Air Fryer Recipe
Chocolate lava cakes
Chocolate lava cakes are a dessert lover's dream with molten centers and soft exteriors, easily made in an air fryer.
Ingredients
- 100g dark chocolate, ideally 70% cocoa solids
- 100g unsalted butter
- 150g icing sugar
- 2 large eggs
- 2 large egg yolks
- 50g plain flour
- 1 teaspoon vanilla extract
- Pinch of salt
- Butter and cocoa powder for greasing
Method
- Preheat air fryer to 200°C (392°F).
- Melt chocolate and butter together, stir until smooth, and cool slightly.
- Whisk eggs, egg yolks, vanilla extract, and icing sugar until light and fluffy.
- Fold in melted chocolate and butter mixture.
- Gently fold in flour and salt, ensuring no lumps.
- Grease ramekins with butter and dust with cocoa powder.
- Pour batter into ramekins, filling each about 3/4 full.
- Place ramekins in air fryer basket, ensuring they're not touching.
- Air fry for about 8 minutes until edges are firm but centers remain soft.
- Remove ramekins from air fryer, cool slightly, invert onto plates, and serve immediately.
Why this works in an air fryer
The air fryer’s fast convection sets the outside batter quickly while the ramekin and butter-rich chocolate centre lag behind, giving a cooked shell and molten core. Icing sugar dissolves readily for a smooth crumb, while minimal flour and gentle folding limit gluten so the cake stays tender rather than bready.
Equipment notes
Assumes 4 x 150ml ramekins in a 5–6 litre basket with space for air to circulate; in a small single-drawer cook 2 at a time and start checking at 7 minutes, while dual-zone models often run slightly cooler per drawer, so place ramekins centrally and allow 1–2 minutes extra if both drawers are running.
Common pitfalls
- Centre fully set and sponge-like when cut? It has gone past the lava stage; reduce the next batch by 1–2 minutes or use slightly narrower/deeper ramekins so the middle heats more slowly.
- Cake collapses or leaks before unmoulding? The edges were not set enough; give it another 45–60 seconds until the rim looks matte and slightly pulled from the ramekin but the centre still has a soft wobble.
- Sticking in patches with torn sides? The ramekin coating was incomplete; brush butter upwards in vertical strokes, chill briefly if possible, then dust thoroughly with cocoa rather than flour to avoid pale marks.
- Dry, cracked tops by minute 8? The air fryer is running hot or the ramekins are too close to the heating element; drop to 190°C and check from minute 6, especially in shallow baskets.
Variations & substitutions
- Swap dark chocolate for 50–60% chocolate for a sweeter, softer set; check 30–60 seconds earlier as the higher sugar content can make the centre looser.
- Add 1 teaspoon instant espresso powder to the melted chocolate; it deepens the cocoa flavour without changing the cooking time.
- Use orange zest or 1 tablespoon orange liqueur in the batter; the added liquid makes the centre slightly more fluid, so allow an extra 30 seconds if it looks too loose at the edge.
- For a salted caramel centre, push a small frozen caramel into each filled ramekin; cook as normal but expect a hotter, runnier core, so rest for 1–2 minutes before turning out.
Storage & reheating
Best served immediately, but covered cooked cakes keep in the fridge for up to 2 days; reheat in the ramekin in the air fryer at 160°C for 3–4 minutes, noting the centre will be less molten than freshly cooked.
