An easy, made-from-scratch Cosmic Brownie recipe! These chewy, chocolate-frosted and colorfully sprinkled treats are much better than store-bought and made without all of the preservatives. These fun family treats are a breeze to make!
So, more brownies today. You’re not tired of them yet, are you?
I never really had Cosmic Brownies as a kid (we were a Swiss Roll kinda family) and didn’t actually taste one until I was much older. They weren’t bad, but I knew that if we could eliminate some of the processed taste, they could be so much better.
I found the candy coated chips for the topping in my local grocery store (they were actually the inspiration for these copycat Cosmic Brownies); you should be able to find them in the cake decorating aisle where the other sprinkles are stored, but you can also buy them on Amazon (affiliate).
I found those chips and starting developing these Cosmic Brownies right around the same time that I made approximately 653 batches of brownies developing my Easy Brownies from Scratch recipe.
This recipe is a little different, though.
I didn’t want to use either my best ever brownies or my easier from-scratch recipe, because while those brownies are amazingly ridiculously good as stand-alone, I thought they might be too much for this recipe. Too rich and chocolaty for the chewy store-bought brownie I was trying to mimic.
Also, the other recipes had a nice crinkly top that just flaked up too much when I tried to pour/spread frosting over it.
This recipe mimics those easy from-scratch brownies, just toned down a few notches to better align with the taste of their packaged counterparts.
The smooth chocolate frosting is made of a combination of both semisweet and milk chocolate chips (to keep it from being overly sweet or rich) and takes only a few minutes to melt together.
An easy made-from-scratch Cosmic Brownie recipe! Better than store-bought and without all of the preservatives, these fun family treats are a breeze to make!
- 12 Tablespoons butter cut into Tablespoon-sized pieces 170g
- 3/4 cup natural cocoa powder 75g
- 1 cup granulated sugar 200g
- ½ cup brown sugar 100g
- 1 teaspoon vanilla extract 5ml
- 2 large eggs + 1 large egg yolk lightly beaten
- 1 ¼ cup all-purpose four 145g
- 1 teaspoon cornstarch
- 1/2 teaspoon salt
- 1 cup semisweet chips 175g
- ½ cup milk chocolate chips 88g
- ⅓ cup heavy cream 79ml
- 1 teaspoon vanilla extract 5ml
- 1/8 teaspoon salt
- 1/4 cup candy coated chips
Prepare a 13x9 pan by lightly greasing and flouring, or line with parchment paper. Preheat oven to 350F.
Place butter in a large, microwave-safe bowl, and microwave until completely melted.
Stir in cocoa powder.
Add sugars, and stir well.
Add eggs, one at a time, stirring well after each addition.
Stir in vanilla extract. Set aside.
In a separate, medium-sized bowl, whisk together flour, cornstarch (cornflour for UK), and salt.
Gradually stir dry ingredients into wet until completely combined.
Evenly spread into prepared pan and bake on 350F (177C) and bake for 16-18 minutes. Allow to cool completely before frosting.
Combine chocolate chips and heavy cream in a medium-sized saucepan over medium-low heat. Stir well until chocolate is completely melted and mixture is smooth.
Remove from heat and stir in vanilla extract and salt. Allow to cool 5-10 minutes before proceeding.
Evenly pour frosting over brownies, using a spatula to spread evenly.
Immediately sprinkle candy chips over top. Allow frosting to harden (about 1 hour) before cutting and eating (this can be sped up if you place the brownies in the refrigerator for about 15 minutes).
