How To Make Mary Berry Carrot and Walnut Cake
- Prepare the cake tin: Preheat the oven to 180°C (350°F). Grease an 8-inch round cake tin and line the base with parchment paper.
- Make the batter: In a large bowl, add all the cake ingredients—flour, baking powder, salt, sugar, walnuts, grated carrots, mashed bananas, eggs, and oil. Beat everything together until the mixture is smooth and well combined.
- Bake the cake: Pour the batter into the prepared tin and level the surface. Bake for 50–60 minutes, or until the cake is well-risen and slightly pulling away from the sides. Let it cool in the tin for a few minutes before turning it out onto a wire rack. Peel off the parchment paper and leave to cool completely.
- Make the frosting: In a bowl or food processor, beat the cream cheese, butter, confectioners’ sugar, and vanilla extract until smooth and creamy.
- Decorate the cake: Spread the frosting evenly over the cooled cake, using a spatula to create a decorative swirl. Top with walnut halves and chill for a short time before serving.

Recipe Tips
- Extra flavour: Add a teaspoon of cinnamon or nutmeg to the cake batter for extra warmth.
- Mashed bananas: The riper the bananas, the better—they add natural sweetness and moisture.
- Chilling the frosting: If the frosting is too soft, chill it for 10–15 minutes before spreading.
How To Store This Carrot and Walnut Cake
Storing in the Fridge: Because of the cream cheese topping, store the cake in an airtight container in the fridge for up to 4 days. Bring to room temperature before serving.
Freezing: The unfrosted cake can be wrapped in cling film and frozen for up to 3 months. Thaw at room temperature before adding the frosting.
