You can still make these without a mold. They won't be the same round shape but the concept will be the same. Place some paper cupcake liners into a muffin tin. Spray with nonstick cooking spray. Place some of the melted chocolate into the muffin tin and brush it up the sides - taking care that it's not too thick. Once it dries, add in the filling. Then top with another layer of the melted chocolate. Again, you don't want the chocolate overly thick or it will take it longer for the chocolate to melt in the warm milk. Decorate and prepare as listed below.
