Preparation Steps

• Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
• In a large bowl, whisk together the flour, sugar, baking soda, baking powder, salt, and cinnamon.
• In another bowl, mix the melted butter, egg, milk, and vanilla extract until well combined.
• Add the wet ingredients to the dry ingredients and mix until just combined. Fold in the diced peaches.
• Divide the batter evenly among the muffin cups.
• Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.
• Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
