Decadent homemade butterscotch is smooth, rich, and sweet! This sauce is made in as little as 10 minutes. Trust me when I say you'll want to eat this butterscotch on ice cream, brownies, cookies, cakes... just about everything! It's so good!
Add the butter to a medium saucepan set over medium heat. Melt butter then add the brown sugar, kosher salt, and heavy cream. Stir the mixture with a rubber spatula or wooden spoon until combined.
Bring the mixture to a boil and boil for 4-5 minutes, stirring occasionally.
Remove from the heat and stir in the vanilla extract.
Let rest for a minute or two before transferring the sauce to a heat proof container to cool. Cover and store in the fridge for 2 weeks. The mixture will thicken as it cools, so do not over-boil it otherwise it’ll be much too think and won’t be pourable.
Notes
To prevent the sauce from separating, don’t stir too much while the brown sugar is melting. Don’t cook the sauce too long, because it will thicken a lot once cooled.Keep the temperature at a moderate heat to prevent burning.What to serve with butterscotch sauce? Brownies, ice cream, peach cobbler, or make it into a milkshake!
