The combination of rich, fudgy brownies and the sweet, gooey swirl of peanut butter and marshmallow fluff makes each bite a heavenly experience. The best part? They’re incredibly easy to make—just a few ingredients and a little swirling, and you’re all set! These brownies are perfect for any occasion, whether you’re hosting a party, sharing with friends, or treating yourself to something sweet. Plus, they deliver both nostalgia and flavor in every bite.

Ingredients Overview

For these Fluffernutter Brownies, you’ll need just a handful of ingredients that come together to create a flavor explosion. The base starts with a brownie mix for ease and convenience, but you can make your own brownies from scratch if you prefer. The magic happens when you add the peanut butter and marshmallow fluff, creating those signature swirls that make these brownies so special. It’s a classic combination with a modern twist, offering the perfect mix of gooey and chewy textures.

How to Make the Recipe

Step 1: Preheat your oven to 350°F and line a 9×9-inch baking pan with parchment paper on all sides. Set aside.

Step 2: Prepare the brownie mix according to the package instructions. Pour the batter into the prepared pan and spread it evenly using a rubber spatula.

Step 3: Microwave the peanut butter in a microwave-safe bowl for about 30 seconds or until it’s melted. In another microwave-safe bowl, microwave the marshmallow fluff for about 20 seconds.

Step 4: Drop dollops of the melted peanut butter and marshmallow fluff onto the brownie batter in a checkerboard fashion. Don’t worry about precision here—it’s all about creating beautiful swirls!

Step 5: Use a butter knife to gently swirl the peanut butter and fluff into the brownies. Be careful not to over-swish, as you want to preserve those distinct ribbons of fluff and peanut butter.

Step 6: Bake the brownies for 20 to 30 minutes, or until the edges are set and a knife inserted into the center comes out mostly clean. You want to keep that gooey center intact for the ultimate fudgy texture.

Step 7: Allow the brownies to cool completely before slicing them into 16 small brownies or 9 larger pieces. Enjoy the perfect blend of peanut butter and fluff with every bite!

Tips for the Best Recipe

  • Use a high-quality brownie mix for the best texture and flavor, or if you’re feeling adventurous, make homemade brownies from scratch.
  • Don’t over-swish the peanut butter and fluff. A light swirl is enough to create those signature marbled patterns, while leaving the distinct ribbons of peanut butter and fluff visible.
  • Underbake the brownies slightly to achieve that perfect, fudgy center. You’ll know they’re done when the edges are set, and the center is just slightly gooey.

Variations to Try

  • For an extra twist, add chocolate chips to the brownie batter before baking for a chocolate-peanut butter combination.
  • Want to enhance the flavor even further? Drizzle melted chocolate over the cooled brownies for a finishing touch that adds richness.
