In a small bowl stir together the warm water and sugar until the sugar dissolves. Stir in the yeast and allow this to sit for 6-8 minutes (it should activate and will look foamy). In a large bowl stir together the flour, salt and cinnamon. Stir in the yeast mixture and melted butter until a loose dough ball forms. Turn out on to a lightly floured counter and knead for 4-6 minutes, until the dough begins to become elastic. Place in a lighlty oiled bowl, cover and allow to rise for an hour.

The dough should just about double in size. Punch down and roll out on a lightly floured surface so that it's about 1/4 inch thick. Cut into triangles, squares or other fun shapes. In a large, heavy pot heat enough oil, so the Sopapillas can float to around 375°F. Fry the Sopapillas until browned, about 2 minutes. Then flip so that each side cooks. Remove to a plate lined with paper towels to remove excess oil, sprinkle with sugar.
