Mary Berry Banana Bread — The Classic Recipe
Mary Berry’s banana bread is one of the most searched baking recipes in the United Kingdom. It differs slightly from the American-style banana bread (which often uses bicarbonate of soda as the primary leavener) in that Mary Berry’s version uses self-raising flour, giving a slightly lighter texture. The key to her recipe — as she has noted in interviews and on television — is using very ripe bananas. The riper and darker the bananas, the sweeter and more intensely flavoured the bread will be.
Mary Berry Banana Bread — Ingredients (Serves 8–10)
| Ingredient | Amount |
| Very ripe bananas | 3 large (about 300g peeled weight) |
| Self-raising flour | 225g |
| Caster sugar | 175g |
| Butter, softened | 100g |
| Eggs, beaten | 2 large |
| Baking powder | 1 tsp |
| Milk | 2 tbsp (optional, for looser batter) |
Mary Berry Banana Bread — Method
- Preheat the oven to 180°C/160°C fan/gas 4. Grease and line a 900g (2lb) loaf tin with baking parchment.
- Mash the bananas thoroughly in a large bowl — Mary Berry recommends mashing with a fork until there are very few lumps remaining.
- Add the softened butter, caster sugar, beaten eggs, self-raising flour, and baking powder to the mashed bananas. Beat together until well combined and smooth. If the batter feels too thick, add the milk.
- Pour the batter into the prepared loaf tin and level the surface.
- Bake for 60–70 minutes, or until a skewer inserted into the centre comes out clean. The top should be golden brown and the loaf should have pulled away slightly from the sides of the tin.
- Leave to cool in the tin for 10 minutes, then turn out onto a wire rack to cool completely.
Mary Berry’s Tips for Perfect Banana Bread
- Use bananas that are very ripe — almost black. The natural sugars have concentrated by this point, giving far superior flavour to underripe bananas
- Do not overmix once the flour is added — overmixing develops gluten and makes the bread tough rather than tender
- Check at 55 minutes — ovens vary significantly. If the top is browning too quickly, cover loosely with foil for the remaining cooking time
- The bread keeps well wrapped in clingfilm for 3–4 days, and freezes beautifully for up to 3 months
Mary Berry Banana Loaf Recipe
Mary Berry’s banana loaf and banana bread are closely related — the banana loaf is her name for the same classic recipe in her Complete Cookbook, while the banana bread name is more commonly used in modern searches. Both refer to the same baked loaf. The distinction in Mary Berry’s repertoire is more in presentation: the banana loaf tends to be served sliced plain or lightly buttered, while the banana cake version (see below) is typically iced or layered.
How to Make Mary Berry’s Banana Loaf Extra Moist
- Wrap the cooled loaf tightly in clingfilm and leave for 24 hours before eating — this allows moisture from the banana to redistribute through the crumb, making the texture denser and moister
- Add a tablespoon of soured cream or yoghurt to the batter — this adds moisture without making the bread heavy
- Do not overbake — the loaf is done when a skewer comes out with just a few moist crumbs, not when it comes out bone dry
- Store at room temperature rather than in the fridge — refrigerating banana bread draws out moisture and makes it dry faster
Mary Berry Banana Cake Recipe
The banana cake takes the banana loaf formula and elevates it into a celebration cake — typically baked in two sandwich tins, cooled, and sandwiched with buttercream or cream cheese frosting. Mary Berry has published versions with both buttercream and a banana-flavoured cream cheese filling.
Mary Berry Banana Cake — Ingredients (Serves 10–12)
| Ingredient | Amount |
| Very ripe bananas | 3 large (about 300g peeled weight) |
| Self-raising flour | 225g |
| Caster sugar | 175g |
| Butter, softened | 100g |
| Eggs, beaten | 2 large |
| Baking powder | 1 tsp |
| FOR THE BUTTERCREAM: | — |
| Butter, softened | 100g |
| Icing sugar, sifted | 200g |
| Vanilla extract | ½ tsp |
| Milk | 1–2 tbsp (to loosen) |
Mary Berry Banana Cake — Method
- Preheat oven to 180°C/160°C fan/gas 4. Grease and base-line two 20cm round sandwich tins.
- Make the cake batter as per the banana bread recipe above. Divide evenly between the two tins.
- Bake for 25–30 minutes until golden and springy to the touch. Cool in tins for 5 minutes then turn out onto a wire rack.
- For the buttercream: beat softened butter until pale, then gradually add sifted icing sugar and vanilla extract. Add milk a teaspoon at a time until spreading consistency.
- Sandwich the cooled cakes with buttercream. Dust the top with icing sugar or top with sliced banana and an additional layer of buttercream.
Mary Berry Banana and Walnut Loaf — Moist Banana and Walnut Loaf Recipe
Adding walnuts to the banana loaf is one of Mary Berry’s classic variations — the walnuts provide texture, a slightly bitter contrast to the sweet banana, and a satisfying nutty flavour throughout. Her moist banana and walnut loaf has become one of the most popular variations of her banana baking repertoire.
