150ml skimmed milk

150ml water

110g whole wheat flour

2 Weetabix biscuits

110g raisins or currants

1 teaspoon ground cinnamon

15g natural sweetener (e.g., stevia or erythritol)

1 large egg, beaten


Begin by preheating your oven to 180°C (160°C for fan ovens) or Gas Mark 4. Prepare a 450g loaf tin by lining it with parchment paper.

In a mixing bowl, break the Weetabix biscuits into small pieces and add the sultanas (raisins or currants). Pour the skimmed milk and water over them, allowing the Weetabix to soak up all the liquid. This will take about 10 minutes.

After the Weetabix has absorbed the liquid, stir in the whole wheat flour, ground cinnamon, and natural sweetener. Mix until all the ingredients are well combined.

Add the beaten egg to the mixture, stirring it in thoroughly. The batter should have a smooth and consistent texture.

Carefully transfer the cake mixture into the prepared loaf tin, spreading it evenly.

Place the tin in the preheated oven and bake for approximately 1 hour and 15 minutes, or until the cake is cooked through. To check if it’s done, insert a toothpick or skewer into the centre; it should come out clean when the cake is ready.

Once baked, remove the cake from the oven and allow it to cool in the tin for a few minutes. Then, transfer it to a wire rack to cool completely.

Once the cake has cooled, slice it into 12 equally-sized portions. Serve and enjoy your guilt-free Weetabix Fruit Cake as a delicious snack or dessert. Each slice is a delightful balance of sweetness and healthiness, making it the perfect treat for any occasion.
