Ingredients
1 cup unsalted butter
1 cup granulated sugar
1 cup brown sugar
4 large eggs
2 teaspoons vanilla extract
1 cup all-purpose flour
1 cup unsweetened cocoa powder
1/2 teaspoon salt
3/4 cup marshmallow fluff
3/4 cup creamy peanut butter
Instructions
1. Preheat oven to 350°F and line a 9×13-inch baking pan with parchment paper.
2. In a large bowl, melt the butter and whisk in granulated and brown sugar until smooth.
3. Add eggs and vanilla extract, whisking until thick and glossy.
4. Fold in cocoa powder, flour, and salt until just combined.
5. Pour the batter into the prepared pan and spread evenly.
6. Dollop marshmallow fluff and peanut butter over the top.
7. Use a knife to gently swirl them through the top layer of batter.
8. Bake for 28–32 minutes, until edges are set and the center is slightly soft.
9. Cool completely in the pan before slicing into squares.
10. Store in an airtight container or freeze for later.
Notes
Use classic creamy peanut butter, not natural, for the best swirl and texture.
Don’t overmix the batter once you add the flour and cocoa powder to keep brownies fudgy.
For perfect slices, chill the brownies and cut with a clean, sharp knife.
