Put flour, baking powder, salt and sugar in a bowl. Stir in eggs, 1/8 l water and milk. Cover the dough and let it swell for about 20 minutes
Heat 1/2 teaspoon fat in a small coated pan. Bake 1/8 of the dough in it at medium heat for 2-3 minutes until golden brown. Sprinkle with some sesame seeds, turn and bake from the second side. Keep warm
Bake 7 more crêpes from the remaining dough little by little
Arrange 2 crêpes on dessert plates. Use the ice-cream scoop or a tablespoon to cut 4 scoops or cams from the ice cream. Arrange on the crêpes and pour some chocolate sauce over each one. Decorate with mint. Serve immediately
