Line either a 9X9 or an 8X8 pan with foil or parchment paper and then spray it with a non-stick cooking spray.
Place the butterscotch chips and sweetened condensed milk in a microwave safe bowl. Microwave the mixture in 20 second intervals, stirring after each interval, until the chips are completely melted.
Then stir in the vanilla extract and salt. Pour the mixture into the prepared pan.
Cover the pan and refrigerate for 2-3 hours until the fudge is firm.
Carefully remove the fudge from the pan, cut the fudge into squares and it’s ready to serve and enjoy!
Notes
