Classic Cosmic Brownies: Step-by-Step Guide

Step 1: Preheat Your Oven

Begin by preheating your oven to 350°F (175°C). Grease and line the baking pan with parchment paper, leaving some overhang for easy removal later.

Step 2: Melt the Chocolate

In a double boiler or microwave-safe bowl, combine the chopped dark chocolate and melted butter. Heat gently until the chocolate is fully melted and smooth, stirring occasionally.

Step 3: Mix the Sugars

In a large mixing bowl, whisk together the granulated sugar and dark brown sugar. Once combined, add the melted chocolate mixture and stir until well incorporated.

Step 4: Add the Eggs and Vanilla

Crack the eggs into the sugar-chocolate mixture, one at a time, whisking well after each addition. This will help to create a smooth, glossy batter. Add in a splash of vanilla extract if desired for additional flavor.

Step 5: Combine the Dry Ingredients

In a separate bowl, sift together the salt, cornstarch, baking powder, cocoa powder, and flour. Gradually fold the dry ingredients into the wet mixture using a rubber spatula until just combined, being careful not to overmix.

Step 6: Stir in the Chocolate Chips

Gently fold in the semi-sweet chocolate chips, ensuring they are evenly distributed throughout the batter.

Step 7: Bake the Brownies

Pour the brownie batter into the prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Step 8: Make the Ganache

While the brownies are baking, prepare the chocolate ganache. In a small saucepan, heat the heavy cream until just simmering. Pour over the remaining chopped chocolate and 2 tablespoons of butter in a bowl. Let sit for a couple of minutes, then whisk until smooth and glossy.

Step 9: Cool and Top

Once the brownies have cooled completely, pour the ganache over the top, spreading evenly. Immediately sprinkle with rainbow chips or sprinkles for that iconic Cosmic touch.

Step 10: Cut and Serve

Use the parchment overhang to lift the brownies out of the pan. Cut into squares and enjoy your Classic Cosmic Brownies!

Can I use cocoa powder instead of dark chocolate?

While you can use cocoa powder, it’s best to stick with dark chocolate for that rich flavor and fudgy consistency that makes Classic Cosmic Brownies so special.

What can I substitute for eggs in this recipe?

You can use flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water for each egg) or commercial egg replacers, but this may alter the texture slightly.

Simply substitute the all-purpose flour with a gluten-free flour blend, and ensure all other ingredients are gluten-free as well.
