Short Description
Fudgy, chocolatey brownies with a gooey peanut butter center—these Stuffed Peanut Butter Brownies are an indulgent treat that’s as easy to make as it is delicious to eat.
Ingredients
For the brownie layer:
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 tsp salt
- 1/2 tsp baking powder
For the peanut butter filling:
- 3/4 cup creamy peanut butter
- 1/4 cup powdered sugar
- 1/4 cup butter, softened
- 1/2 tsp vanilla extract
Tools Needed
- 9×13 inch baking pan
- Mixing bowls
- Whisk or electric mixer
- Rubber spatula
- Parchment paper (optional, for easy removal)
Instructions
Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C). Grease or line a 9×13 baking dish with parchment paper.
Step 2: Make the Brownie Batter
In a large bowl, whisk together the melted butter and sugar. Add eggs one at a time, beating well after each. Stir in vanilla. In another bowl, sift together the flour, cocoa powder, salt, and baking powder. Add the dry ingredients to the wet mixture and stir until combined. Set aside.
Step 3: Make the Peanut Butter Filling
In a separate bowl, mix peanut butter, powdered sugar, softened butter, and vanilla extract until smooth and creamy.
Step 4: Layer the Brownies
Pour half of the brownie batter into the prepared pan and smooth out. Drop spoonfuls of the peanut butter mixture over the batter and gently spread it into an even layer. Top with the remaining brownie batter and spread to cover.
Step 5: Bake
Bake for 30–35 minutes, or until the edges are set and a toothpick inserted in the center comes out with moist crumbs.
Step 6: Cool & Slice
Let the brownies cool completely before slicing. This helps the peanut butter layer set nicely inside.
