Easy Butterscotch Sauce Recipe You Can Make in 10 Minutes

Brown sugar and butter melt together into a glossy, deeply golden sauce that ribbons off the spoon in a thin stream. This butterscotch sauce recipe skips the caramelizing step entirely, so everything goes into one pan cold and comes out ten minutes later, ready to pour over ice cream while it’s still warm.

Grab your saucepan and let’s make it!

Why You’ll Love This Recipe

• Everything goes into the pan at once, cold = no need to watch the sugar and hope you catch it in time
• Ten minutes on the stove from start to finish
• Six ingredients (and the sixth is optional!)
• One batch fills a jar and keeps for a week – your sundae nights = covered!
• If you’ve ever had a Werther’s Original candy melt slowly in your mouth, that’s the flavor you’re chasing here, in pourable form

When and Who This Is For

This sauce comes out of my fridge most often for sundae night, when everyone builds their own and the counter disappears under bowls of sprinkles and cherries. A jar of cocoa syrup alongside gives everyone a chocolate option too. Plain vanilla ice cream is the best for this, because it gives the sauce a canvas to shine on.

Here’s what else you can use it for:

• Warmed over apple crisp or bread pudding once the weather turns
• A spoonful stirred into coffee for something better than plain milk
• Poured into a small jar and tied with a ribbon, for a teacher gift or a holiday basket
• A build your own sundae bar for a birthday, or a Friday night when the kids need an event
• Hot afternoons when turning on the oven is out of the question

It’s vegetarian, and naturally gluten free since nothing in it contains wheat. It does contain dairy from both the butter and the cream, so it isn’t one for dairy free guests. If that’s who you’re feeding, my silky vegan caramel sauce uses coconut cream instead and does the same job.

Ingredients for Homemade Butterscotch Sauce

• 1 cup packed light brown sugar (220 g)
• 4 tablespoons salted butter, room temperature (57 g)
• ½ cup heavy cream (120 ml)
• 2 tablespoons corn syrup (30 ml)
• ⅛ teaspoon salt
• 1 teaspoon vanilla extract (5 ml), optional

A few notes on the ingredients:

Light brown sugar is the whole identity of the sauce, since the molasses in it is what makes this butterscotch rather than anything else. Dark brown sugar works and gives you a deeper, more assertive molasses flavor, but it also darkens the color noticeably.

Room temperature butter melts at closer to the same rate as the sugar dissolves, and that evenness is what keeps the fat from pooling on top.

Corn syrup is doing quiet insurance work here. It interferes with the sugar’s ability to form crystals, which is the main thing that goes wrong in a sauce like this.

Salted butter plus ⅛ teaspoon of salt gives you enough to keep the sweetness from flattening out. This isn’t a salted butterscotch sauce, it’s a balanced one.

How to Make Butterscotch Sauce

1. Everything into the pan, cold.

Add the brown sugar, butter, heavy cream, corn syrup, and salt to a saucepan. No melting anything first, no order to follow. Use the heaviest bottomed pan you own if you have a choice, because thin pans build hot spots and hot spots can cause a sauce like this to split.

2. Set it over medium-low and stir as it comes together.

Stir frequently while the butter melts and the sugar dissolves. Medium-low heat is the way to go here – butter and sugar melt at different rates, and pushing the heat means the butter races ahead and separates out into a slick on top before the sugar has caught up.

3. Cook for 6 to 8 minutes, stirring often.

Keep going until it looks smooth and fully combined with no grit of undissolved sugar left in the bottom. This is the step worth being patient about, since sugar that hasn’t fully dissolved before things start bubbling is what turns a sauce grainy later.

4. Let it simmer to the thickness you want.

It’s ready when it lightly coats the back of a spoon. Here’s the part that trips people up: it will look thinner than you expect while it’s hot, and that’s correct. It thickens considerably as it cools, so judge it off the heat rather than in the pan.

5. Off the heat, stir in the vanilla.

Adding it now rather than during cooking keeps the flavor from cooking off.

6. Cool for 5 to 10 minutes before serving.

Straight off the stove it’s hot enough to melt a scoop of ice cream into soup. A short rest brings it down to a drizzling temperature while it’s still warm and pourable. Serve it now, or cool it completely and move it to a container in the fridge.

Tips and Variations

• If it looks grainy, the sugar didn’t fully dissolve before it came to a boil. Pull it off the heat, stir in a tablespoon or two of warm cream, then bring it back gently until it smooths out.
• If it looks oily or split, take it off the heat immediately. That’s a temperature shock, usually from heat that crept too high. Stir hard, and add a tablespoon of hot water or cream if it needs help coming back together.
• For a thinner sauce, stir in 1 to 2 tablespoons of heavy cream after cooking.
• For a thicker butterscotch sauce, let it simmer another 1 to 2 minutes, stirring frequently.
• A pinch of flaky sea salt over the top turns it into a salted butterscotch sauce with a bit more contrast.
• A splash of bourbon or a teaspoon of espresso powder stirred in with the vanilla adds depth to the flavor.

Ways to Use It

Over ice cream first, always. Warm butterscotch sauce for ice cream is the whole reason to keep a jar in the fridge, and it’s especially good with plain vanilla, where nothing else is competing for attention. Set out sprinkles, chocolate chips, crushed cookies, and cherries, and let people build their own.

After that:

• Spooned over brownies, pound cake, or a slice of anything plain;
• Warm over apple crisp or bread pudding
• Stirred into hot coffee, or drizzled over an iced one;
• Poured over pancakes or waffles instead of syrup;
• As a dipping sauce for apple slices, thickened with an extra minute of simmering;
• Drizzled over banana pudding, which is the pairing this sauce was practically invented for.

It also jars up beautifully. Pour it into a small glass jar once it’s fully cool, add a label with the date and a note to keep it refrigerated, and it becomes a gift that takes ten minutes.

Before You Go

There’s something about a jar of sauce in the fridge that changes what a Tuesday can be. Ice cream stops being ice cream and becomes a sundae, coffee gets a little better, and none of it took planning. Make a batch this weekend, put out some bowls of sprinkles, and let everyone build their own. Save this one to Pinterest so it’s there the next time somebody asks what’s for dessert.
