To make these Pumpkin-Spice Pancakes with Warm Maple Syrup gluten-free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Confirm that the baking powder, baking soda, pumpkin spice, cinnamon, vanilla extract, brown sugar, maple syrup, and optional toppings are certified gluten-free. Use a clean skillet, utensils, and mixing bowls to prevent cross-contamination.
