In the bowl of the mixer add the eggs, the ointment point butter, the xylitol, and beat until homogenized, add the milk, flour, salt and cocoa powder mix again until homogenized.
Then, add the yeast and mix without beating. Bake in a preheated oven at 180°C until golden.
In a pan, place the cream, still with the whey, the cocoa powder and the xylitol, mix and put it on the fire, still stirring, until you get a brigadeiro, taking off from the pan, but still soft.
Unmold and cover the cake with the brigadeiro, serve warm or cold.
