- 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
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 bake evenly.
Step 2: Prepare Your Baking Pan
Line the 9×9 inch baking pan with parchment paper. Leave some overhang on the sides to make removing the brownies easier later.
Step 3: Melt Chocolate and Butter
In a mixing bowl, combine the chopped semisweet baking chocolate and unsalted butter. Microwave them together in 30-second intervals until fully melted. Stir until smooth.
Step 4: Mix Wet Ingredients
In another bowl, whisk together granulated sugar, eggs, egg yolk, vanilla extract, and creamy peanut butter. Mix until well combined.
Step 5: Combine Mixtures
Pour the melted chocolate mixture into the peanut butter mixture. Stir until thoroughly mixed.
Step 6: Add Dry Ingredients
Sift together all-purpose flour, cocoa powder, and fine sea salt in a separate bowl. Gradually fold this dry mix into your wet ingredients until just combined.
Step 7: Bake the Brownies
Pour half of your brownie batter into the prepared pan. Spread it evenly across the bottom. Then add spoonfuls of peanut butter on top before pouring the remaining brownie batter over it. Use a knife to swirl gently for marbled effect.
Bake in preheated oven for about 30 minutes or until a toothpick comes out with a few moist crumbs attached.
Step 8: Cool and Serve
Allow the brownies to cool in the pan for at least 20 minutes before lifting them out using parchment overhang. Cut into squares and enjoy your delicious Peanut Butter Stuffed Brownies!

How to Perfect Peanut Butter Stuffed Brownies
To achieve the best results when making Peanut Butter Stuffed Brownies, consider these helpful tips.
- Use Room Temperature Ingredients: Make sure your eggs and butter are at room temperature for better mixing.
- Don’t Overmix the Batter: Mix just until combined to keep the brownies fudgy instead of cakey.
- Check for Doneness Early: Start checking your brownies a few minutes before the suggested cook time; they should be set but still slightly soft in the center.
- Let Them Cool Completely: Allowing them to cool helps them set properly, making them easier to cut into squares.

Common Mistakes to Avoid
When making Peanut Butter Stuffed Brownies, it’s easy to make a few common mistakes. Here are some tips to help you get it right.
- Using natural peanut butter: Natural peanut butter separates and doesn’t provide the creamy texture needed for stuffing. Stick to conventional peanut butter for best results.
- Not measuring ingredients accurately: Baking is a science. Use a kitchen scale or measuring cups for precise amounts, especially for flour and cocoa powder.
- Overbaking the brownies: Overbaking can lead to dry brownies. Keep an eye on them and do the toothpick test; it should come out with a few moist crumbs.
- Skipping the cooling time: Letting the brownies cool completely helps them set properly and makes cutting easier. Patience pays off!
- Ignoring oven temperature: Make sure your oven is preheated to the correct temperature before baking. An oven thermometer can help ensure accuracy.
