Butterscotch Blondies Are Superior
Butterscotch Blondies Are SuperiorThese butterscotch bars are full proof– just mix, spread and bake. They have that irresistible chewy, gooey texture of brownies but with a caramel-y butterscotch flavor. I love that they're fancy enough to serve guests. I like to elevate them with a scoop of vanilla ice cream and drizzle of homemade butterscotch sauce.

How to make Butterscotch Bars:
Make Cookie Dough: Cream butter and sugar until smooth then mix in egg and vanilla. Add flour and baking powder then stir to combine. Fold in butterscotch chips (reserve a little handful for sprinkling on top).
Bake: Spread into a greased or parchment lined square baking dish then bake at 350°F for about 25 minutes, or until a toothpick comes out clean. Let the butterscotch blondies cool until warm before cutting and serving.
Butterscotch Sauce: In a saucepan, melt butter then stir in sugar and cream. Bring to a boil then reduce the heat and simmer for 5 minutes, stirring often. Take it off heat then stir in vanilla (the sauce will thicken as it cools).
Serve: Move a butterscotch bar to a plate and top with ice cream and a drizzle of butterscotch sauce.

I originally shared this recipe May 2016. Updated June 2023 and January 2026.
New family favorite! We can switch out butterscotch chips for chocolate, add nuts, etc.
I also only had dark brown sugar and they turned out just fine. Thank you for this recipe – it’s really delicious! : )
Excellent and super easy! I added pecan chips.
Delicious
Made these as a treat for my husbands lab after I grabbed butterscotch morsels by mistake. Had to add salt as my butter was unsalted and added little less than 1/4 cup of milk just to help smooth it out a bit since my brown sugar wouldn’t break down.
They absolutely loved it! Will be making again!
This is sooo good! My kids and I love it! It’s easy to make and tastes so yummy! It’s literally gone in minutes! Thank you!
THIS RECIPE IS SOOOOO GOOD!!!!1
i want to make these now but only have dark brown sugar. Have you ever made them with dark before?
No, but should work just fine 🙂
Did you use a glass pan?
Glass or metal will work. Enjoy!
Thanks for the recipe! The ingredients for the sauce do not list salt. How much salt should be included?
If the sauce ingredients don’t list salt, why are you adding something that isn’t needed? I
Maybe the recipe will taste better if you add the salt. I add chocolate chips to many recipes that don’t list them as an ingredient, and the end result always tastes better.
I would add3/4 teaspoon of kosher salt it balances the sweetness
I agree with you on this Stephen!