Banana and Walnut Loaf — Ingredients
| Ingredient | Amount |
| Very ripe bananas | 3 large |
| Self-raising flour | 225g |
| Caster sugar | 175g |
| Butter, softened | 100g |
| Eggs, beaten | 2 large |
| Baking powder | 1 tsp |
| Walnuts, roughly chopped | 75g |
Method: Follow the banana bread recipe exactly, folding in the roughly chopped walnuts after combining the wet and dry ingredients. Reserve a handful of walnut halves to scatter on top before baking — they toast beautifully in the oven and create an attractive finish. Bake at 180°C/160°C fan for 60–70 minutes as for the standard loaf.
Mary Berry Banana Chocolate Loaf
Mary Berry’s banana chocolate loaf combines ripe bananas with melted dark chocolate or chocolate chips for a richer, more indulgent bake. This recipe is popular with children and makes an excellent lunchbox or afternoon tea treat.
Banana Chocolate Loaf — Key Additions
- Add 100g dark chocolate chips (or roughly chopped dark chocolate, 70% cocoa) to the standard banana bread batter, folded in gently after mixing
- For a more intense chocolate flavour: replace 25g of the self-raising flour with 25g cocoa powder — this gives the entire loaf a chocolate colour throughout
- Banana chocolate chip muffins: Use the same batter divided into a 12-hole muffin tin (lined with paper cases) and bake for 18–20 minutes at 180°C/160°C fan — a quick and portable version
Mary Berry Banana Traybake
A banana traybake takes the banana bread batter and bakes it in a rectangular tin, making it easier to cut into squares for larger gatherings or school bake sales. Mary Berry’s traybake approach — bake in a 30cm x 23cm roasting tin for 25–30 minutes at 180°C/160°C fan — gives a thinner, slightly crisper result than the loaf. Once cooled, drizzle with a water icing made from icing sugar and a little lemon juice for a simple but appealing finish.
Mary Berry Carrot and Banana Cake
Mary Berry’s carrot and banana cake combines two of her most popular loaf cake traditions into a single moist, warmly spiced bake. The banana adds sweetness and moisture while the carrot provides texture and a gentle earthiness. The combination works particularly well with a cream cheese frosting. To make it: use 225g self-raising flour, 175g light muscovado sugar, 100ml sunflower oil (instead of butter — keeps it very moist), 2 eggs, 1 tsp mixed spice, 1 tsp cinnamon, 200g grated carrot, and 2 ripe mashed bananas. Bake in a 900g loaf tin at 180°C/160°C fan for 60–70 minutes.

The consistency of Mary Berry’s banana baking also comes from her understanding of how the recipe changes across different pan sizes and ovens. She notes that fan ovens run hotter than conventional ovens — hence the dual temperatures in her recipes (180°C conventional / 160°C fan). For home bakers who are unsure which oven setting they have, the fan setting is now standard on most modern British ovens. Using the wrong temperature is one of the most common causes of banana bread that is golden on the outside but still raw in the centre, or that overcooks on top while remaining underdone through the middle. A properly calibrated oven thermometer (available for around £5–10 from kitchen shops) is a worthwhile investment for any regular baker following Mary Berry’s recipes.
Mary Berry’s Approach to Baking — What Makes Her Recipes Work
Understanding why Mary Berry’s recipes are so consistently successful helps bakers use them more confidently. Her approach rests on a few core principles she has articulated repeatedly through her books and television appearances. First, she always uses good quality ingredients — not necessarily the most expensive, but not the cheapest either. For chocolate, she insists on 70% cocoa dark chocolate. For butter, she uses unsalted. For vanilla, she uses extract not essence. Second, she measures carefully. Unlike some chefs who encourage bakers to ‘trust their instincts,’ Mary Berry’s recipes work because they are carefully calibrated — the ratios of fat to flour to sugar have been tested and refined. Third, she respects the importance of temperature. Softened (not melted) butter for cakes. Cold butter for pastry and crumble. Ingredients at room temperature rather than straight from the fridge, as cold ingredients can cause the batter to curdle. Fourth, she does not overcomplicate. Many of her most popular recipes use a simple all-in-one method — put everything in the bowl and beat together — rather than laborious creaming and folding stages. This approach is reliable and reduces the margin for error. For banana baking specifically, she consistently emphasises one variable above all others: the ripeness of the bananas. A banana bread made with yellow bananas will be noticeably less flavourful than one made with very ripe, dark-spotted bananas. This single ingredient variable has more impact on the final flavour than any technique or additional flavouring. It is why Mary Berry’s instructions always specify ‘very ripe bananas’ — not ripe, not quite ripe, but very ripe. This emphasis on ingredient quality over technique complexity is the hallmark of her approach across her entire baking repertoire.
