These easy Butterscotch Blondies are chewy, soft, and made with butterscotch chips. Enjoy them plain, or served with a scoop of ice cream and an easy homemade butterscotch sauce.

Do you love dessert bar recipes as much as me? You have to try Butterfinger Bars, S’mores Bars, Sugar Cookie Bars, or the World’s Best Peanut Butter Bars!

Three easy Butterscotch Bars stacked on a counter, ready to enjoy.

Why I love this recipe:

  • Perfect Texture – Soft, thick, and chewy with the butterscotch sweetness everyone loves.
  • Next Level – They taste great as they are, or you can add a scoop of vanilla ice cream with an easy homemade butterscotch sauce. SOO GOOD!
  • Crowd PleaserCookies are always great, but I find myself making brownies and bars more! They are faster, only bake once, and are easily sliced to serve a crowd! And these bars are unique and will be the highlight of any party.

How to make Butterscotch Bars:

Cream Butter and Sugar: Add the butter, sugar and brown sugar to a mixing bowl and cream together until very smooth. Add egg and vanilla and mix well.

How to make Butterscotch Sauce:

Make Sauce: Melt the butter in a saucepan over medium heat. Add the sugar and cream and stir well with a wooden spoon until blended. Bring mixture to a boil, reduce heat and boil for about 5 minutes, stirring often. Remove from heat and stir in vanilla. The sauce will thicken as it cools.

Serve butterscotch bars warm with ice cream and a drizzle of easy butterscotch sauce.

Storage and Freezing Instructions:

To Store: Keep butterscotch blondies in an airtight container at room temperature. I think they taste best the day they are made, otherwise freeze them, for best results. Refrigerate homemade butterscotch syrup in an air-tight container.

To Freeze: Cover pan with a double layer of aluminum foil, or store cut bars in an air-tight freezer-safe container. Freeze bars for up to 3 months.

    I read the reviews and adjusted accordingly. I added salt, and i decreased both sugars to 1/3 cup. It was still too sweet for me. I think some roasted, chopped pecans would help.

    These are PERFECTION!! So good, I didn’t change a thing! Reminds me of the blondies I used to get from Applebee’s back in the day! Don’t sub the sauce for caramel drizzle-make the sauce-you’ll be so happy you did-just amazing!! Thank you!!!

    Super easy and yummy, but I was wondering how to adjust the cook time for a double recipe? Mine came out underdone. Thanks!

    These were FANTASTIC! I was concerned that they might be too sweet, but I kept all the measurements exact and took the advice of another Reviewer and added 3/4 tsp of Kosher salt. Exceptional! Love them and so does my family. Thank you for the recipe.

    The flavor of these bars is outstanding! The last few times I made them, they sank in the middle. Any advice on this?
