Copycat Cosmic Brownies

There is something so special to me about creating these copycat recipes that we all have missed or just remember being so delicious from our childhood. I can’t tell you the last time I had an actual cosmic brownie but believe me when I tell you that they were one of my favorite treats as a kid. They’re so unique and unlike any other brownie. Their texture is so fudgy and they’re more dense than fluffy, but it works so well. They’re topped with a smooth chocolate ganache and of course, the most nostalgic part of it all is the little rainbow chips on top.

I hope you all enjoy this recipe as much as I do and that this copycat recipe takes you back to your childhood 🙂

Tips For Making The Most PERFECT Copycat Cosmic Brownie

Because this recipe is super simple, I have all the confidence in the world that you can all achieve the best results. I will however give you a few tips that might help you throughout the process.

This brownie batter will be very thick – don’t be alarmed if as you’re mixing you begin to worry if you’ve done something wrong. At this point in the recipe, it’s best to switch from using a whisk to using a silicone spatula to fold in the dry ingredients. The silicone spatula will also help you spread and flatten the brownie batter into the prepared pan more easily.

Once the brownies have cooled, we can go ahead and pour on our velvety smooth ganache. The ganache is a simple two ingredients, chocolate and heavy cream. It’s important to heat the heavy cream up until it is bubbling to ensure that it’s hot enough to melt our chips. Once you pour the heavy cream over the chips, don’t begin whisking immediately. Give the two ingredients time to get to know each other. As soon as you begin whisking and incorporating air into the ganache, the temperature will decrease which runs the risk of the chocolate chips not having enough time to melt which will inturn lead to a lumpy ganache.

What Do Cosmic Brownies Taste Like?

Cosmic brownies are so dense, rich, and fudgy. The best part is that in this recipe you get to have the taste of the nostalgic cosmic brownies but without all of the added ingredients that are found in the storebought ones.

I think the most unique part about cosmic brownies is as mentioned the dense and chewy texture that simultaneously melts in your mouth. You get a small crunch from the rainbow chips and a smooth texture from the chocolate ganache. I must admit that this recipe is even better than the ones we all know and love.

To alter your cosmic brownie recipe a bit to your liking while still keeping the overall cosmic brownie outcome, try adding some extra vanilla extract, or using a light and airy chocolate frosting instead of chocolate ganache. You can always reuse the base brownie recipe or the ganache recipe separatley for future use too, that’s the best part about making homemade cosmic brownies 🙂

Ingredients

  • 12 Tbsp. unsalted butter, melted

  • 1 cup unsweetened cocoa powder

  • 1/2 cups brown sugar

  • 3/4 cups sugar

  • 3 tsp. vanilla

  • 2 eggs, room temperature

  • 1 1/4 cups all-purpose flour

  • 1/2 tsp. cornstarch

  • 1/4 tsp. salt

  • Chocolate Ganache
  • 1 1/2 cups semi-sweet chocolate chips

  • 1 cup heavy whipping cream

  • 1/2 cup Rainbow Chips

Directions

  • Preheat the oven to 350 degrees and line a 9″ x 13″ pan with parchment paper and grease with nonstick spray. Set aside.
  • In the bowl of a stand mixer fit with the paddle attachment or in a medium-sized mixing bowl, whisk together the melted butter and cocoa powder until smooth.
  • Add in both sugars. Continue to whisk until smooth.
  • Add in the vanilla. Whisk in the eggs one at a time mixing between each addition.
  • Sift in the dry ingredients one at a time; flour, cornstarch, and salt.
  • Use a silicone spatula to fold in the dry ingredients. The batter will be very thick, don’t worry!
  • Pour and spread the brownie batter into the prepared pan evenly distributing it throughout the pan. Bake for 15-20 minutes or until the middle doesn’t jiggle and the edges are firmed.
  • While the brownies cool in their pan, prepare the ganache. Place the chocolate chips in a small bowl.
  • Microwave the heavy cream in a microwave-safe dish until it begins to bubble.
  • Pour the cream over the chocolate, coating it completely. Let sit for a full minute.
  • Whisk the chocolate and cream together until the mixture is smooth and velvety.
  • Once the brownies are completely cooled, pour the ganache over the brownies spreading it evenly to coat.
  • Let the ganache set for about 1 hour in the fridge to set. Once the ganache has set, remove the brownies from the pan and slice them into even rectangles. To make the iconic line in the center of each brownie, place a skewer down the middle to mark halfway through the brownies then use the back of the skewer to drag across the top of the brownies to create the perfect line.
  • Add the sprinkles on top and enjoy!

  1. I made these brownies for my children. They said they were good, but I might have burnt the heavy cream because they said that the ganache had a funny taste. I will make them again, but I will be careful not to overheat the heavy cream.
