Prunes grind in a blender or with a knife. In chopped prunes add soy sauce Kikkoman "Light". Better to do it in advance for a couple of hours before cooking.

Boiled beets grate on a fine grater. Weight grated beet definitely I can not say. I did 4 tablespoons.

In yogurt add vegetable oil, sugar, vanilla sugar, cocoa powder. Stir.

Add beetroot, sifted flour and soda.

Add the prunes. Stir. Pour in the form (22-24 cm) greased with vegetable oil. Bake in a preheated 180 degree oven for 35-40 minutes. I cooked in a slow cooker with a capacity of 800 Watt, in the mode pastries 65 minutes. The cake won't rise and not much increase in volume. It will be very humid, with a texture similar to pudding.

For the glaze mix in a saucepan all ingredients, bring to a boil, stirring constantly. Cover hot cake with icing. Suggest when cooking, do not neglect the glaze, it perfectly complements the taste of the pie.
