Ingredients
Scale
- 1/2 cup unsalted butter, melted and slightly cooled
- 1 cup granulated white sugar
- 2 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- 1/3 cup high-quality unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 1/4 teaspoon baking powder
- 1/2 cup semi-sweet chocolate chips
- 2 cups mini marshmallows
- Optional: Chocolate syrup for drizzling
Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving a slight overhang on the sides for easy removal later. Lightly grease the parchment paper with butter or non-stick cooking spray to ensure the marshmallows don’t stick to the edges.
- In a large mixing bowl, whisk the melted butter and granulated sugar together until well combined. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. This creates the foundation for that perfect chewy texture.
- Sift the cocoa powder, all-purpose flour, salt, and baking powder directly into the wet mixture. Use a spatula to gently fold the ingredients together until just combined. Do not overmix, as this can make the brownies tough. Fold in the chocolate chips for extra pockets of melted chocolate.
- Pour the batter into the prepared baking pan and spread it evenly with a spatula. Place the pan in the center rack of the oven and bake for 20 to 22 minutes. The center should be slightly set but still a bit soft to the touch.
- Remove the pan from the oven and quickly sprinkle the mini marshmallows evenly over the top of the hot brownies. Return the pan to the oven for another 5 to 8 minutes, or until the marshmallows have puffed up and turned a light golden brown. For a more charred look, you can briefly turn on the broiler for 30 seconds, watching very closely to prevent burning.
- Place the pan on a wire rack and let the brownies cool completely. This is the hardest part, but cooling allows the fudgy center to set and the marshmallows to firm up. Once cool, lift the parchment paper to remove the brownies from the pan and slice them into 16 even squares using a greased knife.
- Cook Time: 45 minutes
