Ingredients
Scale
Brownie Base
- 1 cup unsalted butter
- 1 cup granulated sugar
- 1 cup brown sugar
- 3 large eggs
- 2 teaspoons vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt
Swirl Toppings
- 3/4 cup marshmallow fluff
- 3/4 cup creamy peanut butter
- 1/2 cup chocolate chips or chunks (optional)
Instructions
- Preheat and prepare pan: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper for easy removal of the brownies.
- Melt butter: Melt the unsalted butter in a saucepan or microwave-safe bowl and allow it to cool slightly before mixing.
- Mix sugars: Whisk in granulated sugar and brown sugar into the melted butter until the mixture is smooth and well combined.
- Add eggs and vanilla: Incorporate the eggs one at a time along with the vanilla extract, mixing until the batter turns glossy and slightly thickened.
- Add dry ingredients: Gently fold in the unsweetened cocoa powder, all-purpose flour, and salt just until combined, taking care not to overmix to keep the brownies tender.
- Layer batter and toppings: Pour half of the brownie batter into the prepared baking pan. Drop spoonfuls of creamy peanut butter and marshmallow fluff over the batter, then swirl gently with a knife or skewer to create a marbled effect.
- Add remaining batter and swirl: Pour the remaining brownie batter on top and optionally add more peanut butter and marshmallow fluff dollops to swirl again for a defined pattern.
- Bake: Bake in the preheated oven for 28–32 minutes or until a toothpick inserted in the center comes out with a few moist crumbs but not wet batter.
- Cool and serve: Allow the brownies to cool completely in the pan before slicing into 16 squares and serving.
Notes
- Use parchment paper to easily lift out the brownies for clean slicing.
- Do not overmix the batter to avoid tough brownies.
- Swirling the peanut butter and fluff creates a beautiful marbled effect and blends flavors.
- Chocolate chips are optional but add extra texture and richness.
- Store leftovers in an airtight container at room temperature for up to 3 days.
