Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

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

Add the egg, vanilla extract, and apple cider to the mixture and combine well.

In a separate bowl, whisk together flour, baking soda, cinnamon, nutmeg, and salt. Gradually mix into the wet ingredients until combined.

Fold in diced apples until evenly distributed.

Scoop dough into balls and place on the baking sheet, a few inches apart.

Bake for 10-12 minutes until edges are golden but centers are still soft.

Cool on the baking sheet for a few minutes, then transfer to a wire rack. Whisk powdered sugar with apple cider for glaze and drizzle over cookies.
