This is the best chewy blondie recipe! Buttery, soft, and simple to make (no mixer required!) I think you’re going to really love these!

This recipe is very similar to my well-loved chocolate chip cookie barsand is every bit as good! My Blondies recipe includes options for mixing in chopped nuts or white chocolate chips, but these cookie bars taste just as good without any add-ins at all. Be sure to check out my how-to video at the bottom of the recipe!

The Best Blondie Recipe (1)

Thank goodness I had this easy blondie recipe planned to share today!

If you’ve been following my Instagram stories you already know that Zach and I are fostering three 7-week old puppies. They are thecutest, goofiest, fluffballs I’ve ever seen,but they’re also exhausting,so excuse me if a few of my sentences are a little incoherent today.Bonus puppy pics at the bottom of the post!

But back to the blondies.

Buttery, soft, chewy, loaded with your favorite add-ins, these cookie bars are packed with flavor and they are the perfect easy snack when you need a dessert in a pinch.Fortunately today’s recipe is super simple because I don’t know that I’d have the brainpower to focus on anything even mildly complex right now, but I do have a few tips and other info I want to share with you.

What is the Difference Between a Blondie and a Brownie?

The main difference between a blondie and a brownie is the chocolate.

Blondies are occasionally referred to as “blonde brownies”. They are made without cocoa powder and aspire to a rich vanilla flavor rather than a deep chocolate one. Blondies are also often made with brown sugar, and while I do use brown sugar in my brownies, the flavor has a more noticeable affect in the blondies (more on that below).

Here’s my favoritebrownie recipe if you’re in the mood for something chocolatey!

Tips for Making Blondies

  • You can use all light brown sugar, all dark brown sugar, or a combination of the two for this blondie recipe. I like to use half light and half dark. Keep in mind that if you use all dark brown sugar your blondies will have a richer, sweeter taste and a more moist texture.
  • Melting the butter for this recipe gives the blondies a buttery taste and a soft, chewy texture. I much prefer melting the butter to creaming my butter and sugar when making blondies and cookies for this very reason (I do the same thing with my chocolate chip cookies).
  • The extra egg yolk and the cornstarch are also key ingredients for making these blondies soft and chewy. I talked a lot about why I use cornstarch in my recent pumpkin bar recipe, if you want more information on that!
  • You can add up to 2 cups of your favorite add-ins to this blondie recipe. I listed a mix of chopped walnuts and white chocolate chips in the recipe. I found that this combination provided a nice balance of sweetness and crunch. Of course, you can also leave the add-ins out completely!

Alright, well I have two puppies pulling on my shoelaces right now and another that’s determined to devour my couch, so I’m off to take care of that. Enjoy!

Author: Sam Merritt

Ingredients

  • 1 cup (226 g) unsalted butter melted
  • 1 ¼ cup (250 g) brown sugar* tightly packed
  • ½ cup (100 g) sugar
  • 2 large eggs + 1 egg yolk room temperature preferred
  • 2 teaspoons vanilla extract
  • 2 ¼ cups (285 g) all-purpose flour (note that in the video I accidentally said 2 ½ cups flour, that is incorrect, you only need 2 ¼ cups as written here)
  • 2 teaspoons cornstarch
  • ½ teaspoon baking powder
  • 1 teaspoon salt
  • cup (115 g) white chocolate chips
  • 1 cup (130 g) chopped walnuts

Instructions

  • Preheat oven to 350F (175C) and line a 13x9 pan with parchment paper**

  • Combine melted butter and sugar in a large bowl and stir well.

    1 cup (226 g) unsalted butter, 1 ¼ cup (250 g) brown sugar*, ½ cup (100 g) sugar

  • Add eggs, egg yolk, and vanilla extract and stir until completely combined. Set aside.

    2 large eggs + 1 egg yolk, 2 teaspoons vanilla extract

  • In a separate bowl, whisk together flour, cornstarch, baking powder, and salt.

    2 ¼ cups (285 g) all-purpose flour, 2 teaspoons cornstarch, ½ teaspoon baking powder, 1 teaspoon salt

  • Gradually stir dry ingredients into wet until completely combined.

  • Fold in white chocolate chips and nuts, if using.

    ⅔ cup (115 g) white chocolate chips, 1 cup (130 g) chopped walnuts

  • Spread blondie batter into prepared pan and transfer to oven.

  • Bake on 350F (175C) for 25-30 minutes*** or until a toothpick inserted in the center comes out clean or with a few fudgy crumbs.

  • Allow to cool before cutting and enjoying

Notes

* I like to use half dark and half light brown sugar in this recipe. You can use all light or all dark, either will work, but if you use all dark brown sugar the blondies will be a bit richer, sweeter, and more moist.

**If you don't have parchment paper you can lightly grease and flour the sides and bottom of your pan instead.

***If you use a glass pan it will likely take longer than the suggested time to bake.

      That’s so strange, Lynn. I’ve never had that happen so I’m not sure what happened; you can see from the photos and video they definitely shouldn’t be cakey. Did you use a scale to measure?

    These look amazing! I wanted to make them in an 8 x 11 inch pan. Would this work? Can you tell me how I should adjust the baking time/temp?

      Hi Robyn! I think it could work if your pan holds all the batter. I’m not sure on a bake time, but the temperature would remain the same. 🙂

    I have made these more times than I can count now and they are amazing every time. My favorite mix in is a third cup of dark or milk chocolate chips. The bite of blonde brownie with a small hit of darker chocolate is heavenly! They never last long around my house!

