Carefully place 3 to 4 cronuts in the hot oil and fry for 30 seconds to 1 minute on each side or until golden brown. Remove with a skimmer to a paper towel lined pan or rack. While cronuts are still warm, dip bottom and sides in maple sugar (do not dip the top). After frying all ten cronuts, fry the small round holes until golden. Remove to paper towels. Roll cronut holes in maple sugar while still warm.
