Slimming World Diet Coke Chocolate Cake (Low Syn)

Now for as long as I can remember, I have always been a fan of Coca-Cola, but I never knew that you can cook with it and make some amazing recipes, this Slimming World Diet Coke Chocolate Cake (Low Syn) is just one of the amazing recipes I have.

Now if you think this cake is going to kill your healthy eating, then no, not at all. I have managed to make some tweeks, so now the recipe is coming in at 4 syns per slice.


As this Slimming World Diet Coke Chocolate Cake would work for a celebration, it can be made for any occasion. One thing I am sure is that people won’t know it is a healthy cake.


I am sure you have seen recipes all over the internet for low syn cakes, the will use scan bran or something else like that. Well that is not cake. This is seriously the best cake that I have ever made on Slimming World and at only 4 syns, you can afford to have a treat and know that you are still on point.


Alternatively, if you are wanting a recipe for cupcakes, follow this recipe and put it into cupcake cases instead. It should made around 16 cupcakes, that would make 3 syns per cupcake.

    I made this cake today. I haven’t tasted it yet but I feel that there is a lot of sweetner used. Now that sweetner is syned, is this cake still 4 syns per slice ?

    • Hello, as working out the syns based upon the new syns that Slimming World have given the cake, it now works out to be 4.5 syns per slice. Hope this clarifies everything.
