For the Cake:
- 250 g self-raising flour
- 2 teaspoons baking powder
- 150 g light muscovado sugar
- 50 g walnut pieces, chopped
- 100 g carrots, coarsely grated
- 2 ripe medium bananas, mashed
- 2 large eggs
- 150 ml sunflower oil
For the Cream Cheese Topping:
- 175 g full-fat cream cheese
- 50 g softened butter
- 100 g icing sugar, sifted
- 1 teaspoon vanilla extract
- Extra walnut halves (for decoration)

How To Make Mary Berry Carrot and Banana Cake Recipe
- Preheat and prep: Preheat your oven to 180 C (160 C fan). Grease a 9-inch (23 cm) round cake tin or a 2 lb loaf tin and line the base with baking parchment.
- The all-in-one method: In a large mixing bowl, combine the flour, baking powder, muscovado sugar, walnut pieces, grated carrots, and mashed bananas. Add the eggs and the sunflower oil.
- Mix until combined: Using an electric hand whisk or a wooden spoon, beat all the ingredients together for about 1 to 2 minutes until the mixture is thoroughly combined. Do not over-beat; you just want a uniform batter.
- Bake to golden: Pour the mixture into the prepared tin and level the surface. Bake for 50 to 60 minutes. You’ll know it’s ready when the cake has risen, is golden brown, and a skewer inserted into the center comes out clean.
- Cool completely: Let the cake sit in the tin for about 10 minutes before turning it out onto a wire rack. It is essential that the cake is completely cold before you attempt to frost it, otherwise the cream cheese will melt.
- Whisk the frosting: To make the topping, beat the cream cheese and softened butter together until smooth. Sift in the icing sugar and add the vanilla extract. Whisk until light and fluffy. Spread generously over the top of the cooled cake and decorate with walnut halves.

Recipe Tips
- Banana Ripeness: The spottier the banana, the better! Overripe bananas have a higher sugar content and a stronger aroma, which provides the best flavor and moisture for the cake.
- Muscovado Sugar: Using light muscovado sugar instead of white sugar is a Mary Berry classic. It gives the cake a lovely caramel-like depth and helps keep the crumb moist.
- Oil vs. Butter: Using sunflower oil instead of butter ensures the cake stays soft and moist for days. It also makes the mixing process much faster.
- Nut Variation: If you aren’t a fan of walnuts, pecans make a wonderful substitute, providing a slightly sweeter, buttery crunch.

FAQs
Can I make this in a loaf tin?
Yes! This recipe works perfectly in a 2 lb loaf tin. The baking time remains roughly the same, but check it at the 50-minute mark.
Why did my cake sink in the middle?
This usually happens if the oven door is opened too early or if too much baking powder was used. Stick to the 2 teaspoons and keep the door shut until at least 45 minutes have passed.
Is the cream cheese topping necessary?
While the cake is delicious plain (like a tea bread), the cream cheese frosting provides the signature u0022carrot cakeu0022 experience and balances the sweetness of the bananas.
