Combine butter, sugars, corn syrup, and salt in a pot on the stovetop.
Bring the mixture to a boil, stirring constantly. Stir in evaporated milk, and later the vanilla.
Pour the caramel mixture into a parchment-lined pan, and move it to the fridge to cool.
Finally, use a sharp knife to cut the caramel into bite-sized squares.
