Treat yourself to a slice of the best streusel-topped banana bread. It is made with brown sugar and lots of bananas, flavored with dark rum, and baked with a delicious crunchy streusel (crumb) topping. When you think that you have tried all the banana bread recipes, there is the only one left to try!



For the cake batter:

  • 5.3 oz. (150 g) butter softened
  • 1 cup (200 g) brown sugar
  • 2 eggs
  • 1 2/3 cup + 4 tablespoons (240 g) all-purpose flour

  • 1 fl. oz. (30 ml) dark rum

  1. Preheat the oven to 300 F/150 C. To make the cake batter, beat softened butter and brown sugar for 5 minutes, using an electric mixer. Add all-purpose flour (1 2/3 cup + 4 tablespoons/240 g) mixed with baking powder, eggs, and delicately mix with a rubber spatula. Mash bananas with a fork and fold them into the principal preparation. Add rum and mix with a spatula just until combined. Place the cake batter in the fridge while making the streusel.
  2. To make the streusel topping in a separate bowl, mix all-purpose flour (5 tbsp/40 g) and almond flour. Add icing (powdered) sugar and chilled semi-salted (or salted) butter cut into pieces and make the crumbly dough with your hands. It has to look like wet sand.

  3. Butter and flour a silicone loaf pan or line a nonstick loaf pan with parchment paper. Pour the cake batter into the pan, sprinkle the streusel on top, and bake for 90 minutes. The cake is ready when a toothpick inserted into the center of the cake comes out clean.

  4. Sprinkle top of the cake with flaked toasted almonds and dust with icing (powdered) sugar.


  1. Soften unslated butter by taking it out of the fridge 2 hours before cooking.
  2. Replace dark rum with some juice if you serve the cake to kids.
  3. Crush bananas with a fork, an electric handheld mixer, or a potato masher.
  4. Do not over-mix the cake batter when you add crushed bananas. Gently mix just to combine.
  5. Split the recipe into two smaller loaves or make banana muffins if you prefer.
  6. Adjust your oven's baking time: it has been tested and re-tested by me that the cake is ready in 90 minutes.
  7. Test the cake for readiness! Use a toothpick: if it is inserted in the middle of the cake, comes out clean, the bread is ready. If it still has the batter on it, add another 3 to 5 minutes and test again.
  8. Cool the baked banana bread completely before slicing.
  9. Serve with a dollop of mascarpone or slabs of salted butter.
