In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 tablespoon of baking powder, 1 teaspoon of ground cinnamon, ¼ teaspoon of ground nutmeg, and ½ cup of granulated sugar.

In a separate bowl, whisk 2 large eggs, 1 cup of milk, ½ cup of melted butter, and 1 teaspoon of vanilla extract until smooth.

Gradually pour the wet ingredients into the dry mixture, stirring gently with a spatula until just combined. Fold in 1 cup of chopped apples.

Preheat your waffle iron to medium-high heat and lightly grease the plates.

Spoon batter into the center, approximately ⅓ cup per donut shape. Close the lid and cook for about 3-4 minutes.

While the waffle donuts are cooking, prepare the glaze by whisking together 1 cup of powdered sugar and 2-3 tablespoons of milk until thick but pourable.

Remove the waffle donuts from the waffle iron, drizzle the warm glaze over the donuts, and serve warm.
