  • In a large bowl, whisk butter and sugars until smooth. Whisk in egg and vanilla. Add flour and salt; mix just until moistened (do not overmix). Fold in 1/2 cup each chocolate chips and walnuts. Transfer batter to prepared pan; smooth top. Sprinkle with remaining chocolate chips and walnuts.

  • Bake until top is golden brown and a toothpick inserted into the center comes out clean, 40 to 45 minutes. Set pan on a wire rack, and let cool completely. Using parchment overhang, lift cake from pan and transfer to a cutting board; cut into 16 squares.

Cook's Notes

For the neatest pieces, cool the blondie cake completely before slicing. Then, using a serrated knife, cut with a sawing motion.

Yum! I love that this recipe has the right amount of salt to offset the sweet. Delicious.

I made this as written and they not only looked exactly like the picture, but they were very good! I may try some different flavor combinations next time with the chips and nuts.

Seriously? OMG! no joke when I say melt in your mouth good. Even when eat these cold they literally make me all warm and fuzzy inside but they go perfect with your morning coffee too...nvm the biscotti lol BUT I'm glad I read the reviews first because 30 min bake time was already starting to become over baked. I recommend at least doing the toothpick method at 30 min to be safe because it varies depending on how efficient your oven is. Thank you Martha.

Made this recipe dozens of times and everyone loves them. However, make sure to cut the cook time down to 30-35 minutes. At 40-45 minutes, they are overcooked and hard.

After 40 minutes my blondies were brick hard. Not sure why but I will stop earlier next time.

These are absolutely beautiful. I don't digest wheat, so changed up the flour to a gluten-free mixture, and they still turned out really well. [If you do this, ensure the egg is large as the mixture will be lacking the protein otherwise lent by the gluten. (Using two small eggs works well, too)]. I've also made these with regular flour for my brother and they disappeared in a day so I'm guessing that works well too :) Delicious!!

This is one of my favourite cake/dessert recipes ever! It is buttery, caramely and toasty (I often think it tastes like "golden", which is silly but so true). I have seen many suggestions on the comments for altering the measure/type of chocolate chips and nuts, and I sometimes do a different one: I just skip the chocolate chips altogether and keep the same amount of walnuts or even increase it a bit. I have also tried it with hazelnuts and it works great too =)

I agree with CaliDog to reduce the nuts and chocolate chips to 1/2 cup rather than 1 cup each. These are delicious. Will definitely make them again. :-)

This is the best blondie recipe. The only change I make is to use 1/2 cup each of the chip and nuts in the batter, but only 1/4 cup each to top the batter.

LOVE these bars! They were a huge hit with my husband and his family. I took out the walnuts (he's not a fan) and threw in some coconut which made the bars extra moist. I also used the peanut butter-choc chips instead. I also cooked for a few minutes less. Just kept an eye on them. So easy and delicious!

I agree the cooking time was too long. I made mine in one of those "on TV" Brownie Pans and it took only 24 mins. I missed the shiny crackly top and chewy texture that I rate excellent brownies on, but they were good. I subbed pecans for the walnuts. Will make again.

These were good, but I think the baking time was too long. Mine were finished baking after like 25 minutes or so. SO BE CAREFUL when baking. However, great recipe, I cant wait to do it again.

YUM. These were delicious! You get the brownie texture with a chcolate chip cookie taste. I doubled the recipe but only used 1 1/2 C of chocolate chips. Next time I will use the full amount. They were good at room temperature, but they would be even better served warm with vanilla ice cream. Also, even with the doubled recipe, they were finished baking around 28 minutes. I will definitely make these again.

This is the best blondie recipe I have found. I doubled the recipe but still only had enough batter to use a 9-inch square baking pan filled to regular brownie thickness. Cooking time of 35 minutes was perfect.

I agree with MEgs91581. These are good but definitely have too much chocolate in them. I plan on only using half of the choclate (or maybe even less) next time. Or maybe substitute macadamia nuts for the walnuts and white chocolate chips for the chocolate?

I have made these time and time again and they are always a hit. It's the delicious taste of a chocolate chip cookie with the texture of a chewy brownie. What makes these even better is adding butterscotch chips along with the chocolate chips. The butterscotch just makes them even better.

I would love to bring something like this at our next "food day"/potluck at work or church; however, the quantity of ingredients here is only for an 8-inch square pan. I would love to see a recipe like this converted for a 9 x 13 inch pan instead... more to share that way?! I unfortunately find this is the case with many yummy sounding recipes... they're frequently for such a small yield. :o(

These are delicious; it's hard to eat just one. I read all the comments, so I cut the salt to 1/2 tsp as I use salted butter, baked the in a glass 7x11 pan for 35 minutes, and they were perfect! These will be a regular at our house, and at work. I too will try them with toasted filberts, and perhaps skip the sprinkling of CC on top, rather melt them and then drizzle the melted chocolate over top after the squares have cooled.

These are so good that friends continually ask me to make them. These are officially my gift item to folks now. But I add something that makes them even better! Butterscotch chips! And brown sugar dusted on the bottom of the pan before I pour the batter and then on top of the batter. I am about to make some now! Enjoy!

I have better luck making these using bread flour. The higher gluten gives them a chewiness and lift that pleases my palate!

Not great. The flavor is not really distinctive - a little buttery, a little caramely, but nothing that would convince me to make these again.

These were very easy. My 15 year old son and I made them together, and doubled the recipe. We made them in a 9x13 inch pan, and they were perfect. In fact, in a house full of teens running in and out, they were gone the next day.

I knew I had to make them as soon as I saw the recipe yesterday. They turned out really well - though next time I will bake for slightly less time. I love the 8x8 size too - much better than having a huge batch. I will make these again (and again and again...) !!

I have not made these but I will try :) I always underbake!! I like mine a bit chewy :) I don't use salt in any of my cookies - if I do it is a pinch. I don't like salt in my cookies unless it comes from the butter ( I like to use un-salted) or the nuts..... Thanks for the helpful hints

Hello. Can anyone tell me how much a "stick of butter" weighs? We do not use this term in Australia. I wanted to check becasue I think your tablespoon measures are smaller than ours also. Thank you !

Thought they were great - made two batches first too dark even at 40 minutes. Second batch took out at 35 minutes and much better. Family liked them. I've had better. Don't know if I'll make again.

I thought these were salty! I think the amount of salt should be cut in half. They also only took about 30 minutes to bake (I did use a dark pan and that could be why). I thought they were ok--but wouldn't make them again.
