Brown Butter Blondies
Happy Wednesday! I can’t wait to tell you all about today’s recipe, but first, can we just catch up for a minute? I miss our weekly chit chat! So. How are you? Any exciting February things happening in your life? Any recipe requests you need me to get working on? I’m listening 🙂
Life on this side has been a healthy balance of happy and hectic. I’m working on a few exciting projects for 2016 that are keeping me very challenged and very busy. I can’t wait to share them with you later this year. I also cannot wait for the weekend. Margarita, please!
Chocolate Chunk Walnut Blondies
Now that we’ve properly caught up, it’s time for dessert! And get excited, because these brown butter walnut chocolate chip blondies are worth the fuss. To make this recipe in your own kitchen you’re going to need flour, brown sugar, butter, salt, an egg, cinnamon, walnuts, and chocolate chips. That’s it!
How to Brown Butter
The first step of this recipe is browning the butter.
If you’ve never done this before, don’t worry; it’s a very easy step and requires just a pan, a stick of butter, and a touch of patience. You’ll start off melting the butter in a skillet. Once the butter has completely melted, you’ll continue to cook the butter, on medium heat (or medium-low if your stove top runs hot), until it’s turned a golden brown and smells slightly nutty. Just be sure you stay stove side once the butter has melted; browned butter can turn into burnt butter very fast.
I chose to bake my blondies in a loaf pan pan which resulted in SUPER thick and crispy edges and extremely soft centers, but you can also use an 8-inch square baking pan for a more uniformly even blondie. So ya know, options!
My biggest piece of advice when it comes to this recipe? Don’t over bake your blondies! When you pull them from the oven they may look a little wiggly wobbly in the center… this a very good thing, my friend. They firm up a great deal during the cooling process. Plus, I’m pretty sure no one has ever complained of a gooey blondie before. Ya feel me?! 🙂
P.S. These blondies – like most blondies – are VERY adaptable. If you don’t like walnuts, feel free to leave them out or substitute another nut in their place. If you don’t like semi-sweet chocolate, feel free to use milk chocolate or dark chocolate instead. I think you get my point?
Fresh from the oven, these blondies literally melt in your mouth. Thick, chewy, crunchy, loaded with chocolate, and perfect with a cup of coffee. They pretty much meet all of my breakfast/ snack/ dessert requirements.

Brown Butter Walnut Chocolate Chip Blondies
- 1/2 cup unsalted butter (1 stick)
- 1 cup light brown sugar, packed
- 1 large egg, at room temperature
- 1 cup flour (be sure not to pack your flour)
- 1/2 teaspoon baking powder
- 1/2 teaspoon cinnamon
- 3/4 cup semi-sweet chocolate chips (or use chocolate chunks, which I do ALL the time!)
- 1/2 cup toasted walnuts, chopped
- 1/2 teaspoon flaky sea salt
- Preheat oven to 350 degrees (F). Line an 8x8 baking pan (or loaf pan) with parchment paper and spray parchment lightly with non-stick spray, set aside.
- Melt butter in a medium-sized skillet over medium heat. Continue cooking butter, stirring frequently, until it's a light amber color and smells slightly nutty. Remove from heat at once and cool for a few minutes before whisking in the brown sugar; beat until well combined. Add in the egg, beating until combined. Gently stir in the flour, baking powder, and cinnamon, being sure not to over mix. Fold in the chocolate chips and chopped walnuts.
- Bake for 25-28 minutes, or until the edges are firm and golden and the center is just slightly wobbly. Sprinkle with sea salt. Cool in pan for at least 15 minutes before cutting.
Hi how big are your cups?? Confused on how much butter, flour and sugar I would need
Hi Anon. A cup is 8 ounces. For the butter I use one stick, which is 4 ounces. The sugar and flour are measured in a standard American measuring cup.
240g (or mls in a 250ml measuring cup) flour
240g (or mls in a 250ml measuring cup) firmly packed light brown sugar
2.5g baking powder
The original recipe must be corrected to say 1/4 cup of butter.
The recipe is ok. 1/2 cup of butter is 4oz.
120 g flour or 1 cup or 8 oz
Pls can you suggest an alternate dor eggs …
I’m late but flax egg is good. Flax seed mixed with water
Came across this recipe while wandering on instagram. I’m excited to try it tonight in an 8×8 pan!
Yay! Can’t wait to hear how they turn out, Kaylin 🙂
Can you please share substitute of egg in the recipe. We don’t eat eggs. Thanks
I hope one of your exciting projects is a BOOK! I would buy it for everyone I know!!! Also, I made these today but added toffee bits. Oooomg so good. The edges were crispy but the center were so soft and buttery. Another winner from you!
These are the best! Just delicious – the salt makes the difference. My husband actually prefers them to Brownies – the highest accolade! I’m finding they need 22 minutes at 170C fan oven.
Kayle (The Cooking Actress) says
Oh Ashley I miss you! Just come to Ohio, ok? And bring blondies!
Seriously these look phenomenal-they’re everything I love! And your pictures always make my mouth water!
Hey! This recipe looks absolutely gorgeous and I can’t wait to try it.
I have some brown butter lying on hand. Is it okay if I use that and if so, could you give me a measurement for it?
Hi Aaira. Yes, you can use it, just melt it first (on low heat so it doesn’t burn) and then use amount called for in the recipe.
Karly Campbell says
Well, nuts. Looks like my diet’s going down the drain with this one! These are just too gooey and chocolatey to resist. YUM!
I just made these and my batter is very thick. Also I am not seeing any salt in the recipe…. I spread them in the pan and we’ll see how they come out.
Hi Emily. The batter is very thick. How did they turn out?
