Into a bowl, add the milk powder and the condensed milk, mix very well into a dough. Set aside.
Melt 90g of milk chocolate in the microwave, in 30-second intervals. It can also be melted in a double boiler.
Transfer the melted chocolate to a silicone mold, spreading it all over the bottom. I’m using a 20cm x 12cm mold.
After that, set aside.
Grease your hands with butter and grab some of the milk powder dough, roll it into balls of different sizes.
Put the dough balls on top of the chocolate into the mold, placing them together, one next to the other.
Melt another 90g of milk chocolate and pour it over the balls, fully covering them.
Take it to the fridge and leave it there for about 30 minutes.
After the indicated time, unmold and serve.
