Perfect for small batches
-
Ideal for hot climates (no need to heat the whole kitchen)

If you’ve already mastered air fryer pancakes or breads, this cake is your next step.
Ingredients
-
3 large eggs (room temperature)
-
¾ cup granulated sugar
-
1 teaspoon vanilla extract
-
1 cup all-purpose flour (sifted)
-
1 teaspoon baking powder
-
2 tablespoons milk (room temperature)
-
2 tablespoons melted butter or neutral oil
-
Pinch of salt
Ingredient Tips for Maximum Fluffiness
Room Temperature Eggs:
This is crucial. Eggs whip better at room temperature, creating more volume and a lighter cake.
Sifted Flour:
Sifting removes lumps and incorporates air, keeping the batter light.
Gentle Folding:
Overmixing deflates the air bubbles. Fold slowly and carefully.
Equipment Needed
-
6-inch round cake pan (must fit inside your air fryer basket)
-
Parchment paper
-
Electric hand mixer or stand mixer
-
Mixing bowls
-
Spatula
Step-by-Step Instructions
Step 1: Prepare the Pan
Line the bottom of a 6-inch round cake pan with parchment paper. Lightly grease the sides.
Preheat your air fryer to 160°C (320°F) for 3–5 minutes.
Step 2: Whip Eggs and Sugar
In a large bowl, combine the eggs, sugar, and salt. Beat with an electric mixer on high speed for 5–7 minutes.
The mixture should become pale, thick, and tripled in volume. When you lift the beaters, the batter should form ribbons that slowly disappear back into the mixture.
This step is the secret to a fluffy sponge.
Step 3: Add Vanilla
Mix in the vanilla extract gently.
Step 4: Fold in Dry Ingredients
Sift together the flour and baking powder.
Add the flour mixture in three batches, gently folding with a spatula using slow, upward motions. Do not stir aggressively.
Step 5: Add Milk and Butter
Mix the milk and melted butter together.
Take 2 tablespoons of the batter and mix it into the milk mixture first. Then gently fold this back into the main batter. This prevents deflation.
Step 6: Bake in the Air Fryer
Pour the batter into the prepared pan and gently tap it on the counter to release air bubbles.
Place the pan into the air fryer basket.
Bake at 160°C (320°F) for 20–25 minutes.
Check doneness by inserting a toothpick into the center. If it comes out clean, the cake is ready.
If the top browns too quickly, loosely cover it with foil halfway through baking.
Step 7: Cool Properly
Remove the cake and let it cool in the pan for 10 minutes.
Run a knife around the edges and transfer to a wire rack to cool completely before slicing.

Common Mistakes to Avoid
1. Not Whipping Eggs Enough
Under-whipped eggs lead to dense cake.
2. Overmixing Flour
This removes trapped air and reduces fluffiness.
3. High Temperature
Air fryers cook quickly. Too high heat can brown the outside while leaving the inside undercooked.
4. Opening the Basket Too Early
Avoid checking before 15 minutes. Sudden temperature drops may cause sinking.
