Preheat the Oven: Preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper. This helps prevent the cookies from sticking and ensures even baking.

Cream the Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture becomes light and fluffy. This step is crucial as it creates the base texture for your cookies.

Add Eggs and Vanilla: Beat in the eggs one at a time. Make sure each egg is well incorporated before adding the next. Then, add the vanilla extract, which brings a lovely aroma and depth of flavor to the cookies.

Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. This blend of dry ingredients gives the cookies their structure and a hint of spice.

Combine Wet and Dry Ingredients: Gradually add the dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can make the cookies tough.

Fold in Peaches: Gently fold in the diced peaches and white chocolate chips (if using). The peaches add a juicy burst of flavor, while the white chocolate chips add a hint of sweetness.

Scoop and Sprinkle: Using a cookie scoop or spoon, drop dough onto the prepared baking sheets, spacing them about 2 inches apart. Sprinkle a little granulated sugar on top of each cookie for an extra touch of sweetness.

Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly soft, but they will set as the cookies cool.

Prepare the Glaze: While the cookies are baking, prepare the glaze by whisking together powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more milk if needed.

Glaze the Cookies: Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. Once completely cooled, drizzle the glaze over the cookies. Enjoy your peach cobbler cookies with a glass of milk or a cup of tea!
