In a large mixing bowl, whisk together the all-purpose flour, sugar, baking powder, baking soda, and salt until well combined.

In a separate bowl, combine buttermilk, a large egg, and melted butter. Whisk until the mixture is smooth and creamy.

Gradually pour the wet mixture into the dry ingredients, stirring gently just until combined.

Gently fold in the diced peaches, ensuring they are evenly distributed throughout the batter.

Preheat a skillet or griddle over medium heat and grease the surface with cooking spray or melted butter.

Pour about 1/4 cup of batter onto the skillet for each pancake and cook until bubbles form on the surface.

Flip the pancakes and cook until golden brown and fluffy.

Stack pancakes high and drizzle with warm peach syrup, adding whipped cream and nuts if desired.
