What Cookie Flavor is Cosmic Brownie Crumbl Cookies?

The ingredient used to flavor the cookie in this recipe cocoa powder. This will give the cookie a very chocolatey and delicious flavor.

Important Ingredients You Will Need to Make Cosmic Brownie Cookie

  • Light Corn Syrup-This adds a bit of texture to the cookies. Corn syrup works differently and doesn’t provide sugar crystals in the cookies.
  • Cocoa Powder- I recommend using a high quality cocoa powder for a rich deep flavor.
  • Heavy Cream and Semi-Sweet Chocolate Chips- This make the creamy ganache over the top that take these cookies over the top.
  • Rainbow Coated Chocolate Chips- If you can not find rainbow coated chocolate chips, you can use regular semi sweet chocolate chips or mini M&Ms.
