Ingredients
To create these delicious 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
- 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). Grease your baking dish lightly with butter or line it with parchment paper for easy removal.
Step 2: Melt Chocolate and Butter
In a medium saucepan over low heat, combine the chopped semisweet chocolate and unsalted butter. Stir continuously until melted and smooth. Remove from heat and let cool slightly.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine granulated sugar, eggs, egg yolk, and vanilla extract. Use an electric mixer or whisk to blend until well combined. Slowly add in the cooled chocolate mixture while continuing to mix.
Step 4: Combine Dry Ingredients
In another bowl, sift together all-purpose flour, cocoa powder, and sea salt. Gradually fold this dry mixture into the wet ingredients using a rubber spatula until just combined.
Step 5: Assemble Brownies
Pour half of the brownie batter into your prepared baking dish. Spread it evenly across the bottom. Then dollop spoonfuls of peanut butter over this layer. Pour the remaining brownie batter on top and gently spread it to cover the peanut butter.
Step 6: Bake
Place in preheated oven and bake for about 30 minutes or until a toothpick inserted into the center comes out clean but moist. Allow brownies to cool before slicing into squares.

How to Perfect Peanut Butter Stuffed Brownies
To achieve the best Peanut Butter Stuffed Brownies, follow these simple tips. Each step can make a significant difference in your final result.
Use Quality Ingredients: High-quality chocolate and peanut butter will enhance the flavor and texture of your brownies.
Don’t Overmix: Mix just until combined to keep the brownies fudgy and moist. Overmixing can lead to tough brownies.
Check Doneness Carefully: Use a toothpick to check if they are done; it should come out with moist crumbs, not clean.
Cool Completely Before Cutting: Allow the brownies to cool completely before cutting them. This helps maintain their structure and prevents them from falling apart.
Store Properly: Keep leftovers in an airtight container at room temperature for up to three days or refrigerate for longer freshness.
Best Side Dishes for Peanut Butter Stuffed Brownies
Peanut Butter Stuffed Brownies pair well with various side dishes, making them even more enjoyable. Here are some great options:
Vanilla Ice Cream: The classic choice! Vanilla ice cream’s creamy texture complements the richness of the brownies perfectly.
Fresh Berries: Mixed berries add a tartness that contrasts beautifully with sweet brownies, making them refreshing.
Chocolate Mousse: A light chocolate mousse provides an elegant touch while reinforcing the chocolate flavor profile.
Fruit Salad: A simple fruit salad can lighten up dessert time, offering freshness alongside your decadent treats.
Coffee or Espresso: Strong coffee enhances the chocolate notes in your brownies, creating an indulgent combination that’s hard to resist.
Milkshake: A thick shake can turn this dessert into a full meal! Blend with ice cream and milk for extra sweetness and thickness.
Nut Butter Dip: Serve almond or cashew butter on the side for an extra nutty flavor that complements everything beautifully.
Coconut Whipped Cream: For those who enjoy tropical flavors, coconut whipped cream adds a unique twist to traditional toppings.
Common Mistakes to Avoid
Making Peanut Butter Stuffed Brownies can be simple, but there are some common pitfalls to watch out for.
- Using Natural Peanut Butter – Natural peanut butter can separate and not provide the creamy texture needed for stuffing. Stick to conventional peanut butter for best results.
- Overmixing the Batter – Overmixing can make your brownies tough instead of fudgy. Mix until just combined and avoid overworking the batter.
- Not Sifting Cocoa Powder – If you skip sifting the cocoa powder, you may end up with clumps in your batter. Always sift it to ensure a smooth mixture.
- Skipping the Egg Yolk – The extra yolk adds richness and moisture. Don’t skip it if you want that perfect fudgy texture.
- Using Cold Ingredients – Cold butter or eggs can lead to uneven baking. Allow them to reach room temperature before mixing.
