Why this Recipe Works
Butterscotch is like the forgotten flavor.
It’s so rich and delicious, but people always tend to choose chocolate, peanut butter, or lemon desserts over butterscotch.
But can I be honest here? I think Butterscotch is my favorite of all flavors. Today’s Butterscotch Marshmallow Bars are a hidden gem of a dessert.
It’s what you get when you want a Butterscotch s’more. Something sweet and gooey…that’s not all chocolate.
And when you eat these chilled out of the refrigerator? Whole new level of flavor!

How to make Butterscotch Marshmallow Bars
Prep. Preheat oven to 350 degrees F. Line a 13×9 baking dish with parchment paper. Set aside.
Melt Butterscotch. In a small glass bowl (or other microwave safe bowl), melt butterscotch morsels with butter in the microwave for 30 seconds. Stir, heat an additional 30 seconds. Stir, if not smooth yet, heat an additional 15 seconds.
Make Batter. In a large mixing bowl, add brown sugar, eggs, and vanilla extract. Mix in melted butterscotch chips, flour, baking powder, and kosher salt.
Fold in marshmallows and chocolate chips. Pour batter into prepared baking dish.
Bake for 18-22 minutes, until lightly browned. Cool completely.
Refrigerate at least one hour. Cut into bars and enjoy!
Tips and Tricks
- Parchment Paper. Definitely use it. It will keep these gooey, sticky bars from sticking to the pan. Don’t accidentally use foil or wax paper, won’t have the same results.
- Storage. These bars taste best when chilled, but can be stored in airtight container at room temperature.
- Freeze. You can freeze these bars by wrapping in plastic wrap then sliding into freezer safe ziploc or airtight container. Freee for up to 3 months.
- Substitutions. Swap out the butterscotch morsels for peanut butter morsels. You’re welcome!

My childhood sundae of choice. Butterscotch. I need these in my life! Thanks for sharing!!
Just made these and they are great! SO sweet, though, so everyone be warned! In fact, you should probably list milk as a required ingredient because you’re gonna need some after you’ve had a bite or two! Thanks for the yummy recipe!
haha, they ARE super gooey and sweet. Perfect for sharing 🙂
I just made these for my kids and, yum! I’m just curious if they need to be refrigerated safety or is that just a cold vs. room temp preferance? I noticed the last step is refrigerate for 1 hour.
Thanks for sharing! I’m going to try them with a scoop of vanilla ice cream 🙂
I found leaving them out turned them even gooier (is that a word??). You can totally leave them out safety wise 🙂 glad you enjoyed them!
I have made these 3 times in the last two weeks, they usually last 1 day and there are only 3 of us. I have found using self rising flour creates the best outcome. It’s the only flour I had the first time so I took a chance and they come out so much better then with flour and baking powder., consistency wise. Delicious.
What about using this as a brownie topping…
I think that sounds delicious 🙂
I made these instead of a birthday cake this year. (Wrote about it here) They were perfect. Thanks so much for the recipe. 🙂
what can i use instead of butterscotch morsels? i can’t find where i live
You could try peanut butter morsels!
Eat the whole pan…are we twins?! I’m making this the next time my kids are gone for the whole day.
Girl, you have done it again! I was really wanting to bake something and found this wonderful recipe! I have all the ingredients and it’s in the oven now! My hubby is sooo excited he loves butterscotch!
Any ideas if I can sub Marshmallow Creme for the mini marshmallows as that’s all I have at hand?
I haven’t tried it, but you can certainly try. I wouldn’t use the same amount as marshmallow though, maybe half? So 1 cup? WOrse case scenario is even gooey’er. Not a bad thing.
Ohhh, looks so good. Perfect for Father’s days:)

New to your blog- I searched “butterscotch” in my google reader and saw your recipe from Tatertots and Jello and made them for company tonight. They were a hit! Thanks for the great recipe!
I haven’t got to try these…but I am making a SECOND batch because my cat was trying them, and stepped in the pan while they were cooling. 🙂
Thanks for all your amazing work. 🙂
Oh my gosh! These look like the best things I have ever seen. I am seriously drooling.
