Delicious chewy sugar cookie bars made with brown butter. This adds such amazing flavor and the salted caramel buttercream on top is the best part! Brown butter sugar cookie bars with salted caramel butter cream bars.

I love sugar cookie bars. They require little effort to make and taste just as amazing with a fraction of the work. Brown butter is also another favorite of mine. Have you made anything yet with brown butter in it? If you haven’t, then you are missing out!

How do you even describe brown butter? It becomes nutty and adds such great flavor with just a simple added step of cooking it on the stove. It is like a bakers gold. Whatever you add it to becomes amazing! It made these sugar cookie bars so soft and chewy and were literally the best that I have ever had!

But just when you think these delicious bars can’t get any better, you frost them with salted caramel buttercream. Oh my goodness. I think I am going to frost everything from now on with this frosting! The frosting took these delicious bars to a whole different and amazing level. Sprinkle it with a little sea salt and you are good to devour. 🙂

I have made some sugar cookie bars in my day that have been dry and crumbly  before. Not these. They are so soft and chewy with the first bite! They even stay soft and chewy the next day. If they last that long! 🙂

I know that you will agree that these are one of the best cookie bars ever! And if you have never added brown butter to anything, now is the time to start!

Delicious chewy sugar cookie bars made with brown butter. This adds such amazing flavor and the salted caramel buttercream on top is the best part!
Prep Time: 10 minutes
Cook Time: 22 minutes
Total Time: 32 minutes
Servings: 16 Cookie Bars


For the Brown Butter Sugar Cookie Bars:

  • 13 tablespoons unsalted butter melted until browned
  • 1 1/2 teaspoons vanilla extract
  • 1 cup dark brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs at room temperature
  • 2 cups plus 2 tablespoons all-purpose flour
  • 1/2 teaspoon salt

For the Salted Caramel Butter Cream:

  • 1/2 cup butter or margarine
  • 1 cup brown sugar packed
  • 1/4 cup milk
  • 3 1/2 cups powdered sugar
  • Course Sea Salt for Sprinkling


To make the sugar cookie bars:

  • Preheat oven to 325 degrees. Line a 9x13 inch pan with aluminum foil and lightly spray with cooking spray.
  • In a medium sized saucepan add the butter. Cook over medium heat and whisk the butter to brown. It will become frothy and start to have a nutty aroma. Then it will turn brown. It takes about 3 minutes. Remove from heat.
  • In a large mixing bowl, combine dark brown sugar, sugar, vanilla, brown butter and eggs. Beat until incorporated.
  • Add flour and salt and mix until just combined. Do not over mix. The dough will be thick. Spread evenly into the bottom of your prepared 9x13 inch baking pan. Bake for 22-25 minutes or until the edges are lightly brown. Remove from oven and allow to cool on a wire rack completely.

To make the salted caramel buttercream:

  • In a medium sauce pan add the butter and brown sugar. Bring to a boil. Stir in the milk and bring back to a boil. Remove from heat and stir in powdered sugar. Frost the cooled bars ad sprinkle lightly with sea salt.

  1. I made these bar cookies for a memorial service at our church. On Sunday morning everyone was coming up to me to praise my maple cookies ? But now they are requested specifically for any church event! Thank you for this amazing recipe!

  2. I made these last night but my frosting is not sticking to the butter sugar cookie. As soon as I start cutting the icing breaks right off. Is there something I can do to fix it? It all tastes good, together, if only I could get them to stay together. Any ideas are much appreciated.

  3. Loved this recipe! I added a little less sugar so it was less sweet. I’ll definitely be making this icing again! It was delicious.

    1. 3 stars
      These are good, but extremely sweet, and after reading the comments , I only made half of the frosting recipe and used most of it. They were still very sweet!

  4. Made these to add to my Christmas recipes. Every family member said they were the best recipe! They are very rich so I cut them 1 inch by 1 inch. Perfect! My frosting turned out a little hard and I only had light brown sugar. Still they were unbelievably awesome. Thank you for this recipe.
    Your little stars don’t work or I’d give you a ten!

  5. Hi! Could you please tell me if the dark brown sugar in the bar is packed? I would like to make them tomorrow. Thanks!

  6. Just made them. They are wonderful! Very rich so I’m cutting them in very small squares and putting them in with my Christmas cookies! Thank you!

  7. I just made these, and threw all the frosting on top without reading the reviews – it’s definitely twice the frosting needed (and I LOVE frosting). I used a 13×9, but my bars and my frosting are at least twice as thick as the picture. All that being said, these are delicious! Thanks for sharing a great recipe.

  8. Hi, these bars look great! I love browned butter! I have a question, the dark brown sugar in the cookie is not packed? The light brown sugar in the frosting is packed. I always assume that brown sugar is packed unless stated unpacked brown sugar. I was just about to make these, it seems like a small thing, but could make a difference in the sweetness level. Thanks!

  9. I used only 2 cups of powdered sugar for the frosting, and it still turned out well. The frosting recipe makes double what is necessary. Delicious!
