 g) creamy peanut butter
  • 1 cup (128 g) confectioners sugar

Whipped Topping Layer

  • 1 cup (238 g) heavy whipping cream
  • ¼ cup (31 g) confectioners sugar

Toppings

  • 30 mini Reese’s Peanut Butter Cups, removed from wrapper and chopped into quarters

Instructions

  • Preheat oven to 350°F.

Brownie Layer

  • In a large bowl add eggs, sugar, melted butter, and vanilla. Whisk until all ingredients are fully incorporated.
  • Add in the flour, cocoa, baking powder, and salt. Stir until just combined.
  • Pour brownie batter into a prepared 9×13 baking dish and bake at 350°F for 30-35 minutes, or until an inserted toothpick is removed mostly clean. (a few crumbs is good!)
  • Set aside to cool to room temperature.

Peanut Butter Layer

  • In a medium bowl, add the cream cheese, peanut butter and use a hand-held mixer to fully incorporate. With the hand mixer on low, pour in the confectioner’s sugar. Mix for about 30 seconds, turn onto high and mix until smooth and creamy, about 1 minute.
  • Set aside.

Whipped Topping Layer

  • In a large bowl or in the bowl of a stand mixer, pour the heavy whipping cream. Whip (or use the whisk attachment on a hand-held mixer) for about 2 minutes, or until soft peaks occur.
  • Add in confectioners sugar and whip until there are firm peaks. (Lift the whisk attachment out and make sure the whipped topping holds its shape.)

Assembly

  • Pour the peanut butter filling over top of the cooled brownies. Spread into an even layer. Carefully place the whipped topping on top of the peanut butter layer. (I used a small offset spatula to even out the layers.) It will be a thin layer.

  1. Have you made any of the chocolate cocoa bombs please tell how and size of the molds and where you find the molds at thanks in advance

  2. When my sister decided not to come to Thanksgiving (she is the baker in the family!) I whipped this up for dessert. Everyone loved it so much they have asked for it every year for Thanksgiving. Thank you for an awesome and sweet recipe!

  3. I can’t decide which bar I want to make to take to a potluck at church Sunday. I might just make both. They both sound so yummy. I love chocolate and peanut butter together.

  4. Try boxed brownie mix. Make 12 muffins in paper. Bake accordingly. Unwrap snack sized pb cups and refrigerate before brownies bake. After taking brownies out of the oven let cool for 5-10 minutes. Push each muffin brownie with a pb cup down into the brownie and let cool completely. So indulgent.

  5. Had this delicious brownie treat at a get together ❤last evening. WOW only way to describe it. We have Football parties and this is going to be made.👍🏈🎉
