1. Prepare the batter: In a large mixing bowl, combine 1 cup of flour, 1 tablespoon of sugar, 1 teaspoon of baking powder, and 1/4 teaspoon of salt. Mix the dry ingredients well.

2. Mix wet ingredients: In another bowl, whisk together 3/4 cup milk, 1 egg, and 1/2 teaspoon vanilla extract. Slowly add the wet mixture to the dry ingredients, whisking until you get a smooth, lump-free batter. The batter preparation is key to a good funnel cake.

3. Transfer the batter: Pour the batter into a funnel or squeeze bottle for easy dispensing.

4. Preheat the air fryer: Set your air fryer to 370 degrees Fahrenheit and let it preheat for about 3 minutes.

5. Air fry the funnel cakes: Lightly spray the air fryer basket with cooking spray. Drizzle the batter in a circular pattern to form the funnel cake. Be careful not to overcrowd the basket.

6. Cooking funnel cake in air fryer: Air fry at 370 degrees Fahrenheit for 5-6 minutes, flipping halfway through to ensure even cooking. The funnel cake should be golden brown and crispy.

7. Serve: Remove the funnel cake with tongs and place it on a plate. Sprinkle with powdered sugar or add your optional toppings.
