Ingredients

- 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

- 1/4 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 your brownies bake evenly.
Step 2: Prepare the Baking Pan
Line your 9×9 inch baking pan with parchment paper. This helps prevent sticking and makes cleanup easier.
Step 3: Melt the Chocolate and Butter
In a saucepan over low heat, combine the chopped semisweet chocolate and unsalted butter. Stir until melted and smooth.
Step 4: Mix Wet Ingredients
In a mixing bowl, whisk together the granulated sugar, eggs, egg yolk, vanilla extract, and peanut butter until well combined.
Step 5: Combine Mixtures
Pour the melted chocolate mixture into the wet ingredients. Stir until fully incorporated.
Step 6: Add Dry Ingredients
Sift together the flour, cocoa powder, and sea salt in another bowl. Gradually fold this dry mixture into the wet mixture using a rubber spatula until just combined.
Step 7: Bake the Brownies
Pour half of the brownie batter into your prepared pan. Spread it evenly. Add dollops of remaining peanut butter on top before pouring the second half of brownie batter over it. Bake for about 30 minutes or until a toothpick comes out with moist crumbs.
Step 8: Cool and Slice
Allow brownies to cool in the pan before lifting them out using parchment paper. Cut into squares and enjoy!

How to Perfect Peanut Butter Stuffed Brownies
To achieve the best Peanut Butter Stuffed Brownies, consider these helpful tips that will ensure your baking success.
-
Use Room Temperature Ingredients: Allow eggs and butter to reach room temperature before mixing. This helps create a smoother batter and evenly baked brownies.
-
Sift Cocoa Powder: Sifting cocoa powder before adding it to your mixture prevents lumps and ensures a consistent flavor throughout.
-
Don’t Overmix: Mix ingredients just until combined. Overmixing can lead to dense brownies instead of fudgy ones.
-
Use Quality Chocolate: Opt for high-quality semisweet chocolate for melting. It greatly enhances the flavor of your brownies.
-
Let Them Cool: Allow your brownies to cool completely in the pan before cutting. This helps them set up nicely for cleaner slices.

Common Mistakes to Avoid
Making Peanut Butter Stuffed Brownies can be a delightful experience, but certain mistakes can hinder your results.
- Using natural peanut butter: Natural peanut butter can separate and become oily. Stick with conventional creamy peanut butter for consistent texture.
- Skipping the sifting step: Not sifting your cocoa powder can lead to clumps in the batter. Always sift it to ensure smoothness.
- Overbaking the brownies: Baking too long can dry out your brownies. Check for doneness a few minutes early by inserting a toothpick; it should come out with moist crumbs.
- Not letting them cool: Cutting into warm brownies can result in a messy presentation. Allow them to cool completely before slicing for neat squares.
- Ignoring ingredient temperature: Cold ingredients can affect the batter’s consistency. Use room temperature eggs and butter for better mixing.
