Ingredients for banana banoffee cake
Eight slices of pure indulgence—moist banana cake, boozy caramel swirls, and toasted nuts that’ll disappear too fast.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, about 4 medium bananas |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 1 ½ cups | For cake batter |
| Brown Sugar 🍚 | ½ cup | Packed, for nut topping |
| Unsalted Butter 🧈 | 1 cup | Melted, full-fat preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality |
| Baking Soda 🧂 | 1 tsp | Not baking powder |
| Ground Cinnamon 🌶️ | 1 ½ tsp | Warm spice for depth |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Heavy Whipping Cream 🥛 | 1 cup | Cold, for whipped cream |
| Whipped Cream 🍦 | 2 cups | Store-bought or homemade |
| Dark Rum 🍹 | ¼ cup | For caramel and nut topping |
| Chopped Walnuts 🥜 | 1 ½ cups | Toasted, for crunch |
| Condensed Milk 🥛 | 1 can | 14 oz can, full-fat |
The bananas are the star here—pick ones with brown spots for the best flavor. Trader Joe's or your local grocery store usually has perfect ones. For the flour, King Arthur or Bob’s Red Mill are my go-tos—they bake up lighter. The butter? Full-fat is non-negotiable—it keeps the cake tender. If you’re worried about over-mixing, use a hand mixer on low speed just until combined. And that rum? Any dark rum works, but a good-quality one makes the caramel sing.
No rum? Swap for vanilla extract or orange liqueur—just reduce the amount by half. The walnuts can be pecans or hazelnuts if you prefer, but toast them first—toasting adds insane flavor. For the whipped cream, store-bought is fine, but if you’re feeling fancy, whip the heavy cream with a splash of vanilla and powdered sugar. The condensed milk is key for that classic banoffee texture—don’t skip it. And if you’re worried about the cake being too sweet, the caramel and nuts balance it perfectly.
This cake keeps for 3 days in an airtight container, but honestly? It’s best the first day. The caramel stays gooey, the cake stays moist, and the nuts keep their crunch. For leftovers, wrap tightly with plastic wrap to keep everything fresh. And if you’re making this ahead? Assemble it the night before—the flavors meld beautifully overnight. Trust me, the first slice out of the fridge is worth the wait.

Mash those bananas right into the batter, fold in the butter, and boom: three layers of moist cake with that signature caramelized brown sugar topping. No fancy techniques, no waiting for bananas to soften (they’re already ripe, duh).

