Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Line a large baking sheet with parchment paper or a silicone baking mat and set aside.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, granulated sugar, baking powder, salt, cinnamon, and nutmeg until evenly combined.

Step 3: Combine the Wet Ingredients

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

Step 4: Prepare the Apples

Peel, core, and dice the apples into small, bite-sized pieces. Gently fold the diced apples into the wet ingredients to ensure even distribution.

Step 5: Combine the Dough

Gradually add the wet ingredients to the dry ingredients, mixing with a spatula or wooden spoon until just combined. Do not overmix; the dough should be thick and slightly sticky.

Step 6: Add Optional Cinnamon-Sugar Filling

If using the cinnamon-sugar filling, sprinkle the brown sugar and cinnamon mixture over the dough. Lightly fold it in, creating swirls rather than fully incorporating it.

Step 7: Shape the Fritters

Using a large spoon or ice cream scoop, drop mounds of dough onto the prepared baking sheet, spacing them about 2 inches apart. Aim for a rough, slightly irregular shape to mimic the look of traditional fritters.

Step 8: Bake

Bake in the preheated oven for 15-18 minutes, or until the fritters are golden brown and a toothpick inserted into the center comes out clean.

Step 9: Make the Glaze

While the fritters bake, prepare the glaze by whisking together the powdered sugar, milk, and vanilla extract in a small bowl until smooth. Adjust the consistency by adding more milk, 1 teaspoon at a time, if needed.

Step 10: Glaze the Fritters

Remove the fritters from the oven and let them cool slightly on the baking sheet for 5 minutes. Drizzle the glaze over the warm fritters using a spoon or pastry brush. For a thicker glaze, allow the fritters to cool completely before glazing.

Step 11: Serve

Serve the baked apple fritters warm or at room temperature. Enjoy them plain or with your favorite hot beverage.
