Follow these simple steps to create your Fluffy Gluten-Free Peach Muffins:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.

1. Mix Dry Ingredients: In a large mixing bowl, combine the gluten-free flour, sugar, baking soda, baking powder, salt, and ground cinnamon. Whisk together until fully combined.

1. Prepare Wet Ingredients: In another bowl, whisk together the beaten egg, buttermilk, vegetable oil, and vanilla extract until well blended.

1. Combine Mixtures: Pour the wet ingredients into the dry ingredients. Stir gently until just combined, being careful not to over-mix.

1. Add Peaches: Gently fold in the chopped fresh peaches into the muffin batter.

1. Fill Muffin Tin: Spoon the batter evenly into the prepared muffin cups, filling each about ¾ full.

1. Bake: Place the muffin tin in the preheated oven and bake for about 20-25 minutes or until a toothpick inserted into the center comes out clean.

1. Cool Your Muffins: Once baked, remove the muffins from the oven. Allow them to cool in the tin for 5-10 minutes before transferring them to a wire rack to cool completely.

1. Enjoy: These Fluffy Gluten-Free Peach Muffins are best enjoyed fresh but can be stored in an airtight container for a couple of days.
