Using the purple-handled #16 scoop, measure 5, 20g level scoops of cold bunuelos dough into a 325 degree fryer. Use the same fryer as your churros.
The dough will sink to the bottom of the fryer basket, then float to the surface of the oil. They may need a gentle shake to knock them loose from the bottom of the fryer. Ladle some hot oil over the frying bunuelos to "set" the shape. Then, set another fryer basket on top of the bunuelos to submerge them.
Fry until deep golden brown, approximately 4 minutes.
Drain well on paper towels.
While still hot, toss into cinnamon sugar to lightly coat. You do not want a heavy, clump-y sugar coating.
