Add egg and vanilla to the butter mixture. Mix well.
Pour in the milk.
Pour in the flour + cocoa and gently, with a spoon, knead the soft dough.
Cover the baking sheet with baking paper. Spread the dough with a tablespoon "slide". There should be enough space between them for further "growth"))) The oven should be preheated to 200C. Send cookies to it for 15 minutes so that it increases in size.
Cut marshmallows into pieces lengthwise and across, as the hungry soul wishes)) Spread one piece of marshmallow on each cookie, lightly pressing the marshmallow to the liver.
Return to the oven for 3-5 minutes.
