Recipe Information
Ingredients
- 113 grams unsalted butter
- 200 grams light brown sugar
- 50 grams granulated sugar
- 200 grams creamy peanut butter
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 180 grams all-purpose flour
- 1 teaspoon baking powder
- 0.5 teaspoon salt
- 150 grams marshmallow fluff
- 120 grams semi-sweet chocolate chips
Instructions
Preheat your oven to 350°F (175°C) and line a 9x9-inch (23x23 cm) baking pan with parchment paper, leaving an overhang for easy removal.
In a medium saucepan, melt the butter over medium heat. Once melted, remove from heat and whisk in the light brown sugar and granulated sugar until combined and smooth. Let it cool slightly for about 2-3 minutes.
Stir in the peanut butter until fully incorporated, followed by the eggs and vanilla extract. Mix until smooth.
In a separate mixing bowl, sift together the all-purpose flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix.
Spread half of the batter evenly into the prepared baking pan. Use an offset spatula or a spoon to smooth the surface.
Spoon dollops of marshmallow fluff evenly over the batter layer. Use a knife or spatula to gently swirl the fluff into the batter without completely mixing it in.
Sprinkle the semi-sweet chocolate chips evenly across the marshmallow layer.
Drop the remaining batter over the top in spoonfuls, and gently spread it out to cover most of the surface. It’s okay if there are a few gaps where the marshmallow peeks through.
Bake in the preheated oven for 22-25 minutes, or until the top is golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
Allow the bars to cool completely in the pan before lifting them out using the parchment paper overhang. Slice into 16 squares and enjoy!
