These easy gluten-free Christmas sugar cookies with royal icing are crisp, buttery, and sturdy enough to hold a thick layer of royal icing without crumbling. They’re not a sad substitute for the ‘real’ thing—they’re their own beautiful thing, perfect for holiday cookie exchanges and decorating with family.
Chill the dough for at least 30 minutes to prevent spreading. For sharper edges, chill cut-out shapes on the baking sheet for 10 minutes before baking. Don’t overwork the dough—mix just until combined. Watch baking time closely; gluten-free cookies can overbake quickly. For royal icing, outlining consistency should hold a stiff peak; flooding consistency should flow like honey. Store undecorated cookies in an airtight container for up to 2 weeks, decorated cookies for up to 10 days. Freeze unbaked dough for up to 3 months.
