Creating your Air Fryer Funfetti Cake is straightforward if you follow these easy steps:

1. Prepare the Air Fryer: Preheat your air fryer to 320°F (160°C).
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream Butter and Sugar: In a separate bowl, beat the softened butter and granulated sugar together until fluffy.
4. Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Then stir in the vanilla extract.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, alternating with the milk until everything is well combined.
6. Add Sprinkles: Gently fold in the rainbow sprinkles, reserving a few for the cake top.
7. Prepare the Baking Dish: Grease an air fryer-safe baking pan and pour in the batter, smoothing the top for an even bake.
8. Air Fry the Cake: Place the pan in the air fryer and cook for 25-30 minutes or until a toothpick comes out clean when inserted into the center.
9. Cool the Cake: Once cooked, carefully remove the cake from the air fryer and let it cool in the pan for 15 minutes before transferring it to a wire rack to cool completely.
10. Decorate: Once cool, top with frosting or whipped cream and sprinkle additional rainbow sprinkles on top for a joyful presentation.
