    Cake Instructions

    • Cream the butter and the Erythritol until light and fluffy. Add the eggs one at a time, beating well to blend incorporate before adding next egg.
    • Mix the remaining dry ingredients and stir ensuring the baking powder is well distributed.

    Glaze method

    • Combine lemon juice and sweetener together. Drizzle over the top of the cake.


    Using Sweeteners
    I minimize the amount of sweetener used in recipes to reduce my sweet tooth, so you may wish to increase the amount to your taste. Taste the batter after you have mixed it and it will give you an idea of whether it will be sweet enough for you. If you switch sweeteners and use a Stevia or Monkfruit and Erythritol blend, it is a lot sweeter than Erythritol or Xylitol on it's own, so you will need to reduce the amount that you use, ie I would recommend 1-2 tablespoons. If you don't have confectioners sweetener, simply blitz some erythritol or erythritol blends in a food processor till fine.
