Hello!
How about a Marzipan cake for Rosh Hashanah?
My sister, Shoshi, made a wonderful L/C cake. Give it a try:
7 eggs
5 tablespoons of “nitzat HaDuvdevan” soy flour (38 carbs for 100 gr. 5 spoons is about 50 gr = 19 carbs)
1 teaspoon vanilla
¼ cup oil
15 ml liquid diatip by sucrazit
1 tablespoon almond flavor

separate the eggs
whip the egg whites till stiff and add sweetener
continue whipping and fold in the egg yokes and everything else.
Put in oven 175C for 30-45 min

You can use 2 spoons of coco powder or coffee instead of the almond.

Shana Tova!
