In a microwave safe mixing bowl place 3/4 C butterscotch chips and 1 can sweetened condensed milk. Microwave for 30 seconds and stir. Continue microwaving in 30 second intervals until butterscotch chips are melted and mixture is smooth.
Dip each frozen cupcake in the butterscotch mixture, use a fork to lift cupcake out (be careful, the little sucker stick is easy to yank out) tap off excess and roll in topping of choice. (chopped nuts, crushed oreos, mini m&m's, sprinkles, whatever sounds good to you)
place on wax paper to set up. This can take a couple hours if left on counter, the fridge will help speed it up.
To drizzle your apple cakes melt some chocolate chips in the microwave, on reduced power (I do 40%, but every oven is different) place melted chips in a sandwich bag and snip a little tiny tip off one of the corners, drizzle away!
I put these in cello bags and tied them with ribbon for extra fun give aways.
