For the Brownie Base
- 1 1/4 cups (336 grams) creamy conventional peanut butter (NOT ‘natural’)
- 10 tablespoons (142 grams) unsalted butter
- 4 ounces (113 grams) semisweet baking chocolate, chopped
- 1 cup (200 grams) granulated sugar
- 2 large eggs plus 1 egg yolk
- 1 teaspoon vanilla extract
- 1/2 cup (64 grams) all-purpose flour
- 1/4 cup (25 grams) unsweetened cocoa powder, sifted
- 1/4 teaspoon fine sea salt
How to Make Peanut Butter Stuffed Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your brownies bake evenly.
Step 2: Prepare the Baking Pan
Line an 8×8 inch baking pan with parchment paper. Leave some overhang on the sides to make removing the brownies easier once baked.
Step 3: Melt Chocolate and Butter
In a mixing bowl, combine the chopped semisweet baking chocolate and unsalted butter. Melt them together in the microwave in 30-second intervals until smooth. Stir well after each interval.
Step 4: Mix Wet Ingredients
In a separate bowl, whisk together granulated sugar, eggs, egg yolk, and vanilla extract until well combined. Add the melted chocolate mixture to this bowl and stir until fully incorporated.
Step 5: Combine Dry Ingredients
In another bowl, sift together all-purpose flour, cocoa powder, and fine sea salt. Gradually add this dry mixture into the wet ingredients using a rubber spatula until just combined.
Step 6: Layer with Peanut Butter
Pour half of the brownie batter into the prepared pan. Spread it evenly before dolloping spoonfuls of creamy peanut butter over it. Pour the remaining brownie batter on top, spreading it gently to cover.
Step 7: Bake
Bake in your preheated oven for about 30 minutes or until a toothpick inserted comes out mostly clean. Let cool before slicing into squares.

How to Perfect Peanut Butter Stuffed Brownies
Creating the perfect Peanut Butter Stuffed Brownies requires attention to detail. Here are some tips to ensure your brownies turn out delicious every time.
-
Use Room Temperature Ingredients: Make sure your eggs and butter are at room temperature. This helps create a smoother batter and ensures better mixing.
-
Don’t Overmix the Batter: Stir just until combined to avoid tough brownies. Overmixing can lead to dense results instead of fudgy goodness.
-
Check for Doneness: Bake until the edges are set but the center is still slightly soft. This ensures a fudgy texture without being undercooked.
-
Let Them Cool Before Cutting: Allow the brownies to cool completely in the pan before slicing. This helps maintain their shape and makes cutting easier.
-
Experiment with Toppings: Try adding chopped nuts, sea salt, or additional chocolate chips on top before baking for added texture and flavor.
-
Store Properly: Keep leftovers in an airtight container at room temperature or in the fridge for up to one week for best freshness.

Common Mistakes to Avoid
Avoiding common mistakes can elevate your Peanut Butter Stuffed Brownies to perfection. Here are a few key pitfalls to sidestep:
- Using Natural Peanut Butter: Natural peanut butter can separate and affect the texture. Stick with creamy conventional peanut butter for consistent results.
- Overbaking the Brownies: Overbaking can lead to dry brownies. Keep an eye on them during the last few minutes of baking.
- Not Measuring Ingredients Accurately: Incorrect measurements can alter the brownie’s texture. Use a kitchen scale for precise ingredient amounts.
- Skipping the Cooling Time: Cutting into warm brownies makes them crumble. Allow them to cool completely in the pan before slicing.
- Ignoring the Quality of Chocolate: Using low-quality chocolate can result in less flavor. Choose high-quality semisweet chocolate for a richer taste.
