🛒 Ingredients

12 servings

12
  • 3 eggs
  • 2 cups sugar (for the batter)
  • 1 cup milk
  • 1/2 cup vegetable oil
  • 2 cups all-purpose flour
  • 1 tablespoon baking powder
  • 3/4 cup sugar (for the caramel)
  • 1/2 cup hot water
  • 3 to 4 ripe bananas, sliced lengthwise

Directions

  1. 1

    Make the caramel: melt 3/4 cup sugar in a saucepan over medium heat, stirring gently. Carefully add the hot water and let it reduce slightly until you have a smooth, fluid caramel.

  2. 2

    Pour the hot caramel only into the bottom of a greased and floured cake pan (no tube pan). Lay the banana slices lengthwise over the caramel. Set aside.

  3. 3

    In a blender, combine the eggs, 2 cups of sugar, and oil. Blend until smooth and well combined.

  4. 4

    Add the milk and blend again. Gradually add the flour with the blender running to prevent lumps.

  5. 5

    Add the baking powder last and blend very briefly — just enough to incorporate it. Do not over-blend.

  6. 6

    Gently pour the batter over the bananas in the pan. Bake at 400°F (200°C) for 30 to 40 minutes, until a toothpick inserted in the center comes out clean.

  7. 7

    Let the cake rest for 5 to 10 minutes, then unmold by flipping it onto a serving plate. The caramelized bananas will be beautifully displayed on top.

💡 Chef's Tip

Apply caramel only to the bottom of the pan — buttered and floured sides are enough — to keep the sweetness balanced. The riper the bananas, the more fragrant and flavorful the result.
