These Fluffernutter Brownies are a decadent treat combining rich chocolate brownies with creamy peanut butter and sweet marshmallow fluff swirled on top. The brownies have a fudgy texture thanks to melted butter and chocolate, while the peanut butter and marshmallow create a luscious, nostalgic fluffernutter flavor that’s perfect for dessert or any time you crave something indulgent.

Ingredients

Scale

Dry Ingredients

  • 1 ⅓ cups (167.3 g) regular unsweetened cocoa powder
  • 1 cup (125 g) all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon kosher salt
  • 1 teaspoon espresso powder

Wet Ingredients

  • 1 cup (2 sticks / 227 g) unsalted butter, room temperature
  • 2 cups (400 g) granulated sugar
  • 1 cup (168 g) semi-sweet chocolate chips
  • 1 tablespoon vanilla extract
  • 4 large eggs, room temperature

Toppings

  • ¾ cup (193.5 g) creamy peanut butter
  • 1 cup (96 g) marshmallow fluff

Instructions

  1. Preheat oven and prepare pan: Preheat the oven to 350°F (175°C). Line a 9×13-inch ceramic baking dish with parchment paper to prevent sticking and for easy removal.
  2. Whisk dry ingredients: In a large bowl, combine the cocoa powder, all-purpose flour, baking powder, kosher salt, and espresso powder. Whisk together thoroughly and set aside.
  3. Cook butter with sugar: In a large saucepan over medium heat, add the unsalted butter and granulated sugar. Stir occasionally until the butter melts. Then bring the mixture to a low boil and cook for about 2 minutes, or until it reaches 230°F (110°C) on an instant-read thermometer.
  4. Incorporate chocolate and vanilla: Remove the saucepan from heat. Stir in the semi-sweet chocolate chips and vanilla extract until the chocolate melts completely. The mixture may look grainy but that’s normal. Let it cool for about 10 minutes.
  5. Add eggs: Add the room temperature eggs one at a time to the chocolate mixture, stirring constantly to create a smooth batter.
  6. Combine dry ingredients with chocolate mixture: Add the whisked dry ingredients to the chocolate mixture. Stir until just combined; the batter will be thick.
  7. Layer the batter: Spread half of the brownie batter evenly into the prepared baking dish.
  8. Add peanut butter and marshmallow fluff: Spread the creamy peanut butter over the layer of batter. Using a piping bag or a plastic bag with the corner cut off, pipe the marshmallow fluff evenly on top of the peanut butter layer.
  9. Top with remaining batter: Spread the remaining brownie batter over the marshmallow fluff layer to cover it fully.
  10. Bake the brownies: Place the baking dish in the preheated oven and bake for 28 to 30 minutes. The brownies are done when a toothpick inserted near the center comes out with a few moist crumbs but not wet batter.
  11. Cool and serve: Remove the brownies from the oven and allow them to cool completely in the baking dish before cutting into squares and serving.

Notes

  • For best results, ensure butter and eggs are at room temperature before starting.
  • Using an instant-read thermometer helps achieve the perfect butter-sugar temperature for fudgy brownies.
  • The espresso powder enhances the chocolate flavor but can be omitted if desired.
  • Parchment paper makes it much easier to lift the brownies out of the dish for cutting.
  • Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
