Mix all ingredients for dough (except cocoa) - it doesn't matter which order to put the important number. I just stirred with a whisk - it turns a homogeneous mass of the consistency of the liquid smetana.

1/3 pour into another bowl and there are added the cocoa mix.

Grease a pan with vegetable oil (bottom and sides). Need a bowl with high walls - it will be doubled. Saucepan I have the usual 2 l, metal do not contact with the walls of the microwave during cooking (but better, of course, in a special dish!). First pour all of the light dough, then pour in the brown center. After baking, it will be white outside and brown inside, what is particularly interesting for the kiddies)))

Put in the microwave - and voila! I have a microwave Samsung GRILL CE745GR temperature adjustable in degrees and in percentage. I have a 850W power - max. temperature 300 deg. I put 70% in 16 min. (other time and temperature - the effect is) - also important is the voltage - it is individual, maybe You and less time required - it is necessary to try))) Gently take out (I just turn it on a plate) - it turns out to be chubby which is ready for use! but...

I, from excessive amount of free time, cut it into three Korzh and smeared sour cream (1 Cup. sugar + 1 Cup. sour cream - beat until the sugar is dissolved). To decorate - optional))) I have a little yellow marshmallow crumbled. The night was left for impregnation. Ready - what in the photo.
