I've just made low carb carrot cake. It was great to here goes:

60g ground almonds (almond flour)
40g soya isolate powder.
One level teaspoon baking soda.
2 heaped spoons slenda powder
80g grated carrot
1 teaspoon vanilla flavouring (optional)
2 teaspoonfuls rum flavouring (optional)

3 med eggs
30g melted butter
3 dessert spoons cream

Beat the three liquid ingredients together and then blend in the dry stuff. Mix it all very well.

Put into containers and either - nuke for 2 mins or bake for about 5 - 10 mins.

The above made one cake about 4 x 4 to 1.5 inches and 12 little cakes.
