Homemade Cosmic Brownies Recipe (2024)

My kids love the Little Debbie Cosmic Brownies you can get at the supermarket and this copycat recipe couldn't be closer to the real thing! These Cosmic Brownies have a layer of rich chocolate ganache and are covered in colorful sprinkles just like the originals.

Homemade Cosmic Brownies

These homemade Cosmic Brownies are a dark, dense and very rich brownie. I think it is the chocolate ganache that really makes them taste like the real thing!

Cosmic Brownie Ingredients:

These copycat cosmic brownies mix up like a pretty normal brownie recipewith a couple of exceptions, the addition of cornstarch gives it a little bit more of a fudge-like texture, which is what we are going for with these.

Also, the baking powder instead of baking soda helps to add to the fudge-like texture, the brownies rise just a little bit differently.

Other than that, all the ingredients are pretty similar to any other brownie recipe!

Recipe Tips:

Start this recipe off by making your brownie batter and getting your brownies in the oven first. Once you’ve done that, you can whip up the ganache and have it ready to pour over the brownies right when they come out! Once the ganache has set, then you are ready to dig in!

To get the best results with this cosmic brownie recipe, having a good brownie pan helps a lot. Here’s one that we recommend:

Wilton Brownie Bar Pan

12 cavities for a dozen, snack-size brownies with smooth sides and crisp edges
You can easily customize your brownies, adding different toppers to each treat – nuts, candies and more
The non-stick coating makes it easy to remove the treats from the pan
If you like the edge pieces of the brownie pan then you will love to bake individual brownies and other baked treats in the Wilton brownie bar pan

Homemade Cosmic Brownies Recipe

4.50 / 5 ( 14 Reviews )

Ingredients

Brownies:

1¼ cup all-purpose flour
¾ cup unsweetened cocoa powder
1 cup sugar
⅔ cup brown sugar
¾ cup butter, melted 1½ sticks
2 eggs
3 tbsp. milk
½ tsp. baking powder
1 tbsp. cornstarch
pinch of salt
2 tsp. vanilla extract

Fudge Ganache:

1 c. semi-sweet chocolate chips
½ c. milk chocolate chips
½ c. heavy cream

Instructions

Preheat oven to 350°F/175°C. Lightly grease a 9x13 baking dish, set aside.
In the bowl or a stand mixer, beat melted butter, sugars and vanilla until light and fluffy, about 2 minutes. Add eggs, one at a time, mixing until mixed.
In a medium size mixing bowl whisk together flour, cocoa powder, baking powder, cornstarch, and salt. With mixing speed on low, alternate adding dry ingredients and milk. Mix just until combined.
Remove bowl from stand and pour batter into prepared pan. The batter will be thick, so using a rubber spatula, spread into an even layer. Place in oven and bake for 18-25 minutes. The brownies will be done, so do not over-bake or you will have dry brownies! Remove from oven and allow to cool in the pan.
Meanwhile to prepare the ganache, in a 2 cup glass measuring cup, combine chocolate chips and heavy cream. Microwave for one minute, stir, then repeat. Stir chocolate until all of the chips are melted and it becomes smooth. Beat for 1 minute and then pour over the top of the brownies. Spread evenly and sprinkle with desired toppings. Serve warm or cold.
