Marshmallow Brownies
Chewy, fudgy chocolate brownies filled with pockets of gooey marshmallow fluff.
Ingredients
¾ cup (170 g) unsalted butter, melted and slightly cooled
1 cup (200 g) granulated sugar
2 teaspoons vanilla extract
2 large eggs
4 oz (112 g) semisweet chocolate, melted
1 cup (125 g) all-purpose flour
⅔ cup (53 g) unsweetened cocoa powder
¼ teaspoon salt
1 cup marshmallow fluff
How To Make
Preheat the oven to 350°F (180°C). Grease and line an 8-inch square pan with parchment paper.
Beat the melted butter and sugar until thoroughly combined. Add vanilla, then beat in the eggs one at a time.
Mix in the melted chocolate, scraping the bowl as needed.
Sift in the flour, cocoa powder, and salt. Gently fold until no dry streaks remain.
Spread slightly more than half the brownie batter in the pan. Add dollops of marshmallow fluff, followed by the remaining batter.
Gently spread the top; some visible marshmallow is fine.
Bake for about 35 minutes, until the top is set and a toothpick has no wet batter.
Cool completely in the pan before lifting out and slicing into nine brownies.
