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!

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!

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

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.

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.
