-
4 large eggs, room temperature
-
⅔ cup (≈ 130 g) granulated sugar
-
½ cup (≈ 65 g) all-purpose flour
-
¼ cup (≈ 25 g) cornstarch (optional — helps keep cake light)
-
1 teaspoon baking powder
-
½ teaspoon vanilla extract
-
2 ripe bananas, mashed (about 1 cup mashed)
-
Pinch of salt
For the Caramel Filling
-
½ cup (≈ 120 g) heavy cream (or equivalent)
-
½ cup (≈ 100 g) brown sugar (or use a caramel sauce of your choice)
-
2 tablespoons unsalted butter
-
1 teaspoon vanilla extract
-
Optional: pinch of salt for salted-caramel flavor
For Finishing

Powdered sugar (for dusting)
-
Whipped cream or extra caramel drizzle (optional)

Sliced bananas for garnish (optional)
Instructions
1. Bake the Banana Sponge
-
Preheat oven to 350 °F (175 °C).
-
Line a rectangular baking sheet (about 9×13 inches) with parchment paper; grease lightly.
-
In a large bowl, beat eggs and sugar together until light, fluffy, and pale (about 3–5 min).
-
Gently fold in mashed bananas and vanilla.
-
In a separate bowl, whisk together flour, cornstarch (if using), baking powder, and salt.
-
Gradually fold the dry mixture into the banana-egg batter until just combined — avoid overmixing.
-
Pour batter evenly into the prepared pan, smoothing the top.
-
Bake for 12–15 minutes, until the cake springs back lightly when touched and looks set but not browned heavily.
2. Roll the Cake (while warm)
-
Once out of the oven, immediately loosen cake edges with a knife.
-
Place a clean kitchen towel on a work surface and dust lightly with powdered sugar.
-
Carefully flip the cake onto the towel (peeling off the parchment).
-
Starting at a short edge, roll the cake together with the towel inside — like a swiss roll.
-
Let it cool completely (rolled) to “set” the shape.
3. Prepare the Caramel Filling
-
In a small saucepan, combine heavy cream, brown sugar, and butter over medium heat.
-
Stir until butter melts and sugar dissolves; bring to a gentle simmer.
-
Let simmer 2–3 minutes until slightly thickened.
-
Remove from heat and stir in vanilla (and salt if using).
-
Let caramel cool to lukewarm (not hot).
4. Assemble the Cake Roll
-
Carefully unroll the cooled sponge.
-
Spread the caramel filling evenly over the surface (leave a small margin around edges).
-
Gently re-roll the cake (without towel), making sure filling stays inside.
-
Place seam-side-down on a serving platter.
5. Finish & Serve
-
Dust the top with powdered sugar.
-
Optionally drizzle extra caramel sauce or top with whipped cream and banana slices.
-
Chill 30 minutes if you like firmer slices.
-
Slice with a sharp knife and serve.
Notes
-
Rolling the cake while it’s still warm — and with a towel — helps prevent cracking and gives a smooth roll.
-
Let the caramel cool before spreading or it may soak into the cake and make it soggy.
-
Handle gently when unrolling and re-rolling to maintain shape.
-
Use ripe bananas for maximum flavor and moisture.
