These Thanksgiving Sugar Cookies with Royal Icing Leaves are the perfect holiday treat—firm enough to hold a sharp leaf shape, tender enough to melt on your tongue, and decorated with glossy royal icing in autumn colors. A nostalgic recipe that’s ideal for make-ahead baking and sharing with loved ones.
Chill the dough for at least 30 minutes to prevent spreading. For best results, bake cookies one day and decorate the next. The 10-second rule for royal icing consistency: lift your spoon and count to 10—if the icing ribbon disappears back into the bowl within 10 seconds, it’s perfect. Do not ice warm cookies. Store decorated cookies in an airtight container at room temperature for up to 2 weeks. Freeze undecorated cookies for up to 3 months.
