These mint brownie cookies are inspired by the Crumbl Mint Brownie Cookie and are easily one of the most underrated flavors at Crumbl. They start with a thick, fudgy brownie-style chocolate cookie, then get topped with a fresh mint cream cheese frosting (made with mint extract, not peppermint), and finished with a silky chocolate ganache.
Unlike traditional mint chocolate chip cookies, this version tastes more like a chilled frosted brownie in cookie form.
If you love Crumbl’s chilled cookies or you’re looking for a mint chocolate dessert that isn’t overpowering, this copycat recipe delivers the perfect balance.
