These vegan cosmic brownies are just like the Little Debbie Cosmic Brownies. But these are plant-based and even tastier! They have a rich, fudgy brownie layer topped with chocolate ganache and rainbow candy chips.

Everyone loves these brownies! I especially like making them for get togethers or birthdays since they have such a fun and festive look.
These vegan cosmic brownies are ridiculously good! The brownie layer is super rich and also has chocolate chips in it. Then there’s the smooth layer of chocolate ganache. Top it all off with those rainbow chips that I still can’t believe are vegan!

Variations and Substitutions
- I love using the rainbow candy chips as the topping. But you can also use any kind of vegan-friendly colorful sprinkles you’d like.
- If you can’t find vegan cream, you can substitute with vegan butter. The chocolate ganache may be less glossy and a bit thicker. But it will still work!
How To Make Vegan Cosmic Brownies
Step 1: Mix together the ground flax and the water to make flax eggs. Set aside for about 5 minutes to thicken.
Step 2: Preheat the oven to 350℉. Prepare an 8" x 8" baking dish by cutting 2 pieces of parchment paper and laying them in the dish like a "t". This makes it super easy to take the brownies out of the pan to cut.

Step 3: In a medium mixing bowl, microwave the vegan butter for about 45 seconds. Whisk the melted butter with sugar, unsweetened cocoa powder, and vanilla extract. Make sure there aren't any lumps. Stir in the flax eggs.

Step 4: Stir in the flour, salt and the baking powder until just combined. Fold in the chocolate chips with a rubber scraper.

Step 5: Pour the brownie batter into the prepared dish and bake for about 35-40 minutes.

Step 6: Take the brownies out of the oven and cool in the pan for about 20-30 minutes or so. I like to put the pan of brownies on top of a cooling rack. You want to make sure the brownies still aren't hot.

Step 7: Next, make the ganache. Place the chocolate chips in a bowl and set aside. Heat the vegan cream in the microwave for about a minute or until very hot. Pour the cream over the chocolate chips and let sit for 3 minutes. Then, stir the mixture until it gets nice and glossy. Stir in the vanilla extract.

Step 8: Slowly pour the chocolate ganache over the brownies in an even layer. Place in the fridge until cooled and set, about 30 minutes. After about 10 minutes in the fridge, sprinkle the rainbow candy chips on top of the ganache. I don't sprinkle them right away because the ganache will be a little thin and the candy chips will sink a bit.

Step 9: Once completely cooled, use the parchment paper to lift the brownies out of the pan. Cut with a sharp knife and serve.

Expert Tips
- I like to let the mixture of flax and water sit for about 5 minutes to make sure it's thickened up.
- Do not overmix the batter.
- The amount of baking time can depend on the type of pan. Brownies made in glass pans take a few minutes more to cook than if they were baked in metal pans.
- Let the ganache covered brownies cool in the fridge for around 10 minutes before adding the candy chips (or sprinkles). If you add them right away, they'll sink a bit. Letting the ganache cool for about 10 minutes will thicken it up so the candies stay on top.
Recipe and Storage FAQs
For the best texture, I like to store these brownies in the fridge in an airtight container for up to 5 days.
I use Bakers Choice Rainbow Candy Chips which are labeled vegan. I’ve ordered mine from Amazon as I haven’t seen them in stores yet.
