Roll out the dough very thin, about the thickness of a dime. I have even used a pasta roller to achieve this.
Cut out 5" ovals (can use a cardboard cutout as a stencil).
Loosely wrap each oval piece of dough around the metal cannoli tube
Seal the edges where they overlap with a dab of non-dairy milk.
Deep fry in 2" of oil at 400"f.
Remove when golden brown all over (about 2 mins).
Drain on paper towels and let cool briefly before removing the metal tube/forms.
Let cool completely before filling.
