To make this recipe gluten-free. Simply swap out the all-purpose flour. With a 1:1 gluten-free baking flour. Ensure that the baking powder. And baking soda. Are also gluten-free. As some brands. May contain traces of gluten. You can use gluten-free oats. If you’d like to add a bit of texture. The Greek yogurt. And other ingredients. Are naturally gluten-free. So no need to worry there. The result is just as delicious. With the same moist, tender crumb. And all the cozy apples. And cinnamon flavors you love.
