These cosmic brownies are everything I remember… just better.
Fudgy centers. Thick chocolate ganache. Rainbow chips.
I know so many millennials were obsessed with the boxed ones as a kid… and honestly, I wasn’t (oatmeal crème pies were my thing).
But homemade? It’s a different level.
Save this one because you’ll want to make them again.
