Grab a large saucepan and combine the butter, sugar, and milk over medium-high heat. Stir everything together and bring the mixture to a rolling boil. Once it's bubbling vigorously, let it boil for exactly one full minute - don't skip this step as it helps everything set properly later.

Remove the hot saucepan from the heat immediately after your minute of boiling. Quickly stir in the vanilla extract, salt, and butterscotch chips. Keep stirring for about 1-2 minutes - don't worry if the butterscotch chips don't melt completely, they're supposed to stay a bit chunky for texture.

Gently fold the dry quick oats into your butterscotch mixture until everything is well combined. Using a large cookie scoop or tablespoon, drop generous portions of the mixture onto parchment paper, spacing them slightly apart. Let them rest at room temperature for about 15 minutes until they're completely set and firm to the touch.
