How to Make Butterscotch Sauce

Real butterscotch sauce has nothing to do with those hard candies. It's brown sugar and butter cooked until they smell like toffee, then smoothed out with cream into something that pours warm and thick over ice cream or cake.

Before you start

Keep your cream at room temperature and whisk ready

Cold cream will seize the hot sugar mixture, creating lumps that won't smooth out. Have everything measured before you start—once the sugar begins cooking, it moves fast.

Ingredients

The melt

Cook until it smells nutty, not just melted

The brown sugar and butter need to bubble and foam together for 2-3 minutes after melting. You'll smell the difference—it goes from sweet to rich and nutty.

Step by step

  1. Melt the sugar and butter together. Combine brown sugar and butter in your saucepan over medium heat. Stir until melted, then let it bubble and foam for 2-3 minutes until it smells nutty and turns deep amber.
  2. Add the cream slowly. Pour in the room-temperature cream while whisking constantly. The mixture will bubble up dramatically—keep whisking until it settles into a smooth sauce.
  3. Finish with vanilla and salt. Remove from heat and whisk in vanilla and salt. The sauce should coat the back of a spoon but still pour easily. If it's too thick, whisk in cream a tablespoon at a time.

Questions

Can I use light brown sugar instead of dark?
Yes, but the flavor will be milder. Dark brown sugar has more molasses, which gives butterscotch its distinctive depth.
How do I fix butterscotch sauce that's too thick?
Warm it gently and whisk in cream or milk one tablespoon at a time until it reaches the right consistency.
Why did my sauce turn grainy?
Usually from adding cold cream to hot sugar. Warm the sauce gently and whisk in a bit of warm cream to smooth it out.
