Sugar free butter cream

This is my standard butter cream recipe that I now use. Based on a german butter cream, a thick 'custard' is made first, which needs to be chilled before whisking in the butter. Occasionally, t can be a bit tricky to get the temperature right. You are basically making an emulsion of fat and liquid, so if the custard is too warm, or the butter too cold they will not blend well and the butter cream will separate (curdle). Likewise, if it is too cold, the butter will harden and you will see flecks of butter in the mixture. Both problems are easily remedied by standing the butter cream above a bowl of hot water, or standing it in a bowl of cold water depending on which problem you have encountered. It is less cloying than the usual 'butter and icing sugar' blend, with a creamy texture, so persevere. It is worth it!


1tbsp cornflour
1/2c milk (or use 1/4c coconut milk and 1/4 c rice milk if you are dairy free)
125g butter, softened
1/3c xylitol or 1/8-1/4tsp stevia powder
2tsp vanilla extract

Blend the cornflour and milk together. Heat in a pan, stirring continuously, until thick.
Spoon into a bowl, cool to room temperature then refrigerate.

Once the thickened milk is completely cold, whisk in the xylitol and vanilla extract. (An electric stick blender is handy for this) gradually add the softened butter until it is smooth and slightly fluffy.

The butter cream can be flavoured with 2-3 tbsp of fruit puree, or the vanilla can be omitted and 1-2tbsp of cocoa powder blended into the cornflour before the milk is added.
