Products must be room temperature. Preheat the oven to 180 degrees. Meanwhile, the egg+sugar+vanilla sugar= mix with a mixer for 5 minutes.

Melt the butter and cool, but not frozen. Milk slightly warmed. In the egg-sugar mixture pour in the butter and milk (milk should not be cold, otherwise the butter will be melted flakes ) Mix.

Frozen berries roll them in starch to be evenly distributed in the cupcake baking time

Mix flour+salt+baking powder, sift into the egg-sugar-milk mixture, gradually stirring until the dough. When all the flour pour, stir thoroughly, so that lumps were the least desirable. Pour in the dough berries in starch. Mix well distributing the berries on top. Spread in a greased form (here I screwed up... I had a form to take a bigger, preferably of the type 30 cm to 11 cm, in General, what would the dough a thick layer lying in it)

Bake for about 30 minutes under foil. Then remove foil and bake Golden brown and dry toothpick Cupcake... be sure to cool in the form and then it is removed, otherwise it will fall apart. Here it is, with a ruddy crust cools

Cut the cooled cake into slices and drink tea... coffee... iSEVEN in General treat as you can)))
