Mary Berry’s carrot cake traybake is a light, moist sponge cake baked in a rectangular tin and topped with creamy frosting. Unlike traditional layered carrot cakes, the traybake version is straightforward to prepare and slice, making it ideal for picnics, potlucks, or school lunches. The grated carrots add natural sweetness and moisture, while the cinnamon and walnuts (optional) give it depth and texture.
For the cake:
Self-raising flour – 225g
Baking powder – 1 tsp
Light brown sugar – 175g
Ground cinnamon – 1 tsp
Grated carrots – 150g (about 2 medium carrots)
Chopped walnuts – 50g (optional)
Eggs – 2 large
Sunflower oil – 150ml
Crushed pineapple (drained) – 50g (adds moisture)
For the frosting:
Full-fat cream cheese – 150g
Soft butter – 50g
Icing sugar – 100g
Vanilla extract – ½ tsp
Preheat the oven to 180°C (160°C fan) / 350°F. Grease and line your baking tray with parchment paper, ensuring it fits neatly along the edges.
In a large bowl, combine self-raising flour, baking powder, cinnamon, and brown sugar. Mix gently to remove any lumps.
Add eggs, oil, and crushed pineapple to the dry mixture. Beat together using an electric whisk until well combined and smooth.
Stir in the grated carrots and walnuts (if using) using a spatula. Mix until evenly distributed throughout the batter.
Pour the mixture into the lined tray and spread evenly. Bake for 35–40 minutes, or until the cake is golden and springs back when lightly pressed in the center.
Let the cake cool in the tin for 10 minutes, then transfer to a wire rack to cool fully before icing.
Beat butter until smooth. Add cream cheese, vanilla, and icing sugar and continue to beat until light and fluffy. Refrigerate for 10 minutes to firm up slightly before spreading.
Spread the icing evenly over the cooled cake. Optionally, sprinkle chopped walnuts or a light dusting of cinnamon on top for decoration. Slice into squares to serve.
