Banana Walnut Muffins
Tall, domed tops, soft spiced crumb, plenty of walnuts. A reliable way to use up over-ripe bananas.

Bananas have a way of ripening all at once, going from firm to freckled to fully black in what feels like a single day. These muffins exist for exactly that moment, turning a counter of overripe fruit into something worth baking.
The trick to bakery-style domed tops is a hot start: bake the first five minutes at a high heat to spring the muffins up, then drop the temperature so they finish through without burning.
Ingredients
- 3 very ripe bananas (about 300g peeled), mashed
- 115g (½ cup) unsalted butter, melted
- 150g (¾ cup) light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 120ml (½ cup) sour cream or Greek yoghurt
- 260g (2 cups) all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- 1 teaspoon cinnamon
- ½ teaspoon salt
- 100g (1 cup) walnuts, roughly chopped
Instructions
- Heat the oven to 220°C (425°F) and line a 12-cup muffin tin.
- In a large bowl, whisk the mashed bananas with the melted butter, brown sugar, eggs, vanilla and sour cream.
- In another bowl, whisk the flour, baking soda, baking powder, cinnamon and salt.
- Fold the dry ingredients into the wet just until you no longer see flour. Fold in the walnuts, keeping a small handful back for the tops.
- Divide the batter between the muffin cups, filling each almost to the top. Scatter the reserved walnuts over.
- Bake at 220°C for 5 minutes, then drop the heat to 180°C (350°F) without opening the oven and bake for 16–18 minutes more, until a skewer comes out clean.
- Cool in the tin for 5 minutes, then lift onto a rack.
Cooking tips
- The browner and softer your bananas, the better the muffins. Black-spotted is ideal.
- Don't overmix the batter — a few streaks of flour are fine. Tough muffins are usually over-stirred.
- Wrapped tightly, these freeze brilliantly. Defrost overnight or warm in a low oven.
