Nothing beats citrus desserts in the middle of winter. Unless, of course, it’s these fudgy flourless brownies! But if I can’t have those brownies, I’ll take a citrus dessert! I’ve been wanting to incorporate grapefruit into more desserts, but they usually get forgotten when I start baking. These snickerdoodle cookie bars with grapefruit buttercream frosting changed that!
The cookie bars start out with a traditional snickerdoodle cookie that is extra thick and chewy. You could make these in to individual cookies, but really, why spend the time making individual cookies when all you have to do is press all of the dough into one pan and be done with it?! The surprise comes in the creamy buttercream frosting that is bursting with sweet and tangy grapefruit.
When you juice your grapefruit, don’t strain out the pulp. It adds flavor and a burst of pink. The grapefruit zest is optional but adds more flavor and flecks of color. Between the fresh grapefruit juice and zest, the buttercream frosting is light on color but heavy on flavor! My husband took a bite of these bars and thought that they tasted like summer. So, if you’re looking for an escape from a long winter, or if you just like a good citrus dessert, these snickerdoodle cookie bars with grapefruit buttercream are just what you need!
