I found small solid boxes for cupcakes

so I tried the following recipe,

They used a white egg

and we can use the yellow

to make a custard cakes to accompany the well:

20 ml milk

150 g brown sugar

50 g of cocoa

75 ge flour

1 teaspoon baking powder

100 g of chocolate

1 egg

three egg whites and 75g sugar

Heat the milk and then add brown sugar

and put on fire to melt.

Then add the chocolate, melt

then cool.

Beat the egg whites with a tablespoon of water,

add half the sugar and beat one minute,

then the remaining sugar and beat another 2 minutes.

Resume the cooled mixture, add one whole egg

then mix flour, cocoa, baking powder.

Then gently stir in the stiffly beaten egg whites.

Put in small boxes,

predict not only fill 2/3

Bake in hot oven about 180 °

without opening and cook for about 20 minutes.

It is best hot with custard very cold, or ice cream!
