Brownie Peanut Butter Dessert

filed under: Brownies on April 11, 2019

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!

You all know how much I love brownies, as I have 20+ brownie recipes on my website! (This brownie recipe is my favorite forever and always and no one can convince me otherwise.) So I consider it my personal mission in life to only share the best brownie recipes possible. They have to be packed with chocolate flavor. They have to have an element of ooey gooey to them. And they have to be homemade. As much as I enjoy any brownie (box mix or not) there is just something so satisfying about a perfectly baked homemade brownie.

This brownie is paired with a delectable peanut butter layer and topped with homemade whipped cream. I could probably eat the peanut butter and whipped cream in a bowl on its own, but if I can layer it on top of a brownie, why not?

This recipe is basic. A few simple ingredients come together and bake into a fantastic brownie that is the perfect foundation for this layered brownie dessert. It’s the size that matters here. I didn’t want a skinny layer of chewy, cakey brownie deliciousness, I wanted a THICK layer to compliment this dessert. And this recipe is perfect for that!

Peanut Butter Filling

Three (3!!) ingredients are all you need for this layer, arguably the best layer.

  • cream cheese
  • peanut butter
  • confectioners sugar

Be sure to use creamy peanut butter for this, as you want a silky smooth filling that will feel like velvet on your tongue. Not to mention taste amazing!

Next whip up your homemade whipped cream. I went back to basics here and simply used heavy whipping cream with a little confectioners sugar. I made my whipped cream layer fairly thin, but you can easily double the recipe below if you want an extra thick portion of whipped topping!

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 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.

  • 4 large eggs, room temperature
  • 2 cups (400g) granulated sugar
  • 3/4 cup (170g) butter, melted and cooled slightly
  • 1 tablespoon vanilla extract
  • 1 1/2 cups (192g) all-purpose flour
  • 1/3 cup (43g) cocoa
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
Peanut Butter Layer
  • 8 ounces cream cheese, softened
  • 1 cup (250g) creamy peanut butter
  • 1 cup (128g) confectioners sugar
Whipped Topping Layer
  • 1 cup (238g) heavy whipping cream
  • 1/4 cup (31g) confectioners sugar
  • 30 mini Reese's Peanut Butter Cups, removed from wrapper and chopped into quarters
  1. Preheat oven to 350°F.

Brownie Layer
  1. In a large bowl add eggs, sugar, melted butter, and vanilla. Whisk until all ingredients are fully incorporated.
  2. Add in the flour, cocoa, baking powder, and salt. Stir until just combined.
  3. Pour brownie batter into a prepared 9x13 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!)

  4. Set aside to cool to room temperature.
Peanut Butter Layer
  1. 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.
  2. Set aside.
Whipped Topping Layer
  1. 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.
  2. 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.)
  1. 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.

      Awwwwww… thank you! That is so kind of you to say!

  • lori says:

    have you ever tried omitting the flour on the amazing brownie dessert to make it gluten free?

    • Amanda Rettke says:

      I have not, I am not a gluten free baker.

  • Patricia says:

    I made something quite similar and entered it in our local County Fair. I won the culinary division with that! My version is slightly different but similar.

  • Donna says:

    I receive your recipes in my inbox, but the graphics you use are SO large I can never see what it is. Can you do anything about that in the future?

    • Amanda Rettke says:

      I am so sorry. Will try and fix it!

  • kendall coffing says:

    You say, “prepared” pan but it doesn’t say how, greased, floured, both?

    • Amanda Rettke says:

      IT really depends on personal preference. Some want to butter + flour, some use bakers spray, some prefer goup. All work.

  • Yolanda C Kennedy says:

    Looks so good! I’m going to bake them this weekend.

  • Gail armitage says:

    Could you use cool whip for topping?

    Is it cocoa powder or prepares hot cocoa mix?

  • Scarlet says:

    Wowzer. These peanut butter brownie bars look amazing. I think I will bring these to a dinner party this weekend. Pinning now to try very soon!

  • Kim says:

    I made these for a food day at work yesterday. I brought back only 3 tiny pieces. They were a big hit.

  • Kim D. says:

    In the second step you say to set aside the peanut butter layer, but it never says what to do with it. I’m assuming it isn’t baked and is just spread on top of the brownie layer? Just clarifying. I’m making this for a party on Friday night. It sounds wonderful.

    • Elizabeth Keeney says:

      Hi, Kim! I work with iambaker and am happy to help with questions. Yes, you would pour and spread the peanut butter layer over the top of the cooled brownies. It is part of the assembly instructions. Have a great day!

  • Kim Diefenbach says:
