Crafting Your Banoffee Cake: Step-by-Step Guide

Let’s build this beautiful layer cake. The key is to use very ripe bananas for the best flavor!

1. Bake the Banana Sponges: First, preheat your oven to 180°C/160°C Fan (350°F). Butter and line two 20cm (8-inch) deep springform cake tins. In a large bowl, beat the softened butter and the light brown sugar together until light and fluffy. Beat in the eggs one by one. Mix in the sifted flour, baking powder, and bicarbonate of soda. Finally, stir in the vanilla extract and the mashed ripe bananas until just combined.

1. Cool the Cakes: Divide the batter equally between your two prepared tins and bake for 35 minutes, or until a skewer inserted into the center comes out clean. Let the cakes cool in their tins for at least 10 minutes before transferring them to a wire rack to cool completely.
2. Make the Caramel Buttercream: To make the buttercream, beat the softened butter and the icing sugar together for about 5 minutes, until very light and fluffy. Add the soft cheese and beat for another minute until fully combined. Finally, add the caramel and mix until the buttercream is thick, smooth, and spreadable.
3. Assemble the Cake: Place one of the cooled banana sponges on your serving plate or cake stand. Spread about 50g of the topping caramel over the top, followed by a thick layer of the buttercream. Chill this layer for 10 minutes to help it firm up. Place the second sponge on top. Spread the remaining buttercream over the top and sides of the cake. A “naked” or “semi-naked” style with the sides lightly scraped looks beautiful. Chill the entire cake for at least 30 minutes.

1. Caramelize the Bananas and Decorate: In a bowl, whisk the remaining 100g of caramel with 1 tablespoon of cold water until smooth. Melt the butter in a frying pan and fry the sliced bananas for 2-3 minutes, until they begin to caramelize and turn golden brown. Let them cool slightly, then gently stir them through half of the thinned caramel sauce.
2. The Grand Finale: Pile the caramelized bananas on top of the chilled cake. Drizzle with the remaining caramel sauce and finish with a tiny sprinkle of sea salt flakes, if you like.

Wise Tips for the Best Banoffee Cake

• Use VERY Ripe Bananas: For the moistest cake with the deepest banana flavor, your bananas should be very ripe and covered in brown spots.
• Cool Cakes Completely: You must let your cake layers cool completely to room temperature before you attempt to frost them. A warm cake will melt your beautiful buttercream into a soupy disaster.
• The Chilling Steps are Key: Chilling the first filled layer and then the entire frosted cake is crucial. It helps the buttercream to firm up, making the cake more stable and much easier to slice cleanly.
• What is Carnation Caramel? It’s a thick, ready-made caramel, similar to dulce de leche. You can find it in the baking aisle of most grocery stores.

Frequently Asked Questions (FAQ) – Banoffee Cake

Can I make this cake ahead of time?
Yes. You can bake the cake layers a day in advance, let them cool completely, and store them, well-wrapped, at room temperature. The buttercream can also be made a day ahead and stored in the fridge; just let it come to room temperature and give it a quick whip before frosting the cake. Assemble and add the fresh banana topping the day you plan to serve.

How do I store the finished cake?
The finished cake should be stored in the refrigerator because of the cream cheese buttercream and fresh banana topping. It is best enjoyed within 2-3 days.

Can I make this into a sheet cake?
You could bake the batter in a 9×13 inch pan, adjusting the baking time as needed. Then, you can simply frost the top of the sheet cake and add the caramelized banana topping.

Conclusion

This Banoffee Cake is a true showstopper that is an absolute dream for any banana and caramel lover. It’s a decadent, impressive, and incredibly satisfying dessert that is sure to be the star of any special occasion. Enjoy every single indulgent bite!
