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

In a large mixing bowl, whisk together all-purpose flour, granulated sugar, baking powder, salt, ground cinnamon, and nutmeg until combined. Set aside.

In a separate bowl, whisk together milk, eggs, vanilla extract, and melted unsalted butter until smooth.

Pour the wet mixture into the dry ingredients, stirring gently until just combined. The batter should be thick yet pourable.

Fold in the diced apples, ensuring they are evenly distributed throughout the batter.

Using a spoon or cookie scoop, drop mounds of batter onto the prepared baking sheet, leaving 2 inches of space between each fritter.

Bake for 15–18 minutes or until golden brown and a toothpick comes out clean.

Prepare the glaze by mixing powdered sugar with a splash of milk in a small bowl until smooth.

Drizzle the glaze over the slightly cooled fritters and serve warm.
