Mary Berry Banana and Walnut Loaf

Mary Berry Banana and Walnut Loaf recipe

Mary Berry Banana and Walnut Loaf is a classic British loaf cake made by folding mashed bananas into a buttery batter, then adding chopped walnuts for texture. The bananas keep the crumb tender and lightly sweet, while the nuts add contrast. Baked slowly in a loaf tin, it slices neatly and keeps well for several days.

Ingredients

  • 100g soft butter, at room temperature

  • 175g light brown sugar

  • 2 large eggs

  • 2–3 ripe bananas, mashed (about 225g)

  • 225g self-raising flour

  • ½ teaspoon baking powder

  • 50g walnuts, roughly chopped

  • 1 teaspoon vanilla extract

  • Pinch of salt

  • Optional: ½ teaspoon ground cinnamon

Instructions

  • Prepare the tin – Line a loaf tin with baking parchment and preheat the oven to 170°C (340°F).

  • Cream butter and sugar – Beat together until pale and fluffy.

  • Add eggs – Beat in the eggs one at a time, mixing well after each.

  • Mix in bananas – Stir in the mashed bananas and vanilla extract.

  • Combine dry ingredients – Sift flour, baking powder, salt, and cinnamon together.

  • Fold gently – Fold the dry ingredients into the batter until just combined.

  • Add walnuts – Stir in the chopped walnuts evenly.

  • Fill the tin – Spoon the mixture into the prepared tin and level the top.

  • Bake steadily – Bake for 50–60 minutes until golden and a skewer comes out clean.
