Healthier homemade Cosmic Brownies! Fudgy flourless brownie, chocolate ganache, and iconic rainbow sprinkles. Childhood fun meets grown up decadence!

If you want to scroll right on past the chatter and get straight to the sprinkle-topped chocolate-frosted brownie part of this post, I will not blame you one bit. Words really cannot properly express how much I love this recipe.

Last week Sonya and I were texting recipe ideas back and forth, she said cosmic brownies, I said YES (with many many exclamation points), all other ideas suddenly paled in comparison, and we broke out the rainbow sprinkles.

Looks aside, this recipe is all kinds of fudgy flourless decadence. The brownie base is dense and so rich, made with just 7 ingredients. The chocolate ganache is where decadence truly reaches an all time high, dairy-free made with dark chocolate chips and coconut milk that sets to the perfect cosmic brownie copycat consistency. And the rainbow sprinkles are obviously just for fun, but I will be a little sad if you skip them.

They were gone by the end of the night with high praise from everyone we shared with, so unless you hate chocolate you will love these.

Happy homemade, tiny bit healthier, Vegan Cosmic Brownie baking to you!

Also I am kinda really REALLY obsessed with this video. Maybe my favorite I’ve ever shared. Shoutout to Daniel Peacocke for these cinematographic skills…

Healthier homemade Cosmic Brownies! Fudgy flourless brownie, chocolate ganache, and iconic rainbow sprinkles. Childhood fun meets grown up decadence!




  • 2 flax eggs (2 tbsp ground flax + 6 tbsp warm water)
  • 3/4 cup (185g) runny nut/seed butter
  • 1/4 cup (50g) coconut oil*
  • 1/2 cup (75g) coconut sugar
  • 1 tsp vanilla extract
  • 3/4 cup (70g) cacao powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt


  • 1 cup (160g) chocolate chips
  • 1/3 cup coconut milk
  • Colorful sprinkles for topping**


  1. Preheat the oven to 350ºF.
  2. Whisk together the nut/seed butter, coconut sugar, prepared flax eggs, and vanilla.
  3. Stir in the cacao powder, baking soda, and salt to form a thick batter. If batter seems too dry add 1/4 cup coconut oil or nondairy milk.
  4. Spread into a greased loaf pan.
  5. Bake for 20-25 minutes at 350ºF.
  6. Cool completely (or chill to speed it up) before frosting.
  7. For the ganache, melt the chocolate chips with the coconut milk. Stir until smooth.
  8. Pour/spread on top of cooled brownies. Top with sprinkles. Chill until the ganache is set.
  9. Slice and eat!


*You can use non-dairy milk instead for an oil free option, but the brownies will be drier.

**Or for an all natural sprinkle option, make your own!
