Ingredients for Cosmic Brownies

If you want to make a batch of nostalgic goodness, here is everything you need! These homemade cosmic brownies use a lot of pantry staples to make your life a little easier. If you’re looking for measurements then check out the recipe card below!

Chopped Dark Chocolate: Gives the cosmic brownies rich, deep flavor. If you don’t want to use dark chocolate, you can also substitute it with semisweet or milk chocolate.

Unsalted Butter: Butter adds richness and flavor to the brownies. If you don’t have unsalted butter, you can use salted butter instead, but be sure to reduce the amount of salt you use in the recipe.

Granulated Sugar: A must-add for sweet, delicious cosmic brownies!

Dark Brown Sugar: Brown sugar adds a deep sweetness to the brownies. If you don’t have dark brown sugar, you can use light brown sugar instead, but the flavor and texture of the brownies may be slightly different.

Eggs: Eggs provide structure and moisture to the brownies.

Salt: Just a pinch to balance out sweetness and enhance all of the flavors!

Cornstarch: Cornstarch helps to thicken the batter and create a fudgy texture.

Baking Powder: Baking powder helps the cosmic brownies to rise and creates a lighter texture.

Cocoa Powder: Adds that delicious, signature chocolate flavor to each bite!

Flour: All-purpose flour works great to provide structure and texture to the brownies.

Ganache

Semi-Sweet Chocolate Chips: Give the ganache its chocolatey flavor!

Unsalted Butter: Adds a smooth texture and rich flavor to the chocolate ganache that’s simply out of this world.

Heavy Cream: You can’t go wrong with heavy cream! It adds richness and depth of flavor that’s simply heavenly.

Rainbow Sprinkles: These add a playful touch to your cosmic brownies. They’re the perfect way to add a pop of color! I used these sprinkles from Amazon, but feel free to decorate them however you like!

Transfer Batter to Pan, Bake: Add the brownie batter to the prepared pan and smooth with a spatula. Bake for 40-45 minutes, until a toothpick comes out clean from the center.

Cool: Let the brownies cool completely.

Ganache

Heat Ingredients: Gently heat the chocolate, butter, and cream in 20 second intervals in the microwave until steaming. Whisk together until smooth. Pour over cooled brownies and smooth over the top. Sprinkle rainbow chips or sprinkles over the ganache before it sets.

Allow to Set: Chill in the fridge for at least an hour before serving.