I ended up having to “press” them into the pan. They turned out good, but more like a square chocolate chip cookie. The top didnt get crackly like a normal brownie. My husband took them all to work and they were all gone in under an hour. They tasted good either way. I will make them again.
I am glad I saved this to my sweet tooth pinterest board! Last night I made these delicious bars in an 8×8 pan and used the shortest recommended time. They were perfect with a crispy edge and soft and chewy center. My boyfriend and I ate them after 40 minutes out of the oven…with spoons…straight out of the pan…no shame! They are just as tasty the next day also (we didn’t eat the whole pan yesterday!). I have a love for pecans so I might switch from walnuts to pecans next time. Thank you for the recipe!
Awesome! So happy they were a hit 🙂 And I think pecans would be delicious!!!
Big thumbs up . I tried your blondies recipe yesterday and it came out amazing. .. thank you for this amazing recipe..
Gidget the midget from Cali says
Omgosh…made these lovelies today along with some peanut butter cookies because my hungry teen grandson is coming to stay with me for a few days. These were absolutely scrumptious! While I’m a huge fan of cookies bars, these Blondies by far surpassed my expectations of a decadent dessert! GREAT recipe! Thanks for sharing!
Glad you love the recipe! Thanks for letting us know!
I’ve made these and love them. Just wondering if I wanted to make them ahead, how long will they last in a container?
If I doubled this and baked in a 9 by 13 pan how much time should I add to baking?
I made these for Sunday night dessert. OMG between the nutty flavor from the walnuts being toasted and browning the butter, I’m totally on love not to mention the chocolate chips to! Thanks for the great recipe!
Should the butter be measured once it’s melted or in a solid state?
For this recipe what’s the substitute for egg tht is
for vegetarians. Thanks
What’s the substitute for an egg in this recipe for vegetarians .thanks
These tasted amazing! I was craving something sweet and decided to throw these together since I already had all of the ingredients. I was surprised by how easy and fast they were to make. My husband loved them so much that he licked the plate! Great recipe!
Brianna Evans says
Has anybody made these in a 13×9 pan? Would I have to double or 1.5x the recipe and cook them at a different time?
Hi! Which brand of chocolate chunks are you using? Thanks!
Mine turned out perfectly! I would just leave the cinnamon out next time.
Shaann Yeow says
May I know bake with fan force on also for 25 min? Or can be shorter the baking time w fan force?
Awesome recipe! I didn’t really see a wiggle but baked till top was golden and still had a gooey center so it all worked out!
Do I need to melt 1 stick of butter or do I need that much of melted butter? Cause when I melt it, there is less of butter in volume…?
Hi! What kind/brand of chocolate chunks are you using?
I made these at 9:30 at night! I had discovered the recipe via Instagram and just couldn’t stop thinking about them. I had read how swift and easy they were to make so I just did it and OH MY WORD! They are amazing!! I didn’t add walnuts as my 6 year old son doesn’t like nuts and added some white chocolate chunks with some 70% dark chocolate and love the mix of these 2. Thank you so much! NB I baked mine for 20 minutes on fan and they were cooked to fudgy perfection
Hello, I just tried making these and it was a fail I’m sure. I have Cookie dough instead of brownie batter it’s not close to brownie batter at all I followed The recipe to the T I’m not sure where I went Wrong. Please help!
Hi Darae. This is not a brownie recipe. It’s a blondie recipe, which is very similar to cookie bars. So the dough should resemble a thick cookie dough. I hope that helps!
Dayana Flores says
Can we use a diferente kind of salt like coarse sea salt or fine sea salt? I cannot find flaky sea salt anywhere.
Sure! Or just skip it!
Shoug Al-Suwailem says
Hello, can I use coconut sugar instead of light brown? Excited to make it!
vidushi luhariwala says
Substitute for eggs in the recipe?
Stefany Schuett says
Hi Ashley! I have a question. You have different blondie recipes and I wanted to try this one out but I noticed it doesn’t use an extra egg yolk (like your other blondie recipe) and it uses baking powder (which in your other recipes you don’t add).
I just would like to understand why is that.
I love your blog, thanks!
What temperature to use for fan-force oven, and for how long please?
These were great! I left out the walnuts but next time I think I’ll toss in some toasted shredded coconut.
Rachel A says
Yum! These blondies not only taste amazing but also have a great soft, chewy texture. I’m loving the edges! I was a little skeptical about the cinnamon, but it really brings the flavors together. Thank you!
Hello! How can I replace the egg? Would a flax egg work? Thanks 🙂
Amazing recipe! We loved it! I doubled the recipe and baked it in a 9×13 baking pan with dollops of nutella on top swirled into the batter. So good!
HIya! Made this delicious recipe on May 9th. Oh boy were they scrumptious! My husband and I practice OMAD so usually if I bake, I bake after the meal and don’t get to try one until the next day. Your blondies I was able to make before OMAD, after my workout, and because they were quick and easy, we each got to have one as part of our meal! Hoo-rah!
This was super easy and looks delicious- haven’t gotten to try them yet. Is it intended that batter is mixed together in the skillet the butter is melted in? That is how I read the recipe. Thanks for your great ideas!
Came out of the oven looking amazing and looked very much like your picture. However, I did not get that caramel color and textures batter as I transferred all the ingredients to a bowl. I ended up having a cookie dough consistency.
Was I supposed to leave butter in the skillet? I thought I was supposed to put it first into a bowl to cool off and then carry on with the other ingredients.
Thanks for letting me know!
I love this recipe! I usually omit the cinnamon and add vanilla instead. The brown butter technique is solid and the end result is divine. I use this recipe often, it has been a go-to for years, thank you!
Very delicious! Didn’t know blondies before. They were great
