The image shows a close-up of a layered dessert bar on a white marbled surface. The dessert has four distinct layers: the bottom layer is a dark brown, smooth and firm crust, the second layer is a creamy light brown, slightly thicker and soft-looking, the third layer is a thin white layer that is smooth and glossy, and the top layer is a marbled mix of light and dark brown swirls with a glossy texture. Scattered on the top marbled layer are bright red, yellow, and orange candy pieces, adding spots of color. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/2 cup (1 stick) unsalted butter, melted
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/3 cup cocoa powder
1/2 cup all-purpose flour
1/4 teaspoon salt
1/4 teaspoon baking powder
1 cup chocolate chips
1/2 cup creamy peanut butter
1/4 cup powdered sugar
1/2 cup Reese’s Pieces candies

Instructions

Step 1: Preheat your oven to 350°F (175°C). Grease an 8-inch square baking pan or line it with parchment paper for easy removal.
Step 2: In a large bowl, combine the melted butter, granulated sugar, eggs, and vanilla extract. Beat the mixture until smooth and well blended.
Step 3: Add the cocoa powder, all-purpose flour, salt, and baking powder to the wet ingredients. Mix until everything is well combined, being careful not to overmix.
Step 4: Fold in the chocolate chips gently to distribute them evenly throughout the batter.
Step 5: Pour the brownie batter into the prepared pan and spread it evenly with a spatula.
Step 6: In a separate bowl, mix the creamy peanut butter with the powdered sugar until smooth and creamy.
Step 7: Drop spoonfuls of the peanut butter mixture over the brownie batter. Use a knife or skewer to swirl the peanut butter through the batter for a marbled effect.
Step 8: Sprinkle the Reese’s Pieces candies evenly on top of the marbled batter.
Step 9: Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Step 10: Allow the brownies to cool completely in the pan before cutting into squares and serving.

Tips & Variations

For extra gooey brownies, slightly underbake by removing them at 25 minutes. They will continue to cook as they cool.
Swap Reese’s Pieces for chopped peanut butter cups or chopped nuts for added texture and flavor.
Use crunchy peanut butter for a bit of extra crunch in the swirl.

Storage

Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Reheat briefly in the microwave to enjoy warm, or eat cold for a fudgy texture.

How to Serve

The image shows a close-up of two square layered dessert bars placed side by side on a white marbled surface. Each bar has three visible layers: the bottom layer is dark brown and crumbly, the middle layer is creamy white and smooth with some bubbling texture, and the top layer is a glossy swirl of dark and light brown chocolate, creating a marbled pattern. On top of the swirl, small round candies in bright red, yellow, and orange are scattered randomly, adding pops of color. The overall look is rich and gooey, with the top layer slightly dripping over the edges. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use natural peanut butter in this recipe?

Yes, you can use natural peanut butter, but it may be slightly less smooth. Stir well before mixing with powdered sugar to ensure an even swirl.

Can I make these gluten-free?

Absolutely! Substitute the all-purpose flour with a gluten-free baking blend that measures cup-for-cup. The texture might vary slightly but will still be delicious.
