Prep Time, Cook Time, and Servings

Prep Time: 25 minutes | Cooking Time: 25 minutes | Total Time: 50 minutes | Servings: 24 slices

Ingredients

For the Brownie Layer:

• 1½ cups unsalted butter, melted
• 1 cup unsweetened cocoa powder
• 3 cups granulated sugar
• 6 large eggs
• 2 teaspoons vanilla extract
• 2 cups all-purpose flour
• 1 teaspoon salt

For the Peanut Butter Fudge Layer:

• 1 cup creamy peanut butter
• ½ cup unsalted butter
• 2 cups powdered sugar
• 2 tablespoons milk

For the Chocolate Glaze:

• 1 cup chocolate chips
• ¼ cup heavy cream
• 2 tablespoons peanut butter

Step-by-Step Instructions

1. Preheat the oven: Set your oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper for easy removal.
2. Make the brownie batter: In a large bowl, whisk the melted butter and cocoa powder until smooth. Add the sugar, eggs, and vanilla extract, whisking until the mixture is glossy and thick. Gently stir in the flour and salt just until combined—do not overmix.
3. Bake the brownie slab: Spread the batter evenly into the prepared pan. Bake for 20–25 minutes, or until the brownies are set but still fudgy in the center. Let them cool completely in the pan.
4. Prepare the peanut butter fudge layer: In a saucepan, melt the peanut butter and butter together over low heat, stirring until smooth. Remove from heat and stir in the powdered sugar and milk until the mixture is thick and spreadable. Spread this evenly over the cooled brownie slab.
5. Make the chocolate glaze: Heat the heavy cream until hot but not boiling. Pour it over the chocolate chips and peanut butter in a bowl, stirring until smooth. Spread the glaze over the peanut butter layer and let it set before slicing.

Pro Tips for Perfect Results

• Use room-temperature eggs for a smoother batter.
• Do not overbake the brownies—they should be slightly fudgy in the center for the best texture.
• For an extra peanut butter kick, swirl a little extra peanut butter into the chocolate glaze.
• Let the brownie slab cool completely before adding the peanut butter fudge layer to prevent melting.
• Use a sharp knife dipped in hot water to slice cleanly through the layers.

Variations and Substitutions

• Gluten-free: Substitute the all-purpose flour with a gluten-free flour blend.
• Healthier swaps: Use natural peanut butter and reduce the sugar slightly for a lighter version.
• Nut-free: Replace peanut butter with sunflower seed butter.
• Dairy-free: Use dairy-free butter and coconut milk instead of heavy cream.

Storage and Reheating Tips

Store the Peanut Butter Fudge Brownie Slab in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, freeze individual slices wrapped in plastic wrap and foil for up to 3 months. Thaw at room temperature before serving.

Frequently Asked Questions

Can I use crunchy peanut butter instead of creamy?

Yes, crunchy peanut butter will add a nice texture, but the fudge layer won’t be as smooth.

Can I make this recipe in a smaller pan?

Yes, but you’ll need to adjust the baking time—thicker brownies will take longer to bake.

Why did my glaze turn grainy?

This can happen if the chocolate isn’t fully melted. Make sure the cream is hot enough to melt the chocolate chips completely.

Can I omit the peanut butter fudge layer?

Absolutely! You can enjoy the brownies plain or with just the chocolate glaze.
