Instructions

  1. Preheat the oven to 300 degrees F/150 degrees C. To make the bread 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 bread batter in the fridge while making the streusel.
  2. To make the crumb topping in a separate bowl, mix all-purpose flour (5 tbsp/40 g) and almond flour. Add icing (powdered) sugar and chilled 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 batter into the pan, sprinkle the streusel on top, and bake for 90 minutes. The bread is ready when a toothpick inserted into the center of the cake comes out clean. Sprinkle the top of the bread with flaked toasted almonds and dust with icing (powdered) sugar.

Notes

  1. Soften unsalted 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. Mash bananas with a fork, an electric handheld mixer, or a potato masher.
  4. Do not overmix the bread batter when you add crushed bananas. Instead, gently mix to combine.
  5. Split the recipe into four small loaves or make banana bread mini muffins if you prefer.
  6. Adjust your oven's baking time: I have tested and re-tested 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.
