Indulge in the nostalgia of childhood with these homemade cosmic brownies. They are fudgy, rich, and topped with colorful sprinkles, just like the classic store-bought version.
Instructions: Preheat your oven to 350F 175C and grease a 9x13-inch baking pan. In a microwave-safe bowl, melt the butter in 20-second intervals until fully melted. In a separate large mixing bowl, whisk together the sugar, eggs, and vanilla extract until well combined. Stir the melted butter into the sugar mixture until smooth and well incorporated. Sift the cocoa powder, flour, and salt into the wet ingredients, and gently fold until just combined. Be careful not to overmix. Fold in the semisweet chocolate chips. Pour the brownie batter into the greased baking pan and spread it evenly. Bake in the preheated oven for 20-25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Do not overbake. Remove the brownies from the oven and immediately sprinkle the rainbow sprinkles on top while they are still warm, gently pressing them into the surface. Allow the brownies to cool completely in the pan on a wire rack before cutting them into squares. Enjoy your homemade cosmic brownies!
