Tessa's Recipe Rundown...
Taste: These homemade Cosmic Brownies have a much better chocolate flavor than the store-bought ones! No weird artificial flavors here.
Texture: Ultra rich, fudgy, and chewy. So good.
Ease: Very easy!! Have a batch of these made in just over an hour.
Appearance: I think they look pretty darn similar to the store-bought version, if not more mouthwatering.
Pros: Super fun copycat recipe that’s so much better when homemade.
Cons: Although these are not laden with hydrogenated oils and preservatives like the purchased kind, they still aren’t exactly health food.
Would I make this again? Absolutely!
When I was in elementary school anytime I’d bring a sack lunch it was basically the same exact thing every time. I always ate a peanut butter sandwich, I didn’t even like jelly necessarily. There’d usually be some other element in my lunch bag but I’d ALWAYS request my mom add in a Little Debbie brownie. Before Cosmic Brownies came into existence, it was just the Little Debbie brownies with the nuts on top. I would always pick off all the nuts. In my child mind, nuts shouldn’t be part of any dessert. Gross. So you could imagine my excitement when I spotted Cosmic Brownies on the shelf at the store. Candy > Nuts any day! I freakin’ loved those Cosmic Brownies.
I had forgotten all about them until one of my favorite blogs, Averie Cooks, posted a recipe for Homemade Little Debbie Cosmic Brownies. Immediately my mouth started watering. The idea of making homemade Cosmic Brownies from scratch sounded amazing, and I knew I had to make my own version! I got started making the most fudgy, chewy brownies I could, using everything I learned from my Ultimate Brownie Guide. I even managed to find the exact candies Little Debbie tops the brownies with, they’re Wilton Rainbow Chip Crunch and I found them at Michael’s, but they’re also available on Amazon for cheaper.
I think I managed to create something that will evoke all those childhood memories of snacking on those little plastic-wrapped store-bought brownies, but these babies are SO much better! Real and satisfying chocolate taste with no crazy artificial ingredients. There is a small amount of both cornstarch and corn syrup in this recipe to help make the brownies super chewy, feel free to omit the corn syrup or use golden syrup if you prefer!

For the brownies
- 10 tablespoons (5 ounces or 142 grams) unsalted butter
- 1 cup granulated sugar
- 1/3 cup packed light brown sugar
- 3/4 cup plus 2 tablespoons (3.12 ounces or 88.4 grams) unsweetened cocoa powder, sifted
- 1/2 teaspoon vanilla extract
- 2 large eggs plus 1 egg yolk
- 1 tablespoon corn syrup
- 2/3 cup (3 ounces or 85 grams) all-purpose flour
- 1 tablespoon cornstarch
- 1/4 teaspoon salt
For the frosting
- 1 1/2 cups semisweet chocolate chips
- 1/2 cup heavy cream
- Wilton Rainbow Chip Crunch or mini M&M's, sprinkles, or other candy
To make the brownies:
Preheat the oven to 350°F. Line an 8-by-8-inch baking pan with foil and spray with cooking spray.
In a large microwave-safe bowl, melt the butter for about 90 seconds on high power. Stir in the granulated sugar, brown sugar, and cocoa powder. If still very hot, let cool slightly before adding in the vanilla, eggs and egg yolk, and corn syrup. Stir until very well combined. Add in the flour, cornstarch, and salt and stir until just combined. Pour into the prepared pan and bake for 25 minutes. Let cool completely in the pan.
To make the frosting:
Place the cream in a small microwave-safe bowl and microwave on high for 1 minute. Add in the chocolate chips. Let stand for 3 minutes before stirring until smooth. Pour over the cooled brownies and smooth evenly. Sprinkle with the Rainbow Crunch Chips. Refrigerate for 1 to 2 hours, or until the frosting is set, before cutting.
Brownies can be stored in an airtight container for 4 days at room temperature and for 1 week in the fridge. Brownies are best served chilled.
