Air Fryer Pumpkin Fritters with Cinnamon Sugar

In a medium mixing bowl, whisk together pumpkin puree, egg, sugar, and vanilla until smooth.
Gradually add flour, baking powder, cinnamon, nutmeg, and salt until a thick batter forms. If the batter feels too stiff, add milk a tablespoon at a time until scoopable.
Lightly grease your hands. Scoop spoonfuls of batter and roll into balls. Place them in a greased air fryer basket, leaving space between each. Brush the tops lightly with melted butter.
Air fry at 350℉ for 8-10 minutes, turning once halfway, until golden brown and cooked through.
To make the coating, stir together ½ cup granulated sugar and 1 teaspoon ground cinnamon in a shallow bowl.
While still warm, roll the fritters in the cinnamon sugar mixture until coated evenly. Serve immediately for the best texture.
