Copycat Cosmic Brownies

Copycat Cosmic Brownies topped with a Chocolate Ganache and rainbow sprinkles! Super chocolatey, rich and chewy! Just like your childhood favorite.


Remember these Little Debbie brownies from your childhood? Well I’m bringing them back!

These brownies are amazing and seriously addicting. They taste just like the brownies you love. These Copycat Cosmic Brownies are super dense, chocolately with a thick layer of chocolate ganache on top!


These have to be my favorite brownie yet. They are so rich and dense with the perfect amount of chewiness. This recipe uses less flour which helps with the chewiness and substitutes some brown sugar for extra moisture.


I used the same Chocolate Ganache from my Flourless Chocolate Cake. If it ain’t broke don’t fix it right?

The ganache is super easy to whip up. Just chocolate and heavy cream melted and poured on top.  Spread the ganache on top of the brownies and place in the fridge to allow it to set.


I made a special trip for these colorful sprinkles. You can always substitute mini M & M’s or rainbow sprinkles. They aren’t the same thing without the burst of color!


These homemade Cosmic Brownies are so much better than store-bought! Pour yourself a cold glass of milk and enjoy!
