Description

These Homemade Cosmic Brownies® are an upgrade from the boxed brownies you may have had as a child. This from-scratch version delivers all the joy with a richer, deeper chocolate flavor. And the best part? It's only slightly more effort than reaching for the box. With one bowl and about one hour, you can be rewarded with ultra-fudgy brownies, a luscious layer of silky ganache, and a shower of vibrant sprinkles for that signature cosmic charm. Whether you're baking for a potluck, picnic, or just because, these copycat cosmic brownies guarantee nostalgic happiness.
