Air Fryer Lava Cake delivers the perfect combination of a tender cake exterior and a luxuriously gooey chocolate center. The batter is so tempting you might be tempted to lick the spatula—guilty pleasure encouraged. While they say you can’t have your cake and eat it too, this recipe proves otherwise.
These molten chocolate cakes are ideal for Valentine’s Day, but you don’t need a special occasion to enjoy something this decadent. Crisp on the outside and molten inside, the air fryer method produces an indulgent dessert in minutes. It’s simple, satisfying, and easily customizable, so it may become one of your favorite treats.
One of the best features of this recipe is how well it adapts to advance prep. Prepare the batter a day ahead and store it in the refrigerator. Remove it 30 minutes before cooking, stir lightly, portion into ramekins, add your chosen filling, and cook when ready.
Making lava cake in the air fryer is especially handy on hot days when you want to avoid heating the oven. The basic batter is straightforward to prepare and opens the door to many flavorful fillings. With the same chocolate batter you can make classic chocolate, Nutella, caramel, or peanut butter lava cakes—each pairing beautifully with the chocolate base. Feel free to mix and match fillings for a dessert variety.

Below are the primary ingredients for this easy recipe. For exact measurements and a printable recipe card, see the recipe section further down.
- Butter: Unsalted, cut into cubes.
- Semi-sweet chocolate: Use a chocolate bar or chips; bittersweet also works.
- Large egg
- Large egg yolk
- White sugar
- Brown sugar: Light or dark, your choice.
- Coffee: Liquid coffee or a shot of espresso for depth of flavor.
- Vanilla extract: Pure, for best flavor.
- All-purpose flour
- Pinch of salt
How to make air fryer lava cake
- Prepare: Grease three 6-ounce ramekins with butter or nonstick spray and set aside.
- Melt the chocolate: Combine butter and chopped chocolate in a microwave-safe bowl. Heat about 1 minute, stirring every 30 seconds, until smooth. Set aside to cool slightly.
- Mix wet ingredients: In a separate bowl, beat the egg, egg yolk, sugars, and vanilla with an electric mixer until well combined, about 2 minutes.
- Combine: Fold the melted chocolate and a pinch of salt into the egg mixture, then gently add the flour. Stir with a spatula until just combined—do not overmix.
- Fill ramekins: Spoon the batter into the prepared ramekins, filling each a little more than halfway.
- Air fry: Preheat the air fryer to 370°F (188°C). Arrange the ramekins in the basket and cook 8–10 minutes, until the edges are set and the center remains slightly soft.
- Cool and unmold: Remove ramekins with oven mitts and let cool 1 minute. Run a butter knife around the edges, cover each ramekin with a plate, invert, and tap gently to release the cakes.
- Serve: Dust with powdered sugar and serve with ice cream, whipped cream, or fresh berries.
Recipe variations
- Nutella lava cake: For the filling, mix 2 tablespoons Nutella with 1 tablespoon softened butter and 1 tablespoon powdered sugar. Place a tablespoon of this mixture in the center of each ramekin before topping with batter.
- Peanut butter lava cake: Combine 2 tablespoons peanut butter, 1 tablespoon softened butter, and 1 tablespoon powdered sugar for a creamy peanut butter center.
- Caramel lava cake: Use 2 tablespoons of caramel sauce as the filling for a buttery, sweet center.
- Cocoa option: If you prefer, use cocoa powder instead of chopped chocolate. The flavor will be slightly lighter and the texture a bit less rich.
- Dark chocolate: Substitute dark chocolate for a more intense, slightly bitter profile.
- Flavor twist: Add an extra teaspoon of vanilla or swap vanilla for a rum extract for a unique aroma; chopped pecans stirred into the filling add crunch.
Make lava cakes in the Instant Pot
- Prepare the batter and chosen fillings as directed.
- Add a trivet to the inner pot and pour in 1 1/2 cups of water.
- Place the filled ramekins on the trivet, close the lid, and set the valve to “sealing.”
- Pressure cook on high for 8 minutes, then perform a quick release.
- Carefully remove ramekins with oven mitts, invert onto plates, and tap gently to release the cakes. Let cool briefly, dust with powdered sugar, and serve with ice cream.
Make lava cakes in the oven
- Prepare batter and fillings as directed.
- Spoon batter into prepared ramekins and preheat the oven to 450°F (232°C).
- Arrange ramekins on a baking sheet and bake 10–12 minutes, until the sides are set and the centers remain soft. Remove and let cool 1 minute.
- Loosen edges with a knife, invert onto plates, and gently tap to release. Dust with powdered sugar and serve warm with ice cream.
How to serve
These lava cakes are splendid with a scoop of vanilla ice cream, a dusting of powdered sugar, or fresh berries. Other serving ideas:
- A dollop of whipped cream for a light, creamy finish.
- A sprinkle of chopped walnuts or pecans for contrast in texture.
- Serve alongside a warm mug of hot chocolate for a double chocolate experience.
- Top with cream cheese frosting or a spoonful of strawberry sauce for a fruity counterpoint.
Frequently asked questions
How do I know when my lava cake is done?
The center should remain molten, so a toothpick test isn’t reliable. Look for fully set edges and a risen center that feels slightly soft but not jiggly. Time and one test batch will help you dial in the perfect cook time for your air fryer.
What is a lava cake?
A lava cake is a small chocolate cake with a molten, flowing center. The outside sets while the inside remains gooey because of the short cooking time. If you prefer a temperature check, the center should reach about 160°F (71°C).
Why did my lava cake fall?
If the top sinks instead of holding a slight dome, the batter may have been overmixed, which incorporates too much air. Mix only until ingredients are combined and bake immediately to prevent collapse.
How to store leftovers
- Refrigerate: Cool to room temperature, then store in an airtight container in the refrigerator for 3–4 days.
- Freeze: For longer storage, freeze individual cakes for up to 3 months.
- Thaw: Defrost overnight in the refrigerator.
- Reheat: Warm in the air fryer for about 3 minutes to revive the molten center.
Cooking tips
- Use 6-ounce ramekins for the cook times listed; adjust timing for different sizes.
- Avoid overbaking to keep the centers molten.
- Run a butter knife around the rim before unmolding to help release the cake.
- Use a double boiler to melt chocolate if you prefer low, gentle heat.
- To make a single larger cake, pour batter into a round pan and bake 10–12 minutes, watching closely for doneness.
