Finally a gluten-free Christmas cookie that is absolutely delicious! With a soft and chewy center, these Sicilian Almond Cookies have crispy edges and hold their shape very well! If you're looking for something more festive, top the cookies with sprinkles or a maraschino cherry before baking!
Measure the almond flour and confectioner's sugar into the bowl of a stand mixer with a paddle attachment. Beat on low for 30 seconds to blend the two ingredients together.
Add the orange and lemon zest. Beat on low to incorporate.
Add the egg whites and vanilla extract. Beat on low until fully incorporated.
Transfer the cookie dough to a large piping bag fitted with a star piping tip.
Pipe the dough into 1 1/2 inch rosettes onto a parchment-lined baking sheet leaving two inches of space between each cookie.
Bake for 14 minutes. Remove the cookies from the oven and allow them to rest for 5 minutes before transferring them to a wire cooling rack to finish cooling.
Once fully cooled, pack the cookies in a food-safe container. Cookies can be frozen for up to 3 months or refrigerated for 7-10 days. Do not store at room temperature for more than 5 days.
