Ingredients for banana bread cake recipe uk

Ripe bananas, warm spices, and buttery streusel—these UK pantry staples create a showstopping cake.

The bananas are the star, so go for the spotted, mushy ones—they're sweeter and more flavorful. Tesco or Sainsbury's usually have them at the back of the fruit section. For the flour, self-raising is a must—it's the UK standard and saves you the hassle of adding baking powder. The butter? Use a good quality brand like Anchor or McConnell's—none of that margarine nonsense. Toast the walnuts for the streusel (5 minutes in a dry pan) to bring out their flavor, but don't burn them. I always double-check my spices—if your nutmeg smells stale, toss it and buy a tiny jar from Waitrose or M&S—their spice selection is surprisingly good.

No self-raising flour? Use all-purpose plus 2 tsp baking powder per cup. Short on walnuts? Pecans or almonds work too, but toast them first. The streusel can be made ahead and kept in the fridge for 3 days—just bring it to room temp before mixing. Milk substitute? Oat milk works in a pinch, but it'll make the cake slightly denser. Want more banana flavor? Add 1 tsp banana extract (found in baking aisles). The icing sugar is just for dusting—skip it if you prefer a rustic look. For a boozy twist, add 1 tbsp rum or bourbon to the cake batter.

This cake keeps beautifully for 4-5 days in an airtight container at room temperature. If you're making it ahead, bake it 1 day before serving—the flavors deepen overnight. Store any leftovers in the fridge for up to 1 week, but bring it back to room temp before serving. The streusel topping stays crisp for 2 days if kept sealed. For a fancy touch, serve with clotted cream or custard—it's a proper British tea-time combo. Freezing? Wrap tightly and it'll keep for 3 months, but the streusel might lose its crunch slightly.

Step-by-step instructions for spiced banana bread cake with buttery streusel

Here's how to create layers of moist banana cake with a crunchy walnut streusel topping—every bite is pure comfort.

Preheat your oven to 350°F and grease two 8-inch round cake pans or line them with parchment circles. In a large mixing bowl, mash the 3 medium ripe bananas until completely smooth—no lumps! I like to press them through a sieve to remove any skins, which keeps the texture silky.

In a separate bowl, whisk together the 2.5 cups self-raising flour, 2 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. This dry mix ensures even distribution of spices throughout the batter. Gently fold the flour mixture into the banana purée along with the 1.5 cups packed light brown sugar, 2 whole eggs, 2 teaspoons vanilla extract, and 0.75 cup milk. Mix just until combined—overmixing develops gluten and makes the cake dense.

Divide the batter evenly between the prepared pans. The batter should fill each pan about ¾ full. Tap the pans gently on the counter to remove any air bubbles. Bake for 25-30 minutes until a skewer inserted into the center comes out clean and the tops spring back when touched.

While the cake bakes, it's time for the star of the show—the streusel. In a medium bowl, cut the 1 cup cold unsalted butter into small cubes. Use a pastry cutter or your fingers to work it into the 0.5 cup all-purpose flour until the mixture resembles coarse crumbs with pea-sized butter pieces.

Add the 0.5 cup chopped walnuts and 2 tablespoons icing sugar, then toss everything together with a fork until evenly coated. The walnuts should be fully distributed—this ensures each bite of cake has that perfect crunch. Press half of the streusel mixture firmly over the top of one cake layer while it's still warm. Reserve the remaining streusel for the final assembly.

Let the baked cake layers cool in their pans for 10 minutes, then transfer them to a wire rack to cool completely. Once cool, place one layer on a serving plate and spread a thin layer of banana purée (about 2 tablespoons) over the top. This keeps the layers moist and adds extra banana flavor.

Top with the second cake layer and press the reserved streusel mixture evenly over the top, covering it completely. The streusel should look golden and inviting—this is where the magic happens. Bake the assembled cake at 325°F for 15-20 minutes, until the streusel is deep golden brown and crispy.

Remove the cake from the oven and let it cool for 10 minutes before slicing. The streusel will be soft right after baking but will crisp up as it cools. Serve warm for the best experience—each slice reveals moist banana cake layers with a buttery, nutty crunch on top.

This cake keeps well at room temperature for 2 days, wrapped in cling film. For extra indulgence, dust with extra icing sugar before serving. The combination of warm spices, tender banana cake, and crunchy streusel makes this a showstopper for any occasion!
