Heat the oil in a deep-fryer to 365 degrees F (185 degrees C).
Separate the onion slices into rings, and set aside. In a small bowl, stir together the flour, baking powder and salt.
Dip each of the onion slices into the flour mixture until they are all coated; set aside.
Whisk the egg and cannabis milk into the flour mixture using a fork.
Dip the already floured onion rings into the batter to coat, then place on a wire rack to drain
Sprinkle the bread crumbs on a plate. Put the onion rings one at a time into the crumbs, and scoop the crumbs up over the ring to coat and pat them on hard so it sticks.
Deep fry the rings a few at a time for 2 to 3 minutes, or until golden brown. Remove to plate lined with paper towel. (this helps remove any left over grease from the oil)
If you feel like dipping, grab your favorite dip like Ranch, Marinara, or something spicy!
