Chocolate Cake in the Air Fryer

An air fryer chocolate cake is a small, rich sponge that bakes in about 28 minutes in a 15 cm tin, with no need to heat a full oven. It suits a household of two to six and leaves you with a soft, dark crumb and a glossy ganache. This recipe covers the tin that fits, the right temperature and the foil trick that keeps the top from burning.

Why the air fryer works for chocolate cake

An air fryer chocolate cake bakes quickly because the small chamber surrounds the tin with moving hot air. A 15 cm sponge is done in under 30 minutes, with a soft crumb and a thin, even crust. Chocolate cake in air fryer baskets also uses much less energy than a full oven, which makes it sensible for a small bake. The fan, though, browns the top fast, so you bake at 160 °C and cover it with foil halfway through.

Tin size decides whether the cake works. A 15 cm deep round tin fits most 4–6 litre baskets, while an 18 cm tin only fits wide 6 litre ones. If you only have a loaf tin, a 450 g size fits and makes a good chocolate loaf cake. The basket needs a gap of 2–3 cm around the tin so the air can move.

Tips

  • Use soft butter. Butter straight from the fridge will not cream properly and gives a heavy cake. Soften it at room temperature for an hour.
  • Sift the cocoa. Cocoa powder forms hard lumps that do not break up in a thick batter. Sifting guarantees a smooth, even crumb.
  • Cool before you ice. Ganache on a warm cake slides off and goes thin. Wait until the sponge is completely cold.

Serving

Spread the ganache over the cooled cake and serve in slices with a spoonful of cream or fresh raspberries. A small cake like this suits a tea-time table with cupcakes or brownies, and you will find more ideas in the dessert section. Plain, unfrosted slices are also good with a mug of tea.

Storing and reheating

Keep the iced cake in an airtight container for 3 days. Undecorated sponge freezes well for up to 3 months. To warm a slice, put it in the air fryer at 160 °C for 2–3 minutes until soft in the middle.

Variations

  • Chocolate orange: Add the zest of one orange to the batter and a splash of orange juice to the ganache.
  • Chocolate loaf cake: Bake the same batter in a lined 450 g loaf tin at 160 °C for 30–35 minutes and dust with icing sugar instead of ganache.
  • Chocolate chip: Fold 50 g milk chocolate chips into the batter before baking.

Troubleshooting

The cake is dry
It was baked for too long or at too high a heat. Stay at 160 °C and start testing with a skewer 5 minutes early. Chocolate sponge shows no obvious colour change, so go by the skewer.
The top is burnt but the middle is raw
The fan browns the surface fast. Lay foil over the cake after 15 minutes and check that the paper does not stick up above the tin.
The cake is domed and cracked
The edges set before the middle. Make a shallow dip in the batter and keep the heat at 160 °C.

Frequently asked questions

How long does chocolate cake take in an air fryer?

About 28 minutes at 160 °C for a 15 cm cake. A 450 g loaf tin takes 30–35 minutes, and a single ramekin cake takes 12–14 minutes at 170 °C.

What is the best tin for chocolate cake in an air fryer?

A deep 15 cm round tin fits most 4–6 litre baskets. An 18 cm tin fits only larger 6 litre baskets with a wide base, so measure your basket first.

Can you make chocolate cake in an air fryer without a tin?

Not easily. The batter is too runny to hold its shape. A silicone mould or a foil container of the right size works instead of a metal tin.

Can I make an air fryer chocolate cake without eggs?

Yes. Replace the 2 eggs with 100 g natural yoghurt and add an extra ½ tsp baking powder. The sponge will be slightly denser but stays moist.

Can you make a chocolate cake for one in an air fryer?

Yes. Use a quarter of the mixture in a greased 200 ml ramekin and cook at 170 °C for 12–14 minutes.
