Preheat your air fryer to 350°F (175°C) for about 5 minutes.

In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.

In a separate bowl, beat the eggs, then mix in the milk, vanilla extract, and melted butter until smooth.

Gradually combine the dry mixture with the wet ingredients, stirring until you achieve a smooth batter with no lumps.

Lightly spray the air fryer basket with non-stick cooking spray to prevent sticking.

Using a spoon, drop small dollops of batter onto the greased air fryer basket, spacing them apart to allow for expansion.

Cook in batches for about 3-4 minutes, flipping halfway through.

Remove the funnel cake bites and place them on a cooling rack or plate to cool slightly.

Dust your warm funnel cake bites with powdered sugar just before serving.
