  • Bold cocoa richness

    I’ve been searching for a really good sugar-free cake for a long time, and I’m so happy I found Yumbles!

    Sugar Free Chocolate Cake with Xylitol

    Disappointed with the quality. The cake was very dry and tasted strongly of bicarbonate of soda. The icing was nice though. For the price I did not feel it was value for money.

    Gluten Free Chocolate Chip Cake

    The cake was delicious and has stayed beautifully moist stored in the fridge for almost a week! It was a perfect plain base to be decorated for my daughters christening, I loved that she was able to enjoy her own cake with no risk of an allergy flare up and we didn’t have to compromise on taste, will definitely be repurchasing for other celebrations!

    Egg & Dairy Free Vanilla Cake
