Raspberry and Lemon Sponge Cake


Slimming Eats Raspberry and Lemon Sponge - vegetarian, Slimming World and Weight Watchers friendly

Today I was craving some cake, so I decided to see if I could make a sponge cake low in syns. This was delicious served with a nice cup of tea. I am not normally a fan of artificial sweeteners, but for this recipe I don’t find you get that horrid taste, sweeteners sometimes have.

  • Wendy

    I’m drooling looking at that cake. I think I know where my syns will go today x

  • Amanda

    I am in need of something cake-ey so thought I’d browse your recipes, this looks terrific.

    Is it possible to use extra Splenda, rather than the 5 teaspoons of real sugar?


  • What can I use as a substitute for quark in this recipe? I’m in the U.S. and the only kind of quark I’ve seen isn’t the fat free kind. Thanks

  • Chloe

    I made this cake following the recipe and when it was cooked, it literally looked like 2 flat pancakes? I honestly do not believe that cake photograph is for this recipe.

    I can assure you that this is a geniune photo to my recipe. I am not sure why yours didn’t turn out the same. Did you use plain flour instead of self raising or open the oven when it was still cooking, as either of those things could prevent the cake from rising, other than that I can’t say why it went wrong for you, I have had many emails from readers who loved this recipe.
