Cosmic Brownie Cookies are rich, chewy, and really fudgy! Covered with a thick chocolate ganache coating and colorful candy on top, this recipe is a remarkable Crumbl Cookies copycat!
Fudgy Cosmic Brownie Cookies
Our Cosmic Brownie Cookies recipe is inspired both by the renowned Crumbl Cookies and by Little Debbie Cosmic Brownies, but even better than the bakery-bought item or lunch box treat!
These fudgy, chewy, deliciously dense desserts are so easy to make; it takes only 10 minutes to prepare the brownie batter and 11 more minutes to bake.
The 2 ingredient ganache comes together quickly by melting chocolate with heavy cream in the microwave (no cooking needed), then it hardens into the perfect fudge frosting that holds the colorful rainbow candy in place.
