To make Lime Glazed Coconut Snowballs gluten free, replace the unbleached all-purpose flour with a high-quality 1:1 gluten-free baking flour blend that contains xanthan gum. Confirm that the confectioners’ sugar, vanilla extract, cream cheese, butter, shredded coconut, and any packaged ingredients are certified gluten free or processed without gluten cross-contamination. Gluten-free dough may be slightly more delicate, so handle gently when rolling and allow the cookies to cool completely before glazing.
