After one bite of these Peanut Butter Brownies, you will agree that peanut butter and chocolate are a match made in heaven. Rich, decadent, and delicious – these brownies will satisfy your cravings for something sweet.

If you want to jazz up the recipe, you can add miniature Reese’s Cups, Reese’s Pieces, or peanut butter chips to either batter. Or go all out and add Reese’s Pieces to the peanut butter layer and miniature peanut butter cups to the chocolate layer. Be warned: you just might find it hard to have only one brownie.
🥘Brownie Ingredients
For these delicious brownies, you need the following ingredients:
Chocolate Layers
- ½ cup all-purpose flour
- ½ cup unsweetened cocoa powder
- ⅛ teaspoon salt
- ½ cup unsalted butter, melted and cooled
- 1 cup granulated sugar
- 2 large eggs
- 1½ teaspoons vanilla extract
Peanut Butter Layer
- ⅓ cup creamy peanut butter
- 2 Tablespoon unsalted butter melted
- ⅓ cup granulated sugar
- ¼ cup packed brown sugar
- 1 large egg
- ½ teaspoon real vanilla extract
- ½ cup all-purpose flour
- 1 teaspoon baking powder
- ⅛ teaspoon salt
🔪 Instructions
That’s right – these brownies have two delicious layers. The bottom is made with creamy peanut butter that is combined with both brown and regular sugar, flour, egg, butter, vanilla, and leaveners.
To make them, start by preheating your oven to 350°F and line an 8” x 8” pan with parchment paper and spray with non-stick cooking spray.
For the bottom peanut butter layer, combine peanut butter, melted butter, sugar, brown sugar, egg, and vanilla in a large mixing bowl. In a small bowl, combine flour, baking powder, and salt. Add the dry ingredients to the peanut butter mixture.
Spread the peanut butter brownie layer on the bottom of the pan.
To make the chocolate layer, combine flour, cocoa powder, and salt in a medium bowl. In a separate bowl, whisk together the melted butter, sugar, eggs, and vanilla. Lightly fold the dry ingredients into the wet ingredients. Do not mix or the brownies will turn out cake-like.
Top the peanut butter layer with the brownie batter, spreading the batters for both layers out evenly.
⏲️ Baking Time
Bake for 22 minutes. Brownies will still be soft and gooey, but will finish setting while they cool. Once baked, the two layers make for one delicious brownie.
Once the brownies have baked and cooled, you can cut them into individual portions and freeze them. Wrap each slice in plastic wrap and place them in a freezer zip-top bag to help preserve their freshness.
