Ingredients
To make these Peanut Butter Stuffed Brownies, gather the following ingredients:
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
For the Dry Ingredients
- 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 will bake evenly from the start.
Step 2: Prepare the Baking Pan
Line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides. This makes it easier to lift out the brownies later.
Step 3: Melt Chocolate and Butter
In a microwave-safe bowl, combine the chopped semisweet chocolate and unsalted butter. Heat in short intervals, stirring frequently until melted and smooth.
Step 4: Mix Wet Ingredients
In a large mixing bowl, whisk together granulated sugar, eggs, additional egg yolk, vanilla extract, and melted chocolate mixture until well combined.
Step 5: Incorporate Dry Ingredients
Sift together all-purpose flour, cocoa powder, and sea salt. Gradually add this dry mixture into the wet ingredients using a rubber spatula until just combined; do not overmix.
Step 6: Assemble Brownies
Pour half of the brownie batter into the prepared pan. Spread it evenly. Then dollop spoonfuls of peanut butter on top before adding the remaining brownie batter over it. Spread gently to cover.
Step 7: Bake
Bake in preheated oven for about 30 minutes or until a toothpick inserted comes out mostly clean with some moist crumbs attached.
Step 8: Cool and Serve
Allow to cool in the pan for at least 15 minutes before lifting out using parchment paper. Cut into squares and enjoy!

Common Mistakes to Avoid
When making Peanut Butter Stuffed Brownies, some common mistakes can lead to less-than-perfect results. Here’s how to avoid them:

- Using natural peanut butter: Natural peanut butter can alter the consistency of your filling. Stick to creamy conventional peanut butter for the best results.
- Overmixing the batter: Mixing too much can make brownies tough. Mix just until combined for a soft and chewy brownie.
- Not letting them cool: Cutting into brownies too soon can result in a messy serving. Allow them to cool completely for clean slices.
