Cosmic Brownie Cookies
Deeply chocolatey with thick, tender bases, indulgent fudgy frosting, and the classic, colorful smattering of cosmic sprinkles (of course), cosmic cookies are an obvious adaptation of iconic cosmic brownies. To be honest, I couldn’t tell you which of the two homemade versions I prefer. The base for this recipe was an easy one to choose. I opted for the same chewy, brownie-style cookie that I’ve used on several of my gourmet cookies (including my buckeye cookies and dirt cookies). It’s a nice, thick cookie base that works well with scores of different toppings, but it neatly fit the bill for the nostalgic chocolate experience I was aiming to recreate.
Why This Recipe Works:
Taste: Chocolately and rich, but not too decadent. And there’s no chemical taste, unlike the real thing. Looks: Nostalgic and fun–just like the cosmic brownies from your childhood! Ease: No mixer required, since we are starting with melted butter instead of softened. Time: Only 30 minutes of chilling! This will help the dough be thick and sturdy enough to hold the frosting.
I’ve been having a lot of fun with nostalgic treats (like my Lucky Charms Treats) and gourmet cookies lately, and this recipe combines the two. I hope you love them as much as we do!
What You Need
Before we get started there are a few ingredient choices I’d like to go over (like the various types of chocolate we use). SAM’S TIP: Stick with light brown sugar for this recipe, since dark brown would make these cosmic cookies a bit too rich. If you don’t have either on hand, then hop on over to my post on how to make brown sugar and learn how to make your own! Remember, this is just an overview of the ingredients I used and why.

Ganache & Assembly
SAM’S TIP: It’s very important that you heat the chocolate fudge frosting slowly in the microwave. If it is heated too fast, then the ganache can break and become greasy. I provide specific instructions for this below. I had a lot of fun with these, so if you have an idea for another nostalgic dessert-turned-cookie let me know below in the comments! Enjoy!
