- 1/2 cup (95g) packed dark brown sugar
- 6 tablespoons (75g) granulated sugar
- 1 tablespoon molasses or treacle
- 1 teaspoon vanilla extract
- 2 large eggs
- 2/3 cup (170g) mashed bananas (about 2 medium, very ripe)
- 1/2 cup (120ml) well-shaken buttermilk
- 1 teaspoon baking powder
- 3/4 teaspoon baking soda
- 1 3/4 cups (230g) all-purpose flour

- 4 tablespoons (55g) unsalted butter, cold is fine

How to Make the Banana Toffee Cake
Prepare the Banana Cake Batter
- Heat your oven to 350°F (175°C). Generously butter or coat 12 muffin cups with nonstick spray for easy release.
- In a large mixing bowl, whisk together the melted butter, salt, brown sugar, granulated sugar, molasses, and vanilla until the mixture is smooth and combined.
- Add the mashed bananas and whisk until fully blended. Next, add the eggs and whisk until well incorporated.
- Whisk in the buttermilk. Then, sprinkle the baking powder and baking soda evenly over the batter and whisk thoroughly—about 10 to 20 strokes—to ensure they are well dispersed before adding the flour.
- Add the flour and stir gently, mixing just until no dry streaks remain. Do not overmix.
- Divide the batter evenly among the prepared muffin cups.
Bake
- Bake for 14 to 16 minutes, or until a toothpick inserted into the center of a cake comes out clean (without wet batter clinging).
- Remove from the oven and let cool in the pan for several minutes before serving or finishing with toppings.
Making the Toffee Sauce
While the cakes are baking, prepare the silky toffee sauce. This step comes together quickly, so have all ingredients measured and ready before starting.
- Combine the cold butter, half of the heavy cream (1/2 cup/120ml), and brown sugar in a medium or large saucepan (choose a size bigger than you expect, as sauce foams as it simmers).
- Stir over medium-high heat until everything is melted and beginning to simmer.
- Continue simmering for 5–7 minutes, whisking frequently. The sauce will thicken slightly.
- Add a couple of pinches of flaky sea salt and vanilla. Stir to combine. Remove from heat when the sauce coats the back of a spoon.
Preparing the Whipped Cream
- In a medium mixing bowl, whisk or beat the remaining 1/2 cup (120ml) heavy cream until soft peaks form. Do not add sugar; the toffee sauce provides sufficient sweetness.
- Refrigerate the whipped cream if not serving immediately. For best results, whip fresh, but pre-whipped cream can keep for hours or use stabilization techniques for longer storage.
How to Serve
Serving this cake is as appealing as enjoying it:
- Remove each warm cake from the muffin tin. Place dome-side up, or slice off the dome for a flat base and serve upside-down.
- Ladle each cake generously with warm toffee sauce. Finish with a big dollop of unsweetened whipped cream and a sprinkle of flaky sea salt for contrast and sophistication.
- Optional: Use domes sliced from the cakes for sampling or to satisfy hungry kitchen helpers.
Make Ahead and Storage Tips
- Cake: Stays fresh for 3 to 4 days at room temperature in an airtight container. Gently reheat before serving for best texture and flavor.
- Toffee Sauce: Keeps for 1–2 weeks in the refrigerator. Reheat gently in the microwave (about 20 seconds) or on the stovetop until liquid again.
- Whipped Cream: Can hold for several hours refrigerated. For longer keeping, stabilize with a spoonful of crème fraîche or mascarpone.
Expert Tips and Variations
- Use Overripe Bananas: The riper your bananas, the deeper the flavor of the finished cake.
- Customize Toppings: Add toasted nuts or fruit for extra texture. Sliced bananas or toasted pecans make beautiful garnishes.
- Single Cake Variation: Bake as a single 8×8-inch square, but adjust baking time to up to 30–35 minutes.
- Serve Warm: All components are best enjoyed warm, especially the toffee sauce, so rewarm as needed for the coziest experience.
- Gluten-Free Option: Substitute a 1:1 gluten-free flour blend for the all-purpose flour; check for doneness a few minutes earlier.
FAQs: Banana Toffee Cake
What’s the best type of banana for this recipe?
Use very ripe bananas with brown spots—they’re sweeter and mash more easily, lending moisture and flavor to the cake.
Can I make this as a single cake instead of individual servings?
Absolutely. Bake the batter in a greased 8×8-inch (20x20cm) pan, and extend the baking time to 30–35 minutes. Cool slightly, then cut into squares and serve as directed.
How can I store leftover cake?
Store at room temperature in an airtight container for up to 4 days. To refresh, rewarm briefly before adding sauce and cream to regain moisture.
Is the toffee sauce overly sweet?
No. The cake and sauce are both rich and caramel-forward, but the unsweetened whipped cream and sea salt balance overall sweetness perfectly.
Can I freeze the banana cake?
You can freeze the baked, plain cakes. Thaw at room temperature, then warm before topping. Freeze sauce and cream separately for best results.
