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.
100g soft butter, at room temperature
175g light brown sugar
2 large eggs
2–3 ripe bananas, mashed (about 225g)
225g self-raising flour

50g walnuts, roughly chopped
1 teaspoon vanilla extract
Pinch of salt
Optional: ½ teaspoon ground cinnamon

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