Day 15 of #25DaysOfCookies! Have you tried Christmas Spice Cookies (known as Lebkuchen)? These #German Christmas #cookies are essentially spice-nut cookies—chock-full of ground nuts and flavored with a healthy dose of lemon and orange zest. Bake up your own batch this week (link clickable in our bio) and be sure to tag your photos with #ATKHoliday along the way.
