How to Make Fluffer Nutter Brownies
Get ready for a taste of pure bliss with these incredibly easy Fluffer Nutter Brownies! In under 60 minutes, you’ll whip up a batch of fudgy brownies swirled with decadent peanut butter and fluffy marshmallow. The magic lies in the no-bake approach and the perfect balance of rich chocolate, salty peanut butter, and sweet, airy marshmallow, making them a truly satisfying treat.
Step-by-Step Instructions
- Prepare Your Pan: Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides. This will make it incredibly easy to lift the brownies out once they’re set. Lightly grease the parchment paper as well.
- Melt the Butter: In a large microwave-safe bowl, melt the 1 cup of unsalted butter. This is the base for our rich brownie mixture.
- Combine Wet Ingredients: To the melted butter, add the 2 cups of granulated sugar and whisk until well combined. Then, beat in the 4 large eggs, one at a time, ensuring each is fully incorporated before adding the next. Stir in the 1 teaspoon of vanilla extract for that classic brownie flavor.
- Add Dry Ingredients: In a separate medium bowl, whisk together the 1 cup of all-purpose flour, ½ cup of unsweetened cocoa powder, ½ teaspoon of baking powder, and ¼ teaspoon of salt. This ensures your dry ingredients are evenly distributed, preventing pockets of flour or leavening agents.
- Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix, as this can lead to tough brownies. A few streaks of flour are acceptable.
- Incorporate Peanut Butter and Fluff: In a small bowl, gently warm the ¾ cup of creamy peanut butter and ½ cup of marshmallow fluff in the microwave for about 20-30 seconds until slightly softened. This will make them easier to swirl. Spoon dollops of this peanut butter and marshmallow mixture over the brownie batter.
- Swirl the Dreamy Layers: Using a knife or a skewer, gently swirl the peanut butter and marshmallow fluff into the brownie batter. Don’t over-swirl; you want distinct pockets and ribbons of flavor.
- Add Chocolate Chips (Optional): If you like an extra burst of chocolate, sprinkle the ½ cup of chopped semi-sweet chocolate chips over the top of the batter and gently swirl them in as well.
- Chill to Set: Cover the pan tightly with plastic wrap and refrigerate for at least 3-4 hours, or until the brownies are firm and set. This no-bake method allows the flavors to meld beautifully and the texture to become perfectly fudgy.
- Cut and Serve: Once the brownies are firm, use the parchment paper overhang to lift the entire slab out of the pan. Place it on a cutting board and cut into desired squares. For an extra decadent touch, you can drizzle with additional warmed peanut butter and marshmallow fluff before serving.

- Refrigeration: Store leftover brownies in an airtight container in the refrigerator for up to 5 days. The cold will help maintain their fudgy texture.
- Freezing: For longer storage, wrap individual brownies or the entire pan tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months.
- Reheating (Optional): While these brownies are best enjoyed chilled or at room temperature, if you prefer a slightly warmer, gooier texture, you can gently warm individual squares in the microwave for 10-15 seconds. Be careful not to overheat, as they can become too soft. Thaw frozen brownies in the refrigerator overnight before serving or enjoying.
