Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.

In a mixing bowl, whisk together flour, salt, and baking soda until combined.

In a large bowl, beat together the softened butter, granulated sugar, and light brown sugar until light and fluffy. Then add in the egg and vanilla extract.

Gradually stir the dry ingredient mixture into the wet ingredients, then fold in the chopped peaches and peach preserves.

Drop spoonfuls of dough onto the prepared baking sheets, keeping 2 inches apart.

Mix sanding sugar and ground cinnamon in a small bowl and sprinkle over dough.

Bake for 11 to 13 minutes until golden around the edges.

Allow cookies to cool on baking sheets for 5 minutes before transferring to a wire rack.
