Preheat oven at 350°F.

Stif together the flour, cocoa powder, sugar, salt, baking powder and baking soda.

In a different bowl add the milk and white vinegar. Let it stand for a couple of minutes. Then add the egg yolks, vanilla, oil and coffee. Mix them well together.

Pour the milk mixture to the flours and mix them well.

Beat the egg whites separately, until you have a white foam. Incorporate it to the batter very slowly, without over beating.

Put the batter in two 8" molds, greased.

Bake them for 25-30 minutes, or until the toothpick comes out clean.

For the fudge put all the ingredients, except the butter in a cooking pan, over medium heat. Move it constantly until you have the desire texture. When ready put a teaspoon of butter to give it that shine.

When the cake is ready let it cool for about 5 min in the mold and then in the rack. Put 1 of the cakes as a base and top it with the fudge. Then put the other cake on top of it and cover completely with fudge.

Enjoy this delicious recipe.
