I make this Banoffee Cake when I want something indulgent, comforting, and guaranteed to impress. It combines soft banana cake layers with a rich homemade toffee filling, fresh banana slices, and a smooth vanilla frosting. Every bite reminds me of classic banoffee pie, but in a stunning layered cake form that feels perfect for celebrations.
Why You’ll Love This Recipe
I love how this cake balances flavors and textures so beautifully. The banana layers stay incredibly moist, while the homemade toffee adds a deep caramel richness that melts into every bite. The frosting is light and creamy, which keeps the cake from feeling too heavy. I also enjoy how customizable it is, whether I add chocolate chips or keep it purely classic. It’s a show-stopping dessert that always feels worth the effort.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
14 oz sweetened condensed milk, label removed
1 1/2 cups ripe bananas, mashed
2 tsp lemon juice
3 cups all-purpose flour
1 tsp baking powder
1 tsp baking soda
1/2 tsp fine salt
1 cup unsalted butter, room temperature
1 cup granulated sugar
2/3 cup packed light brown sugar
3 large eggs, room temperature
2 tsp vanilla extract or vanilla bean paste
1 1/2 cups buttermilk, room temperature
3/4 cup mini chocolate chips or chopped chocolate, optional
2 cups unsalted butter, room temperature
3 Tbsp heavy whipping cream, room temperature
2 tsp vanilla extract or vanilla bean paste
1/2 tsp fine salt
6 cups powdered sugar
1/4 cup pasteurized egg whites, optional
4 to 5 fresh bananas, optional
Directions
I start by making the toffee. I place the unopened, label-free can of sweetened condensed milk in a large pot, cover it with water, and let it simmer gently for about 2 hours. I keep an eye on it and add water when needed. Once done, I let it cool completely before opening.
Next, I preheat the oven to 350°F (175°C) and prepare three 8-inch cake pans by greasing and lining them.
I mash the bananas and mix them with lemon juice to keep them fresh. In one bowl, I whisk together the flour, baking powder, baking soda, and salt. In another bowl, I beat the butter with both sugars until the mixture becomes light and fluffy.
I add the eggs and vanilla, then mix in half of the dry ingredients, followed by the buttermilk, and then the remaining dry ingredients. I gently fold in the mashed bananas and chocolate chips if I decide to use them.
Then I divide the batter evenly into the pans and bake for 28 to 32 minutes. Once baked, I let the layers cool completely.
For the frosting, I beat the butter until pale and fluffy, then mix in the cream, vanilla, and salt. I gradually add powdered sugar and whip everything together until smooth and airy, finishing with egg whites if I want extra fluffiness.
To assemble, I place the first cake layer down, spread frosting on top, and pipe a border around the edge. I chill it briefly, then fill the center with toffee and banana slices. I repeat this process for all layers.
I apply a thin crumb coat, chill the cake, then finish with a thicker layer of frosting. For decoration, I like to add a drizzle of toffee and top it with banana slices or chips.

Variations
I sometimes switch things up depending on my mood. I like adding a layer of chocolate ganache for a richer twist, or I mix espresso into the toffee for a subtle coffee flavor. When I want a lighter version, I skip the chocolate chips and focus on the banana and caramel notes. I also enjoy turning this into cupcakes for easier serving.
Storage/Reheating
I store the cake in the refrigerator because of the fresh bananas and frosting. I keep it covered to prevent it from drying out, and it usually stays fresh for up to 3 days. Before serving, I let it sit at room temperature for a bit so the frosting softens and the flavors come through better. I don’t recommend reheating, as this cake is best enjoyed chilled or slightly softened.

FAQs
Can I make the toffee ahead of time?
I often make the toffee a day or two in advance and store it in the fridge. It saves time and lets me focus on baking and assembling later.
Can I use store-bought dulce de leche instead?
Yes, I sometimes use store-bought dulce de leche when I’m short on time. It works well and still gives that rich caramel flavor.
How do I keep the bananas from browning?
I always toss the banana slices in a little lemon juice before layering. It helps keep them fresh and visually appealing.
Can I freeze this cake?
I prefer freezing the cake layers without filling. Once thawed, I assemble with fresh bananas and frosting for the best texture.
What can I use instead of buttermilk?
When I don’t have buttermilk, I mix milk with a bit of lemon juice or vinegar and let it sit for a few minutes. It works just as well in this recipe.
Conclusion
I find this Banoffee Cake to be one of the most satisfying desserts to make and serve. It brings together comforting banana flavors, rich toffee, and creamy frosting in a way that feels both nostalgic and special. Whenever I bake it, it quickly becomes the centerpiece of any gathering and always leaves people asking for another slice.