I make a double batch on Sundays, and it’s still gone by Wednesday—no sad, dried-out cake here. (Yes, even on a Tuesday night.)
Step-by-step instructions for banana banoffee cake
Here's how to create layers of moist banana cake, boozy caramel swirls, and a crunchy nut topping.
Prepare the Banana Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans. In a large mixing bowl, combine the 2 cups mashed ripe bananas, 1.5 cups granulated sugar, and 1 cup melted unsalted butter. Mix until smooth and creamy—this is your flavor base.
In a separate bowl, whisk together the 2.5 cups sifted all-purpose flour, 1 tsp baking soda, 1.5 tsp ground cinnamon, and 0.5 tsp salt. Gradually add the dry ingredients to the banana mixture while stirring gently. Add the 2 whole eggs, one at a time, mixing just until combined after each addition. Finally, stir in the 2 tsp vanilla extract. The batter should be thick but pourable—if it looks too stiff, add 1 tablespoon of milk to loosen it.
Bake the Cake Layers
Divide the batter evenly between the two prepared cake pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely. This cooling step is crucial—it prevents the cakes from becoming soggy when assembling.
Once cooled, place one cake layer on a serving plate. Spread 1 cup of whipped cream evenly over the top, leaving a ½-inch border around the edges. This will be the base for your caramel swirls. Repeat with the second cake layer, placing it on top of the first.
Make the Boozy Caramel Swirls
In a saucepan, combine the 1 can condensed milk, 0.5 cup brown sugar, and 0.25 cup dark rum. Cook over medium heat, stirring constantly, until the mixture thickens to a caramel-like consistency—this should take about 5-7 minutes. The caramel is ready when it coats the back of a spoon and holds its shape.
Remove the pan from heat and let the caramel cool slightly for 2 minutes. Using a spoon, drizzle the caramel in a spiral pattern over the whipped cream layer, starting from the center and working your way out. The rum adds a rich, boozy depth to the caramel, so don't skip this step—it's what makes this cake truly special.
Prepare the Nut Topping
In a small skillet, toast the 1.5 cups chopped walnuts over medium heat for 3-4 minutes, stirring constantly, until they turn a rich golden brown and release their aroma. This toasting enhances their natural flavor and adds a delightful crunch to the cake.
In a separate bowl, mix the toasted walnuts with 1 cup heavy whipping cream until the nuts are evenly coated. Spread this mixture evenly over the caramel swirls, creating a beautiful, textured topping. The contrast between the creamy caramel and the crunchy nuts is what makes this cake unforgettable.
Chill and Serve
Refrigerate the cake for at least 4 hours, or preferably overnight, to allow all the flavors to meld together. This chilling time ensures that the caramel sets properly and the cake holds its shape when sliced. Before serving, dust the top with a little extra ground cinnamon for a final touch of warmth.
Slice the cake into 8 equal wedges and serve chilled. Each bite will deliver layers of moist banana cake, rich caramel, and a perfect balance of creamy and crunchy textures. Trust me, this cake is worth every step!
Pro Tips For Making Banana Banoffee Cake
- Bake at 325°F: I learned this the hard way—hotter temps make the cake rise fast but then collapse. The butter in this recipe needs time to melt evenly, and 325°F guarantees a tender crumb without a dense center.
- Mash bananas thoroughly: No one likes surprise banana chunks in their cake. Use a fork to crush them completely, then press through a sieve if you’re lazy about mixing. Smooth batter = even texture.
- Don’t overmix the batter: This isn’t pancakes. Stir just until the flour disappears—overmixing makes the cake tough. A few lumps? Doesn’t matter. A dense, rubbery texture? That’s what you get when you go overboard.
- Use cold butter for layers: Skip the softened butter in the toffee sauce—it makes the caramel runny and hard to spread. Whisk cold butter into the brown sugar until it’s crumbly, then bake as directed. The contrast keeps the toffee firm and flavorful.
Perfect pairings for these flavors
Coffee Pairings
This cake's rich caramel and boozy notes pair beautifully with medium-roast coffee like a French Roast or Sumatra. The coffee's bitterness cuts through the sweetness while enhancing the rum's warmth. I love serving it with a cappuccino—the froth adds a creamy contrast. ☕
Tea Companions
For a lighter pairing, try Earl Grey tea with its bergamot notes—it complements the cake's vanilla and nutty flavors without overpowering. A chilled jasmine green tea also works wonderfully, especially if you serve the cake chilled. The floral notes balance the caramel's richness.
Alcohol Pairings
Since the cake already has rum, serve it with Baileys Irish Cream for a cozy dessert experience. The coffee liqueur's smoothness mirrors the caramel's depth. For something lighter, a dry sparkling wine like Prosecco adds a refreshing contrast to the cake's richness. 🍷
Seasonal Serving Suggestions
In summer, serve the cake chilled with a scoop of vanilla bean ice cream—the cold temperature makes it even more decadent. For holiday gatherings, dust the top with powdered sugar and add a sprinkle of crushed peppermint for a festive twist.
Creamy Contrasts
Add a dollop of vanilla ice cream or whipped cream alongside each slice for an extra layer of indulgence. The cold cream balances the cake's warm spices and caramel. I also love serving it with a drizzle of chocolate sauce on the side for guests to customize their slices. 🍦
Fruit Accompaniments
Fresh strawberries or raspberries add a bright, tangy contrast to the cake's sweetness. Arrange them around the plate for a visually stunning presentation. The acidity in the berries also helps cleanse the palate between bites.

Frequently asked questions
Can I make this banana banoffee cake without rum?
Replace the 0.25 cup dark rum with 1 teaspoon vanilla extract or 0.125 cup orange liqueur for a similar depth of flavor. The caramel will still be rich and delicious, just without the boozy kick. For a non-alcoholic option, try a splash of almond extract instead.
How do I know when the caramel is done?
The caramel is ready when it thickens to a glossy, spoonable consistency that coats the back of a spoon and holds its shape. It should take about 5-7 minutes of constant stirring over medium heat. If it starts to brown too quickly, reduce the heat slightly—you want it smooth, not burnt.
Can I use a different type of nut for the topping?
Yes! While walnuts are classic, you can swap them for pecans, hazelnuts, or even almonds. Just be sure to toast them first—this enhances their flavor and adds that perfect crunch. Pecans add a buttery note, while hazelnuts bring a slightly earthy twist.
Why does my cake look dry after baking?
Overbaking or under-mixing the batter are common culprits. Always check for doneness with a toothpick (25-30 minutes at 350°F), and avoid overmixing the batter—just combine until smooth. For extra moisture, brush the cooled layers with a simple syrup (equal parts sugar and water, heated and cooled) before assembling.
Can I make this cake in a single layer instead of two?
Yes! Use a 9x13-inch pan and bake for 35-40 minutes until set. After cooling, spread 1 cup whipped cream over the entire layer, then drizzle the caramel in a zigzag pattern. Top with the nut mixture and chill as directed. The single layer is perfect for feeding a crowd.
