Preheat your oven to 350°F (175°C).

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition, and stir in the vanilla extract.

In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.

Gradually mix the dry ingredients into the wet mixture until just combined.

Gently fold in the diced peaches.

Drop tablespoon-sized amounts of dough onto a lined baking sheet.

Bake in the preheated oven for 12-15 minutes or until the edges are lightly golden.

Let the cookies cool on the baking sheet for a few minutes before transferring them to a cooling rack.
