For years, people following the Slimming World plan have used clever swaps to recreate their favourite comfort foods. Cereal is not just for breakfast anymore. By using a classic breakfast staple, you can create a moist cake.
This suitable for Slimming World Weetabix cake recipe is perfect for anyone looking to eat healthier without feeling deprived. It uses simple ingredients that you probably already have in your kitchen cupboards. Best of all, it is easy to make, even if you are not an expert baker.

What Makes Weetabix Cake So Brilliant?
When you first hear about making a cake out of breakfast biscuits, you might be a little bit sceptical. It sounds strange to turn a bowl of cereal into a cake. However, the texture of Weetabix mimics flour and oats well when mixed with wet ingredients.
The main reason this cake is so popular is the high fibre content. Weetabix is packed with whole wheat, which helps keep your digestive system well and leaves you feeling fuller for longer. When you are trying to lose weight, finding snacks that actually fill you up is essential. The NHS Eatwell Guide recommends eating plenty of higher fibre foods, and this suitable for Slimming World Weetabix Cake is a good way to boost your daily intake.
Another great benefit is the low-fat content. Traditional cakes use large amounts of butter and oil to keep the sponge moist. This suitable for Slimming World Weetabix Cake recipe relies on milk, eggs, and fruit to provide moisture without adding unnecessary calories. You end up with a dense, fruity loaf that tastes quite similar to a traditional bread-and-butter pudding or a malt loaf.
The Suitable for Slimming World Weetabix Cake Recipe
This classic version is naturally sweet and packed with plump fruit.
Ingredients You Will Need
To make this simple bake, gather the following ingredients:
- 2 Weetabix biscuits
- 100g sultanas or mixed dried fruit
- 150ml skimmed milk
- 150ml water
- 100g self-raising flour
- 1 teaspoon of mixed spice
- 2 tablespoons of granulated sweetener (make sure it is suitable for baking)
- 2 large eggs, lightly beaten
Step-by-Step Instructions
- Start by placing your two Weetabix biscuits into a large mixing bowl. Pour the skimmed milk and water over the top. Use a fork to crush the biscuits and stir the mixture until it looks like a thick porridge.
- Stir your sultanas into the wet mixture. Leave this bowl to soak for at least 30 minutes. Some people even like to leave it soaking overnight in the fridge to make the fruit extra plump.
- Preheat your oven to 180 degrees Celsius (or 160 degrees Celsius for fan ovens). Line a 1lb loaf tin with non-stick baking paper.
- Once the mixture has soaked, add the self-raising flour, mixed spice, sweetener, and beaten eggs to the bowl. Stir everything together gently until all the ingredients are fully combined. Be careful not to overmix, as this can make the cake tough.
- Pour the cake batter into your lined loaf tin. Smooth the top with the back of a spoon.
- Bake in the centre of the oven for about 45 to 50 minutes. You can check if it is ready by inserting a skewer into the middle. If it comes out clean, the cake is done.
- Leave the cake to cool in the tin for 10 minutes, then transfer it to a wire rack to cool completely.
Alternative flavours for your suitable for Slimming World Weetabix Cake
Once you have mastered the basic recipe, you can adapt it easily. Here are a few brilliant variations to try.
Chocolate Orange Delight
If you are a chocolate lover, swap the mixed spice for one tablespoon of cocoa powder. Instead of sultanas, use the zest of one whole orange and a small handful of dark chocolate chips. The cocoa adds a rich flavour, while the orange zest keeps it tasting fresh and bright.
Apple and Cinnamon
This version tastes just like autumn. Peel and finely dice one medium dessert apple. Swap the sultanas for the diced apple and use ground cinnamon instead of mixed spice. The apple releases extra moisture as it bakes, making the cake really soft. This also smells amazing while it is cooking in the oven.
Lemon and Blueberry
For a lighter, summery twist, use the zest of a lemon and a handful of fresh or frozen blueberries instead of dried fruit. The blueberries burst during baking, creating lovely little pockets of fruity juice throughout the sponge. This version pairs well with a spoonful of fat-free plain Greek yoghurt on the side.
How to Fit This Treat Into Your Slimming World Plan
Understanding how to track your food is crucial when following the Slimming World plan. The beauty of this suitable for Slimming World Weetabix Cake is that it uses ingredients that fit perfectly into your daily allowances.
The Weetabix can count towards your Healthy Extra B allowance, as it is a great source of fibre. The skimmed milk can be measured and taken from your Healthy Extra A allowance. This means the only ingredients you really need to count are the flour and the dried fruit.

Baking and Storage Tips for the Best Results
Baking healthy cakes can sometimes be tricky because the lack of fat means they can dry out faster than regular cakes. Luckily, there are a few simple tricks to keep your Weetabix cake tasting fresh.
Because this cake contains quite a bit of moisture from the soaked cereal and fruit, it is best stored in an airtight container in the fridge. It will happily keep for up to four days. In fact, the texture improves on the second day, becoming slightly stickier and denser.
This cake also freezes well. Once it is completely cool, slice the cake into individual portions. Wrap each slice tightly in cling film and place them all in a freezer bag. This is a great way to control your portions. You can just grab one slice out of the freezer and let it defrost at room temperature for a couple of hours. Having a healthier snack ready to go stops you from reaching for the biscuit tin.

Suitable for Slimming World Weetabix Cake Frequently Asked Questions (FAQ)
Can I use flavoured Weetabix for this recipe?
Yes, you certainly can. Chocolate Weetabix or banana flavoured Weetabix work really well and add an extra layer of flavour. Just remember to check the nutritional values, as flavoured versions often contain more sugar and may have a higher swip value on Slimming World.
Can I make this cake in the microwave?
While the oven gives the best traditional cake texture, you can cook this in the microwave if you are short on time. Pour the mixture into a microwave-safe silicone dish and cook on high for about 8 to 10 minutes. Keep an eye on it, as microwaves vary in power. It will be slightly softer and more pudding-like, but still totally delicious.
Is it possible to make this recipe gluten free?
Yes, this is very easy to adapt. Simply swap the regular Weetabix for a gluten-free cereal alternative and use a gluten-free self-raising flour blend. You might need to add an extra splash of milk, as gluten-free flour tends to absorb more liquid.
Can I use a different cereal instead of Weetabix?
Oat bix, supermarket own-brand wheat biscuits, or even plain porridge oats work as a substitute. If you use oats, you will end up with something closer to baked oats than a traditional loaf cake, but it will still taste lovely.
