Ingredients

1/2 cup unsalted butter, melted and slightly cooled
1 tablespoon water

2 cups milk, lukewarm
4 eggs, separated

3/4 cup sugar
2 tablespoons light brown sugar

1/2 cup mashed banana (about 1 medium banana)
1 cup flour
1 teaspoon vanilla extract

Powdered sugar for dusting

Instructions

Step 1: Preheat the oven to 325°F. Lightly grease an 8×8 inch baking dish or line it with parchment paper, leaving sides to overhang for easy removal.
Step 2: Whip the egg whites until stiff peaks form, then set aside.

Step 3: In a separate bowl, beat the egg yolks with both sugars until the mixture is pale yellow.
Step 4: Add the melted butter and water to the yolk mixture, mixing for about 2 minutes until combined.
Step 5: Stir in the mashed banana until just combined.

Step 6: Gradually mix in the flour until evenly incorporated.
Step 7: Slowly beat in the lukewarm milk and vanilla extract until the batter is smooth.
Step 8: Gently fold in the egg whites in thirds, careful to keep the batter light. Note that the batter will be very thin.

Step 9: Pour the batter into the prepared pan and bake for 45–60 minutes. Start checking at 45 minutes; the cake should be barely jiggly in the center. Cover with foil if the top browns too quickly.
Step 10: Allow the cake to cool completely before dusting with powdered sugar. The cake will remain slightly jiggly in the center due to its custard layer.

Tips & Variations

Using slightly underripe bananas with spots enhances the natural sweetness and flavor of the cake.

For easier serving, line the pan with parchment paper, allowing you to lift the cake out in one piece.
If you prefer, add a pinch of cinnamon or nutmeg to the batter for a warm spice note.
Ensure the milk is lukewarm to prevent curdling when combining with eggs.

Storage

Store the cake in an airtight container in the refrigerator for up to 3 days. Because of its custard-like center, this cake is best served chilled or at room temperature. Reheat gently in a warm oven if desired, but avoid microwaving to preserve texture.

How to Serve

The image shows several square pieces of banana cake on a black surface sprinkled with powdered sugar. Each piece has three visible layers: a dense, creamy beige bottom layer, a thick, smooth middle layer of pale cream filling, and a top layer of golden brown cake dusted lightly with powdered sugar. The texture of the top layer looks soft and slightly crumbly, the middle layer is creamy and smooth, and the bottom layer appears moist and dense. Some small banana slices are scattered near the cake pieces. The background is blurred, focusing attention on the cake squares in the foreground. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use ripe bananas for this cake?

Yes, ripe bananas are ideal as they provide natural sweetness and moisture, giving the cake its rich banana flavor.

Why is the batter so thin?

The batter is thin because it creates the magic layered texture during baking—custard at the center with a cake layer on top and bottom. It’s normal and necessary for this recipe.
