To make these Lime Glazed Coconut Snowballs gluten-free, substitute the unbleached all-purpose flour with a high-quality 1:1 gluten-free baking flour blend that includes xanthan gum. Ensure that the sweetened shredded coconut and other ingredients are certified gluten-free, as cross-contamination can occur with packaged goods. Baking time remains the same, though texture may be slightly more delicate.
