Common Questions About Cosmic Brownie Cookies
Do these taste like the Little Debbie Cosmic Brownies?
Absolutely! They’re inspired by those, but in an amazing cookie form that many would argue is even better!
Can I use light corn syrup instead of the one listed?
While the original recipe calls for regular corn syrup, you can use light corn syrup as a substitute. The difference in taste is minimal.
What if I don’t have parchment paper?
You can also use a silicone mat or lightly grease the cookie sheet. The main aim is to prevent sticking.
Storage
These cookies are definitely an indulgence. As you can imagine, fudgy brownie cookies aren’t going to be part of a weight loss plan any time soon. Ha! Oh, how they call to me, though!
Refrigerator
Store in an airtight container for up to a week.
Freezer
Place the cookies in a single layer inside a freezer-safe container. They can be frozen for up to 2 months. Thaw at room temperature before indulging.
Tips
Any time my kids know I’m going to bake cookies, they’re excited. Something about this recipe, though, causes more of a stir than usual. Maybe it’s the brownie-like texture, maybe it’s the sight of them. Either way, kids go nuts over these things!
- Don’t overbake! They might look a bit soft, but they will set as they cool to give that chewy brownie texture.
- For a creamier texture, use heavy whipping cream in place of heavy cream for the ganache.
- If you’re after the exact Cosmic Brownies recipe look, aim for those rainbow-coated chocolate chips or rainbow sprinkles.
- For perfect cookies, always leave some space between the cookie dough balls on the cookie sheet.

Nothing too complicated for these chewy brownie cookies. If you don’t have rainbow chips, try using mini M&M’s! You’ll still get the chocolate rainbow effect.

- Brown sugar
- Granulated sugar
- Egg
- Corn syrup
- Vanilla extract
- All-purpose flour

How to Make Cosmic Brownie Cookies
You’re going to love these. I’m super excited that you get to try them! I know I’m a little biased, but I think they’re better than the original. Definitely let me know what you think once you’ve made them yourself!
- Preheat the oven to 350 degrees Fahrenheit. Prepare a 9×11 baking sheet with parchment paper and set aside.
- In a mixing bowl, cream the butter, brown sugar, and granulated sugar together until creamy and fluffy.
- Add the wet ingredients- egg, corn syrup, and vanilla extract, blending again with a hand mixer until combined.
- Continue by adding the dry ingredients: flour, cocoa powder, baking soda, and salt. Mix on medium speed until all the wet and dry ingredients are incorporated.
- Use a cookie scooper, to take a large ¼ cup size of dough into your hands and roll it into a ball. Place the dough ball on the baking sheet and flatten with your hand to about ½ inch thick.
- Repeat this process with the rest of the cookie dough.
- Bake the cookies for 11 minutes. Do not overbake. If they look a little undercooked, they will set as they cool.
- While the cookies bake, make the ganache. Heat the heavy cream in a small saucepan until warm and steaming, but not boiling.
- Pour the hot cream over the chocolate chips and let sit for 3 minutes before touching. After 3 minutes have passed mix until shiny and smooth.
- Place a tablespoonful of ganache in the center of each brownie cookie and use a circular motion with the spoon to spread it towards the edge. Top with rainbow chocolate sprinkles.
- Place the decorated cookies in the fridge in a single layer and let the ganache harden for 10 minutes or at room temperature for an hour.
