Why you'll love this air fryer lava cake
There is something magical about a lava cake, the warm exterior breaking open to reveal a molten chocolate centre, and you do not need an oven or hours of prep.
- Ready in under 10 minutes
- Minimal ingredients, most you already have
- Single-serve and small-batch friendly
- No oven needed, ideal for warm weather
- Looks fancy but is genuinely easy
Ingredients you'll need
- 4 oz semi-sweet or dark chocolate (a bar melts more smoothly than chips)
- ¼ cup unsalted butter (half a stick)
- 1 large egg
- 1 egg yolk
- 2 tablespoons granulated sugar
- 2 tablespoons all-purpose flour
- 1 teaspoon vanilla extract (optional)
- Pinch of salt
Optional add-ins: ¼ teaspoon espresso powder to deepen the chocolate flavour, powdered sugar for dusting, and vanilla ice cream, berries, or whipped cream to serve.
How to make air fryer lava cake
- Preheat. Set the air fryer to 375°F (190°C) and let it heat for 3 to 5 minutes. The hot start sets the outside quickly while the centre stays runny.
- Melt chocolate and butter. In a microwave-safe bowl, heat the chocolate and butter in 20-second bursts, stirring each time, until smooth. A double boiler works too. Let it cool slightly.
- Mix the wet ingredients. In another bowl, whisk the egg, egg yolk, sugar, vanilla and salt until slightly frothy.
- Combine. Pour the melted chocolate into the egg mixture in a slow stream while whisking, so the eggs do not scramble. Stir in the flour just until combined. Do not overmix.
- Prepare the ramekins. Grease two air fryer-safe ramekins with butter, then dust the insides with cocoa powder and tap out the excess. Cocoa instead of flour means a clean release with no pale streaks on a chocolate cake. Divide the batter evenly.
- Air fry. Place the ramekins in the basket and cook at 375°F for 6 to 8 minutes. The tops should be set but still slightly jiggly in the centre. A shorter time gives a runnier centre, a longer time a firmer one.
- Cool, invert, and serve. Rest 1 to 2 minutes, run a knife around the edges, then invert onto a plate. Dust with powdered sugar, add ice cream, and serve right away.
Tops browning too fast? If your air fryer runs hot and the tops set or crack before the centre is ready, lay a small piece of foil loosely over the ramekins for the first few minutes, then remove it to finish. See how to prevent burning in the air fryer.

How to tell when lava cake is done
This is the part that matters most, do not overbake or you lose the gooey centre.
- The edges should be firm and set.
- The centre should jiggle slightly when you gently shake the ramekin.
- Do not use a toothpick test, it will always come out gooey in the middle.
- Start checking at the 6-minute mark.
Delicious variations
- Nutella lava cake: drop 1 teaspoon of Nutella into the centre before air frying.
- Peanut butter: tuck a dollop of peanut butter into the middle.
- White chocolate: use white chocolate instead of dark.
- Vegan: use dairy-free chocolate, coconut oil, and a flax egg.
- Gluten-free: swap the flour for almond flour or a 1:1 GF blend.
Tips for the best lava cake
- Use good chocolate. It is the heart of the dessert, so pick one you would happily eat on its own. A bar melts more smoothly than chips, which contain stabilisers.
- Do not overbake. The centre should stay molten.
- Grease and cocoa-dust the ramekins so the cakes release cleanly.
- Use room-temperature eggs for a smoother batter and better rise.
- Preheat the air fryer so the outside sets while the inside stays runny.
- Serve immediately, they are at their best warm.
Optional hack: chill the filled ramekins for 15 to 20 minutes before air frying for even firmer edges and a more dramatic molten centre.
What to serve with lava cake
It is wonderful on its own, but even better with a scoop of vanilla ice cream that melts into the warm cake, fresh raspberries or strawberries, a drizzle of caramel or raspberry sauce, whipped cream dusted with cocoa, or chopped nuts for crunch.
Common mistakes to avoid
- Overcooking, which turns your lava cake into a brownie.
- Using too much flour, which dries out the centre. Spoon and level it.
- Not greasing the ramekins, so the cake sticks and breaks.
- Skipping the preheat, which causes uneven cooking.
Storing and reheating
Lava cakes are best fresh, but if you have leftovers, let them cool completely and store in an airtight container in the fridge for up to 2 days. The molten centre will firm up as it chills.
To reheat: warm in the air fryer at 320°F for about 2 minutes, or microwave for 20 to 25 seconds. The centre may set slightly.
To freeze: wrap cooled cakes in plastic and foil and freeze for up to 1 month. Thaw overnight in the fridge before reheating.
Frequently asked questions
QCan I make lava cake without ramekins?
Yes. Use silicone moulds or oven-safe mugs instead. The bake time may vary slightly, so start checking at 6 minutes.
QCan I use boxed cake mix?
Not for lava cakes. You need a higher fat ratio and less flour than a boxed mix provides to get that molten centre.
QCan I make mini lava cakes?
Yes. Use smaller moulds and reduce the air frying time by 1 to 2 minutes, checking early so the centre stays runny.
QCan I make these ahead?
Yes. Prep the batter, fill the ramekins, and refrigerate up to 24 hours. Let them sit at room temperature for 10 to 15 minutes, then air fry just before serving.
QWhy did my lava cake set in the middle?
It cooked too long. Air fryers vary, so next time check at 6 minutes and pull the cakes while the centre still jiggles. A shorter cook keeps the centre runny.
