Homemade Butterscotch Sauce

This has been on amazingly fun week of ice cream-related treats! The banana split ice cream cake was definitely a highlight of the summer so far, and I’ve thoroughly enjoyed trying my hand at a lot of different homemade ice cream toppings. To close out the week, I’m sharing with you an absolutely fantastic recipe for butterscotch sauce. Given my love of peanut butter and hot fudge, butterscotch has never been one of my go-to flavors when it comes to ice cream and sundaes, but I do enjoy it on occasion. As I’ve found out as I tackle more and more DIY food projects, my appreciation for a lot of things has grown immensely when I make it myself. Not only is there the satisfaction in making it from scratch, but the flavor just can’t compare to anything you get from a bottle or jar at the store. Butterscotch is definitely one of those instances – I could easily see this sauce taking up a permanent residence in my ice cream sundae rotation. It’s thick, rich and full of warm, buttery flavor. It basically tastes like the world’s best Werther’s Original (in liquid form, of course).

I’ve always thought that caramel and butterscotch were very similar, but after making both I can appreciate the differences between them. While caramel is made from melting down and cooking granulated sugar until just before it burns then adding cream and a small amount of butter, a butterscotch sauce is made by gently boiling together butter and brown sugar along with cream. There is a definite difference in flavor – the butterscotch is much sweeter thanks to the brown sugar and has that melt-in-your-mouth quality that can only be derived by a healthy dose of butter.
I love that I have so many ice cream options now; I feel like an ice cream sundae party with a toppings bar is in order!

I followed the recipe exactly and it didn’t work! Or maybe this is supposed to be a real thin runny sauce like syrup? I was hoping for a silky smooth thick sauce.
I made this butterscotch syrup and was happy at how simple the ingredients and the recipe were. I may have put a bit more salt than the recipe called for, but when I make it again, I’ll use a little less than called for. Delish! Thanks
I made this recipe for a party at a friend’s house who was serving Ice Cream for dessert. Now everyone asks for it whenever I come to a party ~ did you make Butterscotch Sauce? This is wonderful stuff and well worth the very little effort & time it takes to make it! Thanks!
Noticed majority of comments were that recipe looked delish and that commenter wanted to make it. I made the sauce and want to say that the one teaspoon of salt is way too much, especially if you are using salted butter, which I did. I would try just a small sprinkle of salt before adding anymore because I’ve got a batch of sauce that is way too salty.
Made this yesterday for my best friend as a cupcake drizzle for her Birthday as she Loves Butterscotch. Well I’m 31 and have never had homemade so was not sure of what to expect and neither did my bestie as she has only had store bought also.
Followed all directions. Let it cool and jarred it up for people to spoon on as wanted. Well I let the older family member’s try it before Birthday bestie arrived & They Absolutely LOVED IT!!!!!!! Great Grandma even snuck a cupcake with Butterscotch on it before anyone else arrived. Even the kids love it & I actually just made another batch of it so Thank You for this recipe which I will be using over and over again and I Look forward to trying more of your recipe. Especially a peanut butter one like this one if you have… Thanx Again!!!!! (Sorry for the long message) (I had to stop because it was going to be longer. Lol)
Hi Michelle,
Should you be stirring after you reduce the heat and let it boil for five minutes?
And can this be jarred and reheated or should it all be used at once?
Thanks!!
Hi Lisa, No, you should not stir while it gently boils for 5 minutes. It can be jarred and reheated.
Just made this…love it. I didn’t have the flake salt so used kosher, it’s a little saltier than the butterscotch sauces I’ve had but I love salted carmal so it’s all good. Giving this to my dad for Father’s Day…he loves butterscotch.
How do I keep the warm butterscotch from hardening when I pour it over ice cream? In other words, is there something I can add to keep it runny? Is that what light corn syrup’s for?
Hi Victoria, This didn’t harden on me, but I know what you mean – some sauces do stiffen up once they hit the cold ice cream. I’m not sure if corn syrup would help, as I’ve tried some other sauces with that in it, and they have hardened.
Maybe I just cooked it for too long. Good to know that yours didn’t harden, so I’ll keep trying. Thanks!
I made this with white sugar (tried a few things, but the brown sugar refused to be anything other than a brick) and it turned out a really weird yellow color, but it tastes ahmaazing! I used pink himalaya salt and forget to add the vanilla, and I’m not sure if it actually tastes like butterscotch, but it tastes almost exactly like “knekk”, a Norwegian christmas candy :)
Hi Michelle, do you think I could cut this recipe in half? And, how long does it last in fridge? Same with hot fudge… Thanks!
Hi Noreen, Yes, you could definitely cut this in half. You can keep it (and the hot fudge) for up to 2 or 3 weeks. Enjoy!
This looks amazing.
One question. I don’t have any fleur de sel in the house. Is it okay to substitute regular table salt? I assume much less would be needed in that case? What do you think?
Hi Kate, You could add a very small pinch of table salt. Enjoy!
Made this last night for our upcoming Ice Cream Party. Ridiculously easy to make and oh. so. good.
Love the sauce, I would cut back the amount of salt next time….just a little to salty for my taste
I wan’t it !!!! gnammy