    I don’t know what I did wrong. But it wasn’t chewy or flaky top. it was cake like texture. I followed the recipe. I don’t like the caky texture .

      Hi Amanda! I’m sorry to hear this! These should be pretty dense. If they came out cakey, my best guess would be that they were over-baked or there was a bit too much flour added into the dough. 🙁

    These are great. I started making blondies in the 80’s when working for Rosies’ Bakery in Cambridge, Ma, as a froster. Your recipe is exactly like hers and she also used cornstarch. I also read somewhere that when using Pyrex or glass we need to reduce heat by 25 degrees—but we also need to add an additional 10 minutes. I saw your recipe notes but one of those equations was missing.

    This recipe checks all the important boxes:1- Delicious, 2-Easy to make, 3- No weird ingredients, made from things I usually have on hand, 4-Can be thrown together really quickly, makes a good last minute dessert recipe for company (or yourself). Like every other recipe we’ve tried from Sam, this does not disappoint.

    These turned out great, and they are not cloyingly sweet like some blondies. I baked them 27 minutes, and they came out with that crackly top and (once they were completely cooled) a nice, chewy—but set—center. Thanks also for including gram measurements as well as a link to your preferred method of measuring dry ingredients. Too often errors occur because the recipe author is a “dip and sweeper” while the person following the recipe is a “spoon and leveler,” or vice versa.

    I made these for my son’s baptism and they’re amazing! I subbed pecans for the walnuts (southerner here!) and left out the chocolate chips. Absolutely delicious! These might just become my go to treat.

FAQs

Is baking soda or baking powder better for blondies? ›

However, if you prefer blondies with a slight rise, adding 1/2 teaspoon of baking powder will yield 1-inch-thick blondies with a uniform texture. Using baking soda is not recommended for this recipe, as it can cause the blondies to rise unevenly, resulting in tall, chewy edges and a thinner, fudgier center.

Are blondies supposed to be gooey in the middle? ›

Yes, blondies should have a gooey middle and be chewy. Don't overbake them or they will be dry.

What is the difference between a brownie and a blondie? ›

Blondies use vanilla extract and brown sugar instead of cocoa powder to get their flavor, while brownies use chocolate and cocoa. Plus, brownies usually include white sugar instead of brown sugar. So, now that you know the differences between brownies and blondies, it's time to try your hand at your own brownie recipe.

How to tell if blondies are done? ›

Baking time: We found that 25 – 28 minutes was perfect for a more soft and gooey center, while 30 to 35 minutes resulted in a more firm center and more golden edges. Visual cues: Blondies are done baking when the middle is slightly jiggly and shiny on top, but the edges look solidified.

What happens if you use baking soda instead of baking powder in brownies? ›

If you accidentally add baking soda instead of baking powder to baked goods, they won't rise because there is not enough acid. To fix this, add about one tablespoon of white or apple cider vinegar for every half teaspoon of baking soda to the liquids before mixing with the dry ingredients.

What can I use instead of baking powder in blondies? ›

For every teaspoon of baking powder, you'll want to substitute in ¼ tsp of baking soda with ½ tsp of cream of tartar. If you don't have any cream of tartar, you can also substitute one teaspoon of baking powder with a mixture of ¼ tsp of baking soda plus ½ tsp of either vinegar or lemon juice.

How do you tell if a blondie is undercooked? ›

It shouldn't jiggle but it may look a bit underdone and feel soft when you press it. That's perfect as the blondie will continue to cook in the pan after you take them out of the oven. For more cakey blondies, bake them until the center is set and feels relatively firm when you press it with a finger.

Why do my blondies taste like cake? ›

Why do my blondies taste like cake? If your blondies have a texture like cake, they are overbaked. We always recommend an oven thermometer for temperature monitoring so nothing gets over- or underbaked.

Can I put undercooked blondies back in the oven? ›

If your baked goods are undercooked:
  1. If they are only slightly undercooked, you can try returning them to the oven and baking for a few more minutes.
  2. If they are significantly undercooked, you may need to extend the baking time significantly.

Blonde Brownies Recipe tips

Why are my blondies falling apart? ›

Blondies are supposed to be fudgy, gooey, and chewy in the middle. However, they shouldn't be falling apart. If your blondies are coming apart in your hands, it's likely for one of three reasons: You didn't aerate the eggs enough.

Why is my blondie raw? ›

Use an oven thermometer to ensure that your oven is reaching the correct temperature. Pan size: If you're using a pan that's too large for your batter, your blondies may be spreading too thin and baking too quickly on the edges, while remaining raw in the middle. Make sure to use the correct size pan for your recipe.

Do brownies need baking soda or powder? ›

Many brownie recipes don't contain baking powder or baking soda; these recipes tend to be for the dense, sometimes chewy, kind. Cakelike brownies usually contain a leavening agent, which helps give them their fluffy texture. The technique you use also makes a difference in the texture of the final product.

Should I bake with baking soda or powder? ›

Remember that baking soda is 3-4 times stronger than baking powder, so you'll need a lot more baking powder to get the same leavening action. As a general rule, triple the amount of baking powder for the amount of baking soda called for in a recipe. For example, 1 teaspoon baking soda = 3 teaspoons baking powder.

Does baking soda or baking powder make baked goods rise? ›

Baking soda is sodium bicarbonate, which requires an acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments.

Which is best for cake baking soda or baking powder? ›

Baking powder is baking soda with a powdered acid, so it leavens on its own. If you don't see an acid in the recipe like buttermilk, vinegar, or lemon, you're going to need baking powder. If you use baking soda instead of baking powder, it'll be bitter and won't rise.
