Step 1: Prepare the Oven and Baking Sheet
Preheat your oven to 375°F (190°C). This is the optimal temperature for baking the fritters to ensure they are cooked through without burning on the outside. Line a baking sheet with parchment paper. This prevents the fritters from sticking to the baking sheet and makes cleanup a breeze. Alternatively, you can lightly grease the baking sheet with cooking spray or butter.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking powder, salt, cinnamon, and nutmeg. Whisking ensures that all the dry ingredients are evenly distributed, which is crucial for a consistent texture in the final product. Be sure to break up any lumps in the flour or sugar to prevent them from clumping in the batter.
Step 3: Combine the Wet Ingredients
In another bowl, whisk together the eggs, milk, vanilla extract, and melted butter until smooth. Whisking thoroughly ensures that the wet ingredients are fully combined and emulsified. This creates a smooth, homogeneous mixture that will incorporate easily into the dry ingredients. Make sure the butter is cooled slightly before adding it to the eggs to prevent them from cooking.
Step 4: Make the Batter
Gradually add the wet ingredients to the dry ingredients, stirring until just combined. It's important not to overmix the batter, as this can develop the gluten in the flour and result in tough fritters. Mix until the dry ingredients are moistened, but small lumps are still okay. Gently fold in the diced apples, being careful not to overmix. Overmixing can crush the apples and release too much moisture into the batter.
Step 5: Shape and Bake
Scoop heaping spoonfuls of batter onto the prepared baking sheet, spacing them about 2 inches apart. This allows the fritters to spread slightly during baking without touching each other. Use a cookie scoop or two spoons to portion the batter evenly. Bake for 14–16 minutes, or until the fritters are golden brown and a toothpick inserted into the center comes out clean. The baking time may vary depending on your oven, so keep a close eye on the fritters. Once they are golden brown and a toothpick comes out clean, they are ready. Let the fritters cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Step 6: Prepare the Glaze (Optional)
While the fritters are cooling, prepare the glaze. In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Add more milk, 1 teaspoon at a time, until you reach the desired consistency. The glaze should be thick enough to coat the fritters but thin enough to drizzle easily.
Step 7: Glaze the Fritters
Once the fritters have cooled slightly, drizzle the glaze over the top. You can also dip the tops of the fritters into the glaze. Let the glaze set for a few minutes before serving.
