Of all the cookies to give a keto makeover, a classic lemon shortbread is one of the easiest. The familiar buttery flavor, light and crumbly texture, and rich mouthfeel translate well when adapted to remove carbs from the cookie. We've swapped the sugar for a granulated sweetener and the wheat flour for almond flour, with a touch of coconut flour to improve binding. For the lemon flavor, a simple lemon extract or juice provide the customary taste that lemon cookie lovers are most familiar with. You can add 1/2 tablespoon lemon zest for an additional pop of citrus, as well. Similar to traditional shortbread cookies, the prep for these is very straight-forward, requiring no mixer or beating of butter. While the dough doesn't need to chill prior to baking, you can prepare it ahead of time, then roll out and bake when ready to enjoy.
