Separate the yolk from the protein and add to the bowl with the yolk all the other ingredients ( EXCEPT CHOCOLATE), mix well, I used a mixer.
Now let's get busy with the whites, whisk at high speed of the mixer to strong peaks, it took me about 5 minutes.
Carefully add our proteins to the bowl with the rest of the ingredients, slowly stirring with a spatula, it turns out that this is a lush air mass.
Put a dry frying pan on medium heat and heat it until it is completely hot. Put one tablespoon of dough on the pan, in the middle of our pancakes add one cube of chocolate (for earlier break them into cubes) and cover it with the dough, fry until completely rosy, I got about 2 minutes on each side (it all depends on the pan).
Here are such beauties we have turned out, with this number of ingredients I got 12 pieces, Bon appetit-it's very delicious)))
