To make this recipe gluten-free, replace the all-purpose flour with a gluten-free 1:1 baking flour blend suitable for muffins.
Confirm that the baking soda, shredded coconut, nuts, raisins, vanilla extract, and orange juice are labeled gluten-free.
Use certified gluten-free oats or seeds only if adding them as substitutions.
Gluten-free muffin batter may be slightly thicker or more delicate, so stir gently and avoid overmixing.
Use clean mixing bowls, utensils, muffin tins, and cooling racks to prevent cross-contamination.
