Low Syn Victoria Sponge Mug Cake

Creating a low-syn Victoria Sponge Mug Cake for a Slimming World diet can be a delicious and satisfying treat. Here’s a simple recipe for you:


For the cake:

  • 4 tablespoons self-raising flour
  • 2 tablespoons sweetener (adjust to taste)
  • 1 large egg
  • 2 tablespoons fat-free Greek yogurt
  • 1/2 teaspoon vanilla extract

For the filling:

  • Fresh strawberries or raspberry jam (choose a low-sugar or sugar-free option)


  1. In a microwave-safe mug, whisk together the self-raising flour and sweetener.
  2. Add the egg, fat-free Greek yogurt, and vanilla extract to the mug. Mix well until you have a smooth batter.
  3. Microwave the mug on high for 1.5 to 2 minutes. The cooking time may vary depending on your microwave, so keep an eye on it. The cake should rise and become firm to the touch.
  4. Let the mug cake cool for a few minutes.
  5. Once the cake is cool, carefully slice it in half horizontally, creating two layers.
  6. Spread a layer of fresh strawberries or a thin layer of low-sugar or sugar-free raspberry jam on one half of the cake.
  7. Place the other half of the cake on top to create a sandwich effect.
  8. Optionally, dust the top with a little extra sweetener or powdered sugar substitute.
