Beat eggs with salt and sugar. Then pour a glass of milk into the mixture and beat again. Pour flour, beat so that there are no lumps left. Continuing to beat, gradually pour the remaining milk into the dough. You should have a fairly liquid dough.
Now you can bake pancakes. The dough should be in different colors. Therefore, pour a third of the test into a separate container - this is to create patterns for future pancakes. In the rest, add cocoa and mix very well to make the dough uniform, without lumps.
Heat the pan well, pour in a little oil, evenly distribute in the pan and heat. Pour in a little dough, literally ½ a scoop and distribute throughout the pan. A little bake.
Use a teaspoon to draw a little dough and draw arbitrary patterns on pancakes. Then turn the pancake and fry on the other side.
Remove from heat, roll them upside down with patterns.
