Butterscotch Sauce

  • Serves

    makes 2 Cups

Cooking butter with sugar causes milk solids to caramelize, giving butterscotch sauce its delicious flavor.


  • 8 tbsp. unsalted butter (like Meggle Unsalted Alpine butter)
  • 2 tbsp. light corn syrup
  • 34 cup granulated sugar
  • 14 cup light brown sugar
  • 13 cup heavy cream
  • 1 tsp. dark rum
  • 1 tsp. vanilla extract
  • 12 tsp. fine salt
  • 12 tsp. fresh lemon juice


Step 1

Heat butter, corn syrup, and 1⁄4 cup water in a medium saucepan over medium-low heat, stirring constantly, until butter has melted.

Step 2

Stir in granulated sugar and brown sugar; scrape down sides of pan with a rubber spatula. Bring mixture to a boil over medium heat, without stirring. Cook until light brown and a candy thermometer inserted in sauce reads 245°, 6–8 minutes.

Step 3

Remove from heat; carefully add heavy cream, rum, vanilla extract, salt, and lemon juice; stir to combine. Let sauce cool to room temperature. Serve over ice cream.
