Preheat your oven to 350°F (175°C).

In a mixing bowl, beat together 1 cup of softened unsalted butter and 1 cup of granulated sugar for about 2-3 minutes until light and fluffy.

Incorporate 2 large eggs, one at a time, mixing on low speed. Add 1 teaspoon of vanilla extract and mix until blended.

In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and 1 teaspoon of cinnamon. Slowly add to the wet mixture.

Gently fold in 1 to 1.5 cups of diced fresh peaches.

Using a cookie scoop or tablespoon, drop rounded spoonfuls onto prepared baking sheets, spaced about 2 inches apart.

Sprinkle about 1 teaspoon of brown sugar on top of each dough ball.

Bake for 12-15 minutes or until golden edges and soft centers.

Let cookies cool on the baking sheet for about 5 minutes before transferring to a wire rack.
