They’re basically little cakes that taste like fresh donuts from a bakery. Soft and fluffy on the inside, coated in buttery cinnamon sugar on the outside.

You don’t need any fancy equipment or hard-to-find ingredients. Just some flour, sugar, milk, butter, an egg, and a few spices. Simple stuff you probably already have at home.
The air fryer does all the heavy lifting here. In about 10 minutes you get golden little cakes that are ready to be coated and eaten.
This is one of those recipes that works great for breakfast, snack time, or whenever you just want a little something sweet. It’s easy, quick, and always a hit.

Ingredients
For the Cakes
- 3/4 cup All-Purpose Flour
- 1/3 cup Granulated Sugar
- 1 tsp Baking Powder
- 1/4 tsp Salt
- 1/4 tsp Ground Nutmeg
- 1/3 cup Whole Milk
- 1 Large Egg
- 2 tbsp Melted Butter
- 1/2 tsp Vanilla Extract
For the Coating
- 3 tbsp Melted Butter
- 1/3 cup Granulated Sugar
- 1 tbsp Ground Cinnamon
How to Make
Step 1
In a bowl, combine flour, sugar, baking powder, salt, and nutmeg. In another bowl, whisk together milk, egg, melted butter, and vanilla.

Step 2
Pour wet ingredients into dry ingredients and stir until just combined and smooth.
Step 3
Grease four 4-oz ramekins or small donut-shaped silicone molds. Fill each about two-thirds full with batter.

Step 4
Preheat air fryer to 340°F. Place filled ramekins in the basket and cook for 10-12 minutes until golden and a toothpick comes out clean.
Step 5
Let cakes cool for 3 minutes, then remove from ramekins. While still warm, brush each cake all over with melted butter.
Step 6
Mix cinnamon and sugar in a shallow bowl. Roll each buttered cake in the cinnamon sugar mixture until completely coated. Serve warm.

Tips
Don’t Overmix the Batter
When you pour the wet ingredients into the dry, stir gently just until everything comes together and you don’t see any pockets of flour. The batter should look smooth but you don’t need to beat it aggressively.
Overmixing develops the gluten in the flour, which makes the cakes dense and chewy instead of soft and cake-like. Think of it like this – once the dry stuff looks wet, stop stirring.
A spatula or wooden spoon works better here than a whisk. You want to fold the batter together, not whip air into it.
Fill the Ramekins the Right Amount
The recipe says two-thirds full and that’s important to follow. The batter rises as it bakes, and if you fill the ramekins too high, the batter will puff up over the edge and spill into your air fryer basket.

If you fill them too little, you’ll end up with flat, thin cakes that dry out fast. Eyeball the two-thirds mark on each ramekin and try to divide the batter evenly between all four so they cook at the same rate.
Grease the Ramekins Well
Don’t skip greasing the ramekins or go light on it. Use a little bit of butter or nonstick cooking spray and make sure you cover the bottom and all the way up the sides. These cakes are small and delicate, so if they stick even a little, they’ll break apart when you try to pop them out.
If you’re using silicone molds, you still want to give them a light spray. Silicone is easier to work with, but the batter can still cling to it without a bit of grease.

Frequently Asked Questions
Can I use self-rising flour instead of all-purpose flour?
You can, but you’ll need to leave out the baking powder and salt since self-rising flour already has both of those mixed in. Everything else in the recipe stays the same.
The texture might be very slightly different, but it will still taste great and rise just fine in the air fryer.
