Ingredients You’ll Need
For the Peanut Butter Layer
- 1 cup (250g) smooth peanut butter (regular spread like Skippy’s or Bega, not natural)
- 1 teaspoon salt flakes, divided
For the Brownie Batter
- 200g (14 tbsp) unsalted butter
- 1 1/4 cups (200g) dark chocolate chips (semi-sweet)
- 1 cup brown sugar, loosely packed
- 3 large eggs, lightly beaten
- 1 teaspoon vanilla extract
- 1/2 cup plain flour
- 1/4 cup cocoa powder
- 1/8 teaspoon cooking salt or kosher salt
How to Make Easy Peanut Butter Stuffed Brownies
Step 1: Prepare the Peanut Butter Slab
Line an 8-inch (20cm) square pan with parchment paper. Warm the peanut butter in the microwave for about 30 seconds so it’s spreadable. Pour it into the pan, spread evenly, and sprinkle with half of the sea salt flakes. Freeze for 2–3 hours until solid. Lift it out using the paper and keep frozen while making the brownie batter.
Step 2: Make the Brownie Batter
Preheat your oven to 180°C (350°F). In a microwave-safe bowl, melt butter and chocolate together in 30-second bursts, stirring until smooth. Mix in brown sugar, then whisk in eggs and vanilla until glossy. Add flour, cocoa powder, and salt. Stir gently until combined.
Step 3: Assemble the Brownies
Line your baking pan again with parchment paper. Pour half the brownie batter into the pan. Place the frozen peanut butter slab on top, then cover with the remaining batter.
Step 4: Swirl and Bake
Warm the reserved 2 tablespoons of peanut butter and drizzle it over the top. Use a knife or spoon to create swirls. Bake for 32 minutes until the edges are firm but the center is slightly jiggly (it sets as it cools).
Step 5: Cool and Slice
Cool in the pan for 1 hour at room temperature, then refrigerate for at least 3 hours before slicing. This ensures the peanut butter layer stays neat and creamy. Cut into 16 squares and enjoy!
