How to make
Beat the eggs with the butter until creamy and gradually add the sugar. Beat until dissolved and add the cocoa, milk, oil, flour sifted with baking soda or baking powder and finally - the vanilla.
Beat everything to mix the ingredients. Pour the mixture into heart-shaped cake forms, and if necessary, butter and flour them. Bake in a preheated 340°F (170 °C) oven for about 15-20 minutes (or more, depending on your oven).
The important thing is for the baked hearts to remain moist, not dry. Let the hearts cool and remove them from the forms. Prepare a topping by melting the crushed chocolate in milk and adding the butter and cocoa.
Pour this chocolate sauce over the hearts and leave them for 1-2 hours in the refrigerator.
