Turn onto a floured surface and knead several times. Divide dough into 8 equal pieces. Flatten each piece into a thin circle.
Heat about 1/2 inch of vegetable oil in a cast iron skillet or heavy pot to 365˚F (use a thermometer and maintain an even temperature).
Use tongs to carefully add dough rounds (1 or 2 depending on the size of your pan) to the hot oil. Fry for about 1 minute on each side until golden brown.
Drain on a paper towel lined plate. Sprinkle with cinnamon sugar while warm.
