What Are Cosmic Brownies?
If you’ve ever unwrapped a pack of Little Debbie’s Cosmic Brownies, you know they’re no ordinary chocolate treat. These fudgy, chewy brownies are topped with a smooth chocolate ganache and sprinkled with rainbow candy-coated chocolate chips, making them a colorful, nostalgic favorite.
Unlike classic brownies that have a crinkly top, Cosmic Brownies boast a dense, almost truffle-like texture, giving them that signature soft and rich bite. They were originally introduced in the ’90s as a kid-friendly snack, but their deliciously gooey consistency and deep chocolate flavor have made them a hit with dessert lovers of all ages.
What Makes Them Special?
- Ultra-fudgy texture – No cakey brownies here! These stay dense, chewy, and moist.
- Glossy chocolate ganache – A creamy, velvety layer of chocolate that enhances every bite.
- Nostalgic appeal – A homemade take on a childhood favorite with better ingredients.
- Customizable toppings – Stick with the classic rainbow sprinkles or switch it up with nuts, white chocolate, or caramel drizzle.
Key Benefits of Homemade Cosmic Brownies
Making homemade Cosmic Brownies isn’t just about recreating a childhood favorite—it’s about crafting a richer, fresher, and more indulgent treat that you can customize to perfection. Here’s why you’ll love baking them from scratch:
1. Superior Taste and Texture
Store-bought Cosmic Brownies are delicious, but nothing beats the depth of flavor in a homemade version. Using high-quality cocoa powder, real butter, and pure vanilla extract results in a brownie that’s ultra-fudgy, dense, and perfectly chewy—with none of the artificial aftertaste.
2. No Preservatives or Unwanted Additives
Many packaged desserts contain preservatives and artificial ingredients to extend shelf life. When you make your own, you control every ingredient, ensuring a cleaner, better-tasting dessert without unnecessary fillers.
3. Customizable for Any Occasion
Want to switch things up? Here are a few fun ways to personalize your Cosmic Brownies:
- Swap the topping – Try mini peanut butter cups, caramel drizzle, or chopped nuts instead of rainbow chips.
- Make them gluten-free – Use a 1:1 gluten-free flour blend for the same chewy texture.
- Boost the chocolate flavor – Add espresso powder to enhance the richness.
4. Budget-Friendly & Easy to Make
A batch of homemade Cosmic Brownies costs less than constantly buying packaged ones, and they come together in just a few simple steps. Plus, you can make a double batch and freeze them for later!
5. Perfect for Any Dessert Lover
Whether you’re making them for kids, parties, bake sales, or just a personal treat, these brownies always impress. They’re the perfect balance of nostalgic and gourmet, making them a dessert that everyone—young and old—will love.
Ingredients for Cosmic Brownies
Here’s everything you’ll need to bake your Cosmic Brownies to perfection. Don’t worry, it’s simple—these basic ingredients will come together to create a dessert you’ll love!
For the Brownie Batter
- 1/2 cup (115g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 cup (45g) unsweetened cocoa powder
- 1/2 cup (60g) all-purpose flour
- 1/4 tsp salt
- 1/4 tsp baking powder
- 1/2 cup (90g) semi-sweet chocolate chips (for a richer flavor)
- 1/4 cup (60ml) whole milk (for extra moisture)
For the Ganache Topping
- 1/2 cup (120ml) heavy cream
- 1 cup (170g) semi-sweet chocolate chips

Pro Tips:
- Butter: For best results, use unsalted butter to have more control over the salt content.
- Cocoa Powder: If you have Dutch-processed cocoa powder, use it—it gives the brownies a smoother, deeper flavor.
- Flour: Make sure to measure the flour correctly—too much flour will result in cakier brownies. Spoon the flour into the measuring cup and level it off.
- Chocolate Chips: Feel free to mix and match with milk chocolate chips for a sweeter topping or dark chocolate chips for a more intense chocolate flavor.
Here’s How to Make Copycat Cosmic Brownies
Making your own Cosmic Brownies is easier than you think! Just follow these simple steps, and you’ll have a batch of chewy, fudgy brownies with that signature chocolate ganache topping in no time. Ready? Let’s get started!
1. Prepare Your Baking Pan
- Preheat your oven to 350°F (175°C).
- Line an 8×8-inch baking pan with parchment paper or lightly grease it for easy brownie removal.
- Set the pan aside for later.
2. Make the Brownie Batter
- In a large mixing bowl, whisk together the melted butter and granulated sugar until smooth.
- Add the eggs, one at a time, and stir in the vanilla extract. Whisk until everything is well combined.
- Sift in the unsweetened cocoa powder, flour, salt, and baking powder, then stir to combine.
- Pour in the whole milk and fold in the semi-sweet chocolate chips. The batter should be thick and smooth.
3. Bake the Brownies
- Pour the brownie batter into your prepared pan and spread it out evenly.
- Bake in the preheated oven for about 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (don’t overbake—this keeps them fudgy!).
- Allow the brownies to cool completely in the pan on a wire rack.
4. Make the Chocolate Ganache
- While the brownies are cooling, prepare the chocolate ganache. In a small saucepan, heat the heavy cream over medium heat until it begins to simmer (not boil).
- Remove from heat and add the semi-sweet chocolate chips and light corn syrup. Stir until the mixture is smooth and glossy.
- Let the ganache sit for a few minutes to thicken slightly.
