🛒 Ingredients

1 servings

1
  • 1 egg
  • 3 tablespoons warm water
  • 2 tablespoons unsweetened cocoa powder
  • 4 tablespoons brown sugar
  • 4 tablespoons all-purpose flour
  • 2 teaspoons baking powder
  • 2 tablespoons vegetable oil
  • 1 pinch of salt

Directions

  1. 1

    In a large, heat-safe mug, combine the egg and brown sugar. Whisk vigorously with a fork until the mixture is smooth and slightly frothy.

  2. 2

    Dissolve the cocoa powder in the warm water, stirring until completely smooth, then pour into the mug and mix well to combine.

  3. 3

    Sift the flour and baking powder directly into the mug. Gently fold together until just incorporated — avoid overmixing to keep the cake light.

  4. 4

    Add the vegetable oil and a pinch of salt. Stir until the batter is smooth and glossy.

  5. 5

    Preheat your air fryer to 320 °F (160 °C) for 5 minutes.

  6. 6

    Place the mug in the air fryer basket and cook for 15 minutes at 320 °F (160 °C). The cake is done when the top is set but the center is still slightly moist and fudgy — check with a toothpick.

💡 Chef's Tip

For a molten lava effect, press a few dark chocolate chips into the center of the batter before air frying. A teaspoon of vanilla extract or a pinch of espresso powder will deepen the chocolate flavor beautifully. Make sure your mug is oven-safe and fits comfortably in your air fryer basket.
