This butterscotch sauce recipe takes one saucepan, five ingredients, and about ten minutes. Butter and dark brown sugar melt down, bubble for a bit, then get whisked with cream into a silky sauce that tastes like it came from a fancy dessert shop. Drizzle it over ice cream sundaes, swirl it into your coffee, or mix it into frosting like my small batch Swiss meringue buttercream. It’s literally liquid gold. If you love that deep brown sugar flavor, my Ritz cracker toffee and See’s Candy fudge are right up your alley too.

Ingredients You’ll Need (and Why)
- Dark brown sugar: This is where the classic butterscotch flavor comes from. The extra molasses gives it that deep, toffee-like taste caramel doesn’t have.
- Heavy cream, room temperature: Creates the smooth consistency and helps the sauce thicken as it cools. Set it out early, because cold cream can make the sauce seize.
- Unsalted butter: The rich base of the sauce and the reason it’s so silky. Since it carries most of the flavor, use a good one.
- Light corn syrup (optional): This is my secret for a sauce that stays silky in the fridge. Corn syrup is a different type of sugar than brown sugar, and it gets in the way of the sugar crystals trying to re-form as the sauce sits. That means no gritty texture, even after a couple of weeks. You only need 2 tablespoons, and you won’t taste it. Skip it if you’re using the sauce right away.
Kosher salt and vanilla round it out. Full ingredient amounts are in the recipe card.
Substitutions and Add-Ins
- Bourbon or dark rum: stir in 1 to 2 tablespoons along with the vanilla for a grown-up twist.
- Fine sea salt: use ¼ teaspoon in place of the ½ teaspoon kosher salt.
How to Make Butterscotch Sauce
- Add everything to the pan. Put the butter, dark brown sugar, corn syrup (if using), and salt in a heavy-bottomed saucepan over medium heat.
- Stir until glossy, then let it bubble. Stir with a heatproof spatula as the butter melts. It’ll look like wet sand at first. Keep stirring until the sugar dissolves and it turns smooth and glossy, then stop stirring and let it bubble gently for a couple of minutes to deepen the flavor.
- Whisk in the cream. Slowly pour in the room-temperature cream while whisking constantly. It will bubble up, then settle into a smooth sauce. Cook to 220°F for a pourable drizzle or 225°F for a thicker, scoopable texture.
- Finish and jar it. Take it off the heat and stir in the vanilla (plus a splash of bourbon or rum if you’d like). Let it cool for about 10 minutes, then pour it into a mason jar. It thickens as it cools.
Expert Tips
- The most important thing is to avoid overcooking. Once it goes too far, the texture can turn grainy or chewy and the flavor will be off.
- Use room-temperature cream for the silkiest sauce. Cold cream can cause it to seize at first.
- Whisk constantly while adding the cream so everything emulsifies into a lump-free sauce.
- High-quality butter really enhances the flavor. An Irish, Amish, or European-style butter is great here.
- Don’t rush it. Those couple of minutes of bubbling before the cream goes in are what give the sauce its deeper, richer flavor.
Butterscotch Sauce FAQs
They look similar, but the base ingredients differ. Caramel sauce is made by cooking white sugar until it melts and turns golden brown, which gives it a slightly bitter, toasty flavor (here’s my caramel sauce recipe if you want to compare). Butterscotch starts with brown sugar and butter, so it’s deeper and more buttery, with notes of molasses.
You can, but go for dark brown sugar if you want that classic butterscotch depth. Light brown sugar gives the sauce a more caramel-style flavor.
If your sauce turns gritty, some of the sugar has crystallized. Whisk in 1 to 2 tablespoons of warm water and reheat gently until it smooths out again.
Keep it in a sealed glass jar or airtight container in the fridge for up to 2 weeks. To bring it back to a silky, pourable consistency, reheat it in the microwave in short bursts or over low heat on the stove. Don’t let it boil again, or it could burn.
Yes! Freeze it for up to 3 months. Thaw it overnight in the fridge, then reheat slowly and stir until it’s silky again.