5. Assemble the Cosmic Brownies
- Once the brownies are completely cooled, pour the chocolate ganache over the top and spread it evenly with a spatula.
- Sprinkle with rainbow candy-coated chocolate chips for the classic Cosmic Brownie look.
6. Let the Ganache Set
- Allow the ganache to set at room temperature for about 30 minutes to an hour, or place the brownies in the fridge to speed up the process.
Cooking Tips and Variations
Now that you’ve mastered the basics of making Cosmic Brownies, let’s dive into some cooking tips and variations that will take your brownies to the next level. Whether you want to make these treats even more indulgent, or switch things up for special occasions, these helpful pointers will help you get the perfect batch every time!
1. Achieve the Perfect Fudgy Texture
To get that signature fudgy texture, don’t overmix the batter. Stir the ingredients just until combined. Overmixing can lead to cakier brownies. Also, be mindful of the baking time—check them at the 20-minute mark. If you’re using a glass pan, keep in mind that it may take a few extra minutes to bake compared to metal pans.
2. Add Extra Layers of Flavor
Want to make your brownies stand out even more? Here are some fun ideas:
- Nutty Touch: Add chopped walnuts, pecans, or almonds to the batter for a crunchy contrast to the soft, gooey texture.
- Peanut Butter Swirl: Swirl in peanut butter or Nutella before baking for a rich, nutty twist.
- Minty Freshness: Add a few drops of peppermint extract to the batter or ganache for a refreshing minty flavor.
3. Use Different Toppings
The classic rainbow candy-coated chocolate chips are a must for the nostalgic look, but here are some other topping ideas:
- Mini marshmallows for a gooey, toasted flavor (just add them in the last 5 minutes of baking).
- Crushed Oreos or graham cracker crumbs for a unique, crunchy texture.
- Caramel drizzle for extra sweetness and a smooth finish.
4. Make Them Gluten-Free
If you’re looking for a gluten-free version, simply swap the all-purpose flour for a gluten-free flour blend (make sure it includes xanthan gum). This will maintain the brownies’ soft, fudgy texture without sacrificing flavor.
5. Try Different Chocolate Types
The semi-sweet chocolate chips in this recipe are perfect for a balanced sweetness, but feel free to experiment with different types of chocolate:
- Dark chocolate: For a richer, slightly less sweet brownie.
- Milk chocolate: For a sweeter, creamier flavor.
- White chocolate: For a unique, creamy contrast to the dark ganache.
6. Make Ahead and Freeze
These brownies stay fresh for several days, but if you want to bake ahead, they freeze wonderfully! Simply slice them, wrap them tightly in plastic wrap or wax paper, and store them in a freezer-safe container. When you’re ready to enjoy, just thaw them at room temperature or pop them in the microwave for a few seconds.
Serving Suggestions
Once your Cosmic Brownies are ready, it’s time to enjoy them! These brownies are incredibly versatile and can be served in a variety of fun and delicious ways. Whether you’re serving them at a party, enjoying them with a cup of coffee, or sharing them with family, here are some serving suggestions to take your brownies to the next level
For a fun twist, cut the brownies into squares, then arrange them in a pizza-like formation on a serving plate. Drizzle with whipped cream, top with some mini marshmallows, and sprinkle with more rainbow candy-coated chocolate chips. It’s a fun, interactive way to serve brownies for a party!
A warm brownie paired with a cup of coffee or a tall glass of milk is a classic combo. The richness of the chocolate pairs beautifully with the bitterness of the coffee or the creaminess of the milk. Perfect for a cozy afternoon snack!

Frequently Asked Questions
Baking Cosmic Brownies for the first time? Or maybe you’re just curious about some details before you start? No worries, I’ve compiled answers to some of the most frequently asked questions to ensure your brownies turn out perfectly.
How to Store Cosmic Brownies
After baking your Cosmic Brownies, store them in an airtight container at room temperature for up to 5 days. If you need to keep them longer, store them in the fridge for up to 1 week, or freeze them for up to 3 months. Ensure they are completely cooled before storing to maintain their moisture and texture.
How to Cut Cosmic Brownies Perfectly
To cut your Cosmic Brownies perfectly, make sure they are completely cooled before slicing. Use a sharp knife or a pizza cutter to ensure clean cuts. To avoid sticky brownies, dip the knife in warm water and wipe it clean between each cut. For neat squares, lightly score the brownies before cutting to guide your slices.
The Best Brownie Baking Pan
The best pan for making Cosmic Brownies is a 9×9-inch square pan or a 9×13-inch rectangular pan, depending on the thickness you prefer. An aluminum pan is often recommended for even heat distribution, while glass pans offer a sturdier option and tend to brown the edges more. Make sure to line your pan with parchment paper for easy removal.
How to Avoid Dry, Crumbly Cosmic Brownies
To keep your Cosmic Brownies from being dry or crumbly, be sure not to overmix the batter. Underbake slightly for a fudgy texture, as brownies continue to cook after being removed from the oven. Adding an extra egg or a little more butter can also help retain moisture, giving your brownies a soft and gooey texture.
Where to Find Rainbow Candy-Coated Chocolate Chips?
You can find rainbow candy-coated chocolate chips at most large grocery stores in the baking aisle, especially around holidays or in seasonal displays. They may also be available in online stores like Amazon or specialized baking supply websites. If you can’t find them, consider using M&M’s or similar candy-coated chocolates as a substitute.
