🛒 Ingredients

12 servings

12
  • 3 large eggs
  • ½ cup (120 ml) coconut oil or neutral vegetable oil
  • ½ cup (120 ml) water
  • 2 cups (180 g) rolled oats
  • ½ cup (50 g) unsweetened cocoa powder
  • ½ cup (100 g) raw cane sugar or light brown sugar
  • 1 tablespoon baking powder

Directions

  1. 1

    Preheat your oven to 410 °F (210 °C).

  2. 2

    Place the eggs, oil, water, rolled oats, cocoa powder, and sugar into a blender. Blend on high for 1–2 minutes until the batter is smooth and creamy.

  3. 3

    Add the baking powder and gently fold it in with a spatula — do not blend again, to preserve the rise.

  4. 4

    Grease a 9-inch (22 cm) cake pan and dust with cocoa powder to prevent sticking, then pour in the batter.

  5. 5

    Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.

  6. 6

    Cool in the pan for 10 minutes before unmolding. Serve warm or at room temperature.

💡 Chef's Tip

Swap the water for oat or almond milk for a richer, creamier texture. Fold in a handful of dark chocolate chips before baking for an extra indulgent bite.
