Ingredient Notes

Weetabix: These wholegrain wheat biscuits form the base of the cake and help give it a hearty texture.

Skimmed milk: Softens the Weetabix and helps combine the ingredients into a thick cake mixture.

Raisins: Add fruity sweetness and a lovely chewy texture. You can also use sultanas if preferred.

Self-raising flour: Helps the loaf rise and creates a softer crumb.

Mixed spice: A classic British baking spice blend that complements the raisins beautifully.

Granulated sweetener: Choose a product designed for baking and follow its sweetness-equivalence guidance, as different brands vary.

Eggs: Help bind the ingredients together and give the loaf structure.

Carrot: Optional, but adds moisture and a subtle sweetness. Grate it finely so it blends easily into the cake.
