Not only are these cookies beautiful, but they are easy too; Cosmic Brownie Cookies are a hit with the whole family. Using boxed brownie mix, they come together in no time!
I love making twists on classic recipes, but I absolutely also adore copycat recipes, so we are smashing those two together with these Easy Cosmic Brownie Cookies. Iconic on their own, cosmic brownies get made into cookie form, could there BE a more delicious pairing? I think not!
These cookies automatically transfer me to my childhood. I’ve always loved Little Debbie snacks, and now with this recipe, I get to make a twist on one of their classics whenever I want.
Lily is also obsessed with all things sugar, I mean, she’s 3… can you blame her?!
She was so excited when I recently whipped up another batch of these cookies. She is at that age when she can finally help Mama in the kitchen, and we had a blast making them.
Rich and chocolatey brownie cookies (made from box mix!!) with a silky chocolate ganache on top, can it get any better? It does when you add those iconic rainbow candy chip sprinkles, pure chocolate bliss.
Cosmic Brownie Cookies must be featured on your next dessert table. With all the oohh’s and ahhh’s, you will be getting asked for the recipe again and again.

WHY THIS RECIPE WORKS:
- Only 6 pantry ingredients are needed!
- A fun twist on the classic cosmic brownies makes this fun for the whole family.
- Ready in about an hour, start to finish.
INGREDIENTS NEEDED (FULL RECIPE BELOW):
- Box brownie mix
- Vegetable oil
- Large egg
- Semi-sweet baking bar
- Heavy cream
- Rainbow candy chip sprinkles
HOW TO MAKE COSMIC BROWNIE COOKIES:
- Line a sheet pan with parchment paper and set it aside.
- Mix together the brown mix, oil, and egg until combined in a large bowl. The mixture will be thick.
- Taking about 2 tablespoons of the brownie cookie dough and roll it into a ball with your hands. Place the cookie dough ball on the sheet pan, and repeat with the remaining dough.
- Place the sheet tray with the cookie dough balls into the refrigerator for 30 minutes to chill.
- Preheat the oven to 350°F. Line sheet pans with parchment paper.
- Place the cookie dough balls about 2-3 inches apart on the sheet pans. Bake for 9-11 minutes or until the tops of the cookies do no longer appear glossy. Be careful not to overbake.
- Let the cookies cool for 10 minutes on the sheet pans and then transfer them to a wire rack to completely cool.
- Make the chocolate ganache when the cookies have completely cooled. Finely chop the baking bar. Place it into a heatproof bowl.
- Pour the heavy cream into a small saucepot and bring it just to a simmer, as soon as you see the first bubbles, it’s ready. Pour the hot cream over the chopped chocolate. Let it sit for 5 minutes and then whisk it until smooth.
- One by one, take the cookies and dip the tops into the ganache. Place it back on the wire rack ganache side up and immediately top it with the rainbow candy chip sprinkles. Repeat with the remaining cookies.
CAN I ADD ANYTHING TO THE COOKIES?
Absolutely. The recipe provided here is more of a copycat of the original cosmic brownies recipe but in cookie form, but you sure can add to them!
Fun additions to the brownie batter:
- Chocolate Chips (white, semi-sweet, milk, or dark)
- Sprinkles
- Chopped Nuts
Other fun toppings:
- Rainbow jimmie sprinkles
- Mini chocolate chips
- Chopped Nuts
- Crushed Cookies (Oreos, Crunchy Chocolate Chip Cookies, Shortbread Cookies)
- Drizzle of melted chocolate (white, semi-sweet, milk, or dark)
If you are adding additional toppings, I suggest adding them in step 10, when you would be adding the candy crunch sprinkles.
You can also mix up the ganache from semi-sweet to milk, dark, or white chocolate to suit your taste.
DO I HAVE TO USE A BOX MIX?
No, if you already have a favorite brownie cookie recipe, you can make that and add the ganache and candy crunch sprinkle topping.
My favorite brownie box mix is Betty Crocker’s fudge brownie mix, but you can use your favorite.
WHERE TO FIND RAINBOW CANDY CHIP SPRINKLES?
I like to get mine at the local grocer, but sometimes they don’t have them. In a pinch, I’ll get them on Amazon here.
CAN I USE A DIFFERENT FROSTING?
Yes, if you don’t want to use or make the ganache, you can frost these cookies with something else.
I would keep to the chocolate theme and use a classic chocolate buttercream frosting. My chocolate malt buttercream frosting would be fantastic!
Just use a butter knife and smear a little frosting on top of each cookie, then add the sprinkles.
HOW TO STORE:
Store any leftover cookies in an airtight container for up to 5 days at room temperature.
Freeze cookies by putting them in an airtight freezer-safe container with pieces of wax paper in between. Freeze for up to 3 months.
To defrost, place frozen cookies in the fridge overnight or on the countertop.
TIPS AND TRICKS:
- This makes 15 cookies, but you can easily double it to make more.
- Lots of custom options, see my tips above on that.
- Homemade brownie cookies can be used in place of the box mix.
- Can be frozen, see above for how to store.
- Find the specific rainbow chip sprinkles on Amazon or your local grocer.
