Beat eggs with sugar, add the yogurt, the oil and flour sifted with baking powder and vanilla. Do not worry that the dough is very thick so it should be. Bake the cake dough until ready to 180C degrees. After baking leave the cake to cool completely. In principle, the cake should stand for one day, but I prepare once it has cooled down completely. For glaze put the milk in a pan to heat on the stove, boils, add the butter, sugar to melt and then quilt. Stir well to melt couverture and retract slightly cool. Cut the cake as you like triangles or squares. I cut into triangles, roll each piece into a glaze and then in coconut. Cupcakes leave soaking for several hours.
