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. 

Butter melted in a small saucepan, then cream and brown sugar added to make a homemade Butterscotch sauce.

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.

  2. 5 stars
    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!!!

  3. 4 stars
    Super easy and yummy, but I was wondering how to adjust the cook time for a double recipe? Mine came out underdone. Thanks!

  4. 5 stars
    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.

  5. 5 stars
    The flavor of these bars is outstanding! The last few times I made them, they sank in the middle. Any advice on this?

  6. 5 stars
    These were amazing! I did alter the amount of brown sugar and granulated from 1/2 brn to 3/4 brn and 1/4 granulated and I added a small unmeasured amount of maple syrup (bourbon flavored). And it came out delicious!

    I made a double recipe and baked in a 13 x 9 glass pan for 38 minutes in a 350 degree oven. Flavor is great, I added a pinch of salt to the flour/baking soda, added chopped pecans to the top before baking. If I were to make again, I’d cut both sugars by at least 1/4 cup, especially if serving with the butterscotch topping and ice cream. They are too sweet for my taste and I have a major sweet tooth.

  8. If I wanted to add walnut pieces, what amount should I use? Should I lightly toast the nuts first? Do you think nuts would be a good addition?

  9. 5 stars
    Absolutely Fabulous Blondies! If you like blonde brownies you will love these. I only had to cook for 30 minutes. Completely addicting. I asked my husband to move them away from me. They are SO GOOD, I can’t stop eating them.

    My adult son asked where these had been all of his life!!! I’m making them for a picnic on Saturday, because my family doesn’t argue over these – they are fantastic.

    Love the recipe. I reduced both white and brown sugar to 1/3 cup each but still too sweet for me. Definitely gonna remake it. Used a glass 9×9 pan for baking so it only takes about 30-35 min to bake. Turns out perfect. Thank you for sharing!

  12. 5 stars
    Our family’s new found favorite! Moist, chewy, sweet but not chocolately. My adult son wants to know where these have been his whole life and he is a chocoholic!!!👍

    1. 5 stars
      I made these with my grandkids last week! Amazing!! My husband came home and ate half the pan they were so good! Definitely on the short list!

  13. 5 stars
    I also only had dark brown sugar and they turned out just fine. Thank you for this recipe – it’s really delicious! : )

  14. 5 stars
    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!

  15. 5 stars
    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!

  16. Thanks for the recipe! The ingredients for the sauce do not list salt. How much salt should be included?

      1. 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.
