Ingredients used to make Copycat Cosmic Brownies:

For the brownies

• Granulated sugar 
• Brown sugar 
• Unsweetened cocoa powder 
• Vanilla extract

For the ganache

How to make these Copycat Cosmic Brownies:

• Prep. Preheat the oven to 350°F and line an 8X8-inch baking pan with parchment paper. Make sure to leave a bit of parchment paper hanging over the sides of the pan. 

• Make the brownie batter. Whisk together the butter, vegetable oil, sugars, cocoa powder, vanilla, egg, egg yolks, and corn syrup in a large mixing bowl until smooth. Whisk in the dry ingredients, flour, cornstarch, and salt until smooth. 

• Bake. Pour batter into the prepared pan and bake for 20-25 minutes or until a toothpick inserted in the center comes out mostly clean. 
• Cool. Remove the brownies from the oven and allow them to cool completely in the pan. 

• Make the ganache. While the brownies are cooling, heat the heavy cream until it’s almost boiling and pour it over the chocolate chips. Let the mixture sit for a couple of minutes before whisking it until smooth. Whisk in the corn syrup. 

• Frost the brownies. Use the parchment paper to lift the fully cooled brownies from the pan. Spread the ganache over the brownies and top with rainbow sprinkles.
