Preheat your oven to 375°F (190°C).
In a large bowl, whisk together flour, baking powder, cinnamon, nutmeg, salt, and sugar.
In another bowl, combine milk, eggs, and vanilla extract.
Pour the wet ingredients into the dry ingredients, mixing until just combined.
Gently fold in the diced apples.
Line a baking sheet with parchment paper.
Using a spoon, drop batter onto the baking sheet, spacing them about 2 inches apart.
Bake for 20-25 minutes, or until golden brown.
Remove from the oven and let cool for a few minutes.
Dust with powdered sugar before serving.
