For the Brownies:
- 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
Start by preheating your oven to 350°F (175°C). This ensures that your brownies bake evenly.
Step 2: Prepare Your Baking Pan
Line an 8×8 inch baking pan with parchment paper, allowing some overhang for easy removal later.
Step 3: Melt Chocolate and Butter
In a microwave-safe bowl, combine the chopped semisweet baking chocolate and unsalted butter. Heat in short intervals until melted, stirring between each interval until smooth.
Step 4: Mix Wet Ingredients
In another bowl, whisk together the granulated sugar, eggs, egg yolk, and vanilla extract until combined. Pour in the melted chocolate mixture and stir until well blended.
Step 5: Combine Dry Ingredients
In a separate bowl, mix together the all-purpose flour, sifted cocoa powder, and fine sea salt. Gradually fold this mixture into the wet ingredients using a rubber spatula until just combined.
Step 6: Assemble the Brownies
Pour half of the brownie batter into the prepared pan. Spread it evenly across the bottom. Then dollop spoonfuls of creamy peanut butter over this layer. Finally, cover with the remaining brownie batter and spread it out gently.
Step 7: Bake
Place in the preheated oven and bake for about 30 minutes or until a toothpick inserted in the center comes out with moist crumbs.
Step 8: Cool and Serve
Once baked, allow the brownies to cool in the pan on a wire rack before lifting them out using the parchment paper overhang. Cut into squares and enjoy your delicious Peanut Butter Stuffed Brownies!
These brownies are sure to become a favorite!

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: Bringing butter and eggs to room temperature helps create a smoother batter, leading to better texture.
Choose creamy peanut butter: For consistent filling and flavor, stick with conventional creamy peanut butter instead of natural varieties.
Don’t overmix: Mix just until combined; overmixing can lead to tough brownies.
Check for doneness: Insert a toothpick into the center; it should come out slightly moist but not wet, ensuring perfectly fudgy brownies.
Cool completely before cutting: Allowing your brownies to cool fully helps them set and makes cutting easier without crumbling.
Best Side Dishes for Peanut Butter Stuffed Brownies
Pairing side dishes with your Peanut Butter Stuffed Brownies can enhance your dessert experience. Here are some great options:
Fresh Fruit Salad: A mix of seasonal fruits adds freshness and balances the richness of the brownies.
Chocolate Covered Strawberries: These sweet treats complement the chocolate flavor while adding a fun, festive touch.
Ice Cream Sundae Bar: Set up a sundae station where guests can add toppings like nuts, sprinkles, and sauces to their ice cream alongside brownies.
Chia Seed Pudding: This creamy, plant-based pudding provides a light contrast and is packed with nutrients.
Nutty Granola Parfait: Layer granola, yogurt, and fruit for a crunchy yet creamy side dish that pairs well with brownies.
Coconut Whipped Cream: This dairy-free alternative adds sweetness and tropical flavor without overpowering the brownies.
Common Mistakes to Avoid
It’s easy to make small errors when baking Peanut Butter Stuffed Brownies. Here are some common mistakes and tips on how to avoid them.
- Using natural peanut butter: Natural peanut butter can affect the texture of your brownies. Stick to creamy conventional peanut butter for the best results.
- Not measuring ingredients accurately: Baking is a science, so inaccurate measurements can ruin your brownies. Use a kitchen scale or measuring cups for precise amounts.
- Overmixing the batter: Overmixing can lead to tough brownies. Mix just until the ingredients are combined for a fudgy texture.
- Skipping the cooling time: Allowing brownies to cool in the pan enhances their flavor and texture. Be patient; cooling improves your final product.
