To make this recipe gluten-free, substitute the all-purpose flour with a gluten-free flour blend that is suitable for baking (such as a 1-to-1 gluten-free baking flour). Ensure the baking powder used is certified gluten-free, as some brands may contain gluten-based additives. Verify all other ingredients, such as baking powder and vanilla extract, are labeled gluten-free to avoid cross-contamination. The recipe’s proportions may remain the same, though you may need to allow the batter to rest for 5–10 minutes to hydrate the gluten-free flour and improve texture.
