Super soft and chewy brownie cookies with deep, rich chocolate flavor are topped with semi-sweet chocolate ganache and colorful rainbow sprinkles to create a treat that’s equal parts cookie and brownie and 100% delicious!
Growing up, I remember being so excited when my mom would grab a box of Cosmic Brownies at the grocery store. That super moist brownie topped with chocolate frosting and colorful sprinkles was just about my favorite snack. Even today, I still love them! I also love to experiment with my favorite flavors, which is why I made these Cosmic Brownie cookies. They combine the best of both worlds into one dessert full of deep, rich chocolate flavor and a metric ton of nostalgia.

Hint
Bring your cream to a simmer but don’t let it boil. Otherwise, it will curdle.
Storage

What to Serve with Cosmic Brownie Cookies
This recipe is part cookie and part brownie, so it should come as no surprise that it’s delicious with a glass of milk or a cup of coffee or tea. Fresh fruit and nuts are also a wonderful pairing with these brownie cookies.
Tips
- Don’t overmix your dough. Everything should be just combined, meaning all the dry ingredients are moistened. This helps keep the cookies soft and chewy.
- Mixing the dough by hand is the easiest way to ensure it’s fully combined without being overmixed.
- Let your cookies fully cool before adding the ganache. Otherwise it won’t stay in place.
Frequently Asked Questions
Cosmic Brownie cookies are a mashup of brownies and cookies topped with chocolate ganache and colorful sprinkles to mimic the flavor and texture of Cosmic Brownies.
Dry brownies are usually the result of using too much flour. Loosely spoon your flour into the measuring cup rather than scooping the cup directly into the flour. This prevents packing and using too much.
Brownie cookies are done when the tops begin to crack. Because they’re cookies, they’re a little too thin for the toothpick test.
Ganache can separate if the ingredients aren’t at similar temperatures. It’s important to let your hot cream and chocolate chips sit for a few minutes to allow the chocolate chips to warm up before mixing. This helps the chocolate melt and mix more evenly with the heavy cream.
