Hi
Fruit sugar I avoid, but use Splenda in baking
Basic cakes/biscuits can be made by using ground almonds, add eggs, vanilla essence, baking powder splenda. I often add cinammon or dark choc (small amounts) and they dont do much to blood sugar.
100g ground almonds/1 egg/ tsp vanilla, half tsp baking powder as basic. Rest you can experiment with .Or if you want more, maybe up the amounts
Low carb websites have good recipes and I posted a choc brownie one on here (i think). Sometimes you need soya protein isolate or whey flour but easy to get online or at some health shops ( tend to be more expensive)
