Cut the ham and cheese into small cubes.
Whisk butter and sugar at room temperature, and pour milk, continue to whisk.
Then add the flour, eggs and baking powder and knead the dough. It should come out a bit messy.
Stir the dough with cheese and ham.
Arrange by tins. The dough should only fill two-thirds of the forms.
Bake for 30 minutes in an oven preheated to 180 degrees. Serve with a cup of coffee.
