Step 1: Preheat the Oven
Preheat your oven to 180°C conventional / 160°C fan / Gas Mark 4.
Lightly grease and line a small 450g (1lb) loaf tin with non-stick baking parchment.
Step 2: Soften the Weetabix
Place the Weetabix biscuits in a large mixing bowl and crush them into small pieces.
Pour over the skimmed milk and leave for approximately 2–3 minutes.
Once softened, mash everything together with a fork until you have a thick mixture.
Step 3: Add the Remaining Ingredients
Add the raisins, self-raising flour, mixed spice and granulated sweetener.
Pour in the beaten eggs and add the grated carrot if using.
Mix gently until all the ingredients are evenly combined.
Avoid overmixing, as this can make the finished cake heavier.
Step 4: Transfer to the Loaf Tin
Spoon the mixture into your prepared loaf tin.
Spread it evenly and smooth the top using the back of a spoon.
Step 5: Bake Until Golden
Place the tin in the centre of the preheated oven.
Bake for approximately 45–60 minutes, checking towards the earlier end of the range.
The cake should be golden brown, firm to the touch and cooked through in the centre.
Insert a skewer into the middle of the loaf. If it comes out clean, without wet batter, the cake is ready.
If the top begins browning too quickly, loosely cover it with foil.
Step 6: Cool and Slice
Allow the cake to cool in the tin for approximately 10 minutes.
Carefully transfer it to a wire rack and leave to cool completely.
Slice into 12 portions and enjoy!
How to Make Weetabix Cake in the Air Fryer
Prefer using your air fryer? You can prepare the same delicious Weetabix fruit loaf with a few adjustments.
Air Fryer Instructions
- Preheat your air fryer to 160°C, if your model requires preheating.
- Prepare the Weetabix mixture using the same method described above.
- Lightly grease and line a small air fryer-safe loaf tin that fits comfortably inside the basket.
- Spoon the mixture into the tin and smooth the surface.
- Air fry for approximately 30–40 minutes, checking regularly from 25 minutes onwards.
- If the top browns too quickly, loosely cover the loaf with foil only if your air fryer manufacturer permits it, ensuring the foil is secure.
- Check the centre with a skewer. Continue cooking in short intervals if any wet batter remains.
- Allow the loaf to cool before slicing into 12 portions.
Important: Air fryer temperatures and cooking times vary between models. A lower temperature than a conventional oven often helps prevent the outside from browning before the centre is cooked.
Tips for the Best Weetabix Fruit Loaf
Allow the Weetabix to Soften
Letting the biscuits absorb the milk before adding the other ingredients helps create a more even cake mixture.
Do Not Overmix
Stir the ingredients just until combined. Overmixing can affect the finished texture.
Use Fresh Self-Raising Flour
Check that your flour is within its best-before date and has been stored correctly for reliable results.
Choose the Right Loaf Tin
A small loaf tin works best for this quantity of batter. Using a much larger tin may produce a flatter cake that cooks more quickly.
Keep an Eye on the Baking Time
Every oven and air fryer behaves differently. Start checking before the maximum recommended cooking time to avoid drying out the loaf.
Let the Cake Cool Before Slicing
The loaf will be easier to cut once it has cooled and the crumb has had time to set.
Easy Weetabix Cake Variations
One of the best things about this recipe is how easy it is to customise.
Apple and Cinnamon Weetabix Cake
Replace some of the raisins with finely diced apple and add a little ground cinnamon.
Orange and Raisin Weetabix Cake
Add finely grated orange zest for a lovely citrus flavour that pairs beautifully with the raisins.
Carrot and Spice Weetabix Loaf
Include the optional grated carrot and add a small pinch of ground ginger for extra warmth.
Sultana Weetabix Cake
Swap the raisins for sultanas to create a slightly different fruity flavour.
Nutty Fruit Loaf
Add a small handful of chopped walnuts for extra crunch. Remember that additional ingredients may change the cooking time.
Is Weetabix Cake a Healthy Option?
This Weetabix cake can be enjoyed as part of a varied, balanced diet.
Weetabix and wholegrain wheat provide some fibre, while raisins contribute natural sweetness and fruit flavour.
Using skimmed milk and a baking sweetener can also change the recipe’s nutritional profile compared with some traditional fruit cakes.
However, the cake still contains carbohydrates and naturally occurring sugars from ingredients such as raisins and milk.
The nutritional value will depend on your exact ingredients, portion sizes and any substitutions you make.
For a balanced approach, enjoy a slice as part of your usual meals and snacks.
How to Store Weetabix Cake

Once completely cooled, store the cake in an airtight container in a cool, dry place.

In the Fridge
Store the cooled loaf in an airtight container in the refrigerator for up to 3–4 days.

Can You Freeze Weetabix Cake?
Yes!

Wrap the slices well and place them in a freezer-safe container or bag.
Freeze for up to 2 months for best quality.
