Poke holes in roll centers and stretch to form donuts with large centers. Place on large sprayed baking sheets. Cover with sprayed plastic wrap and let rise until double.
Pour oil, 3 inches deep in small saucepan or electric frying pan and heat to medium high. Remove wrap and fry donuts on each side 30-45 seconds or until golden. Remove to paper towel to drain. Combine all glaze ingredients until mixed well. Dip cooled donuts into glaze to coat top. Sprinkle top with toasted coconut and lime zest.
