Preheat grease in fryer to 350 F
Remove skins from onions and slice into roughly 3/4 inch slices - then separate the rings
In a large bowl, combine pancake mix, cayenne pepper, paprika, chili powder and salt and pepper
Slowly pour in buttermilk and stir well. Batter will be thick, but you can add additional butter milk if batter is too thick for your liking.
In a separate bowl, pour a generous amount of bread crumbs to use for coating the onion rings
Dip each onion ring into into the batter, followed by dipping them into the bread crumbs
Fry the onion rings in the grease for 1:30 - 2 minutes - only doing 2-3 rings at a time to prevent from sticking together
Remove from grease and allow to cool on a wire rack on top of paper towels - add additional salt if necessary
Serve with sweet heat onion ring dipping sauce and enjoy
