Blondie Recipe with Chocolate Chips & Pecans - Once Upon a Chef (1)

Part cookie, part brownie—who doesn’t love blondies? The best part is that they’re ridiculously easy to make. They have less ingredients than chocolate chip cookies (plus you don’t have to roll the dough into balls) and they’re easier than my go-to brownie recipe because there’s no chocolate to melt. This version made with chocolate chips and pecans is my all-time favorite.

Chocolate Chip Pecan Blondie Recipe

Metric Cup Measures

By Jenn Segal

Part cookie, part brownie — who doesn’t love blondies?

Servings: Makes 16 squares


  • 1 stick (½ cup) unsalted butter, melted
  • ½ cup packed dark brown sugar
  • ⅓ cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour, spooned into measuring cup and leveled-off
  • ½ teaspoon salt
  • ¾ cup semisweet chocolate chips
  • ½ cup chopped pecans (optional)


  1. Preheat the oven to 350°F degrees. Line an 8-inch square baking pan with an 8x11-inch piece of parchment paper, leaving a 2-inch overhang on two sides. You'll have to create seams in the corners and along the edges of the pan to get it to stay put (you can always add a few dots of butter underneath if necessary).
  2. In a large bowl of an electric mixer, beat the melted butter with the brown sugar and granulated sugar until well combined, about 2 minutes. Beat in the egg and vanilla. On low speed, mix in the flour and salt until just blended. Stir in the chocolate chips and nuts. Transfer the batter to the prepared pan and spread evenly with a rubber spatula.
  3. Bake for 25 to 30 minutes, until the top is set and lightly golden. Set the pan on a wire rack to cool. Using the parchment overhang, lift the blondie "cake" from the pan and transfer it to a cutting board; cut into 16 squares. Store the blondies in an airtight container at room temperature or freeze for longer storage.
  4. Freezer-Friendly Instructions: The blondies can be frozen for up to 3 months. After they are completely cooled, double-wrap them securely with aluminum foil or plastic freezer wrap. Thaw overnight on the countertop before serving.

  • I would like to try these with Browned Butter. Or will it be fine as written since you suggest to add extra flour if wanting them slightly less buttery? Or do you recommending adding an extra tablespoon of butter before melting/browning to make up for the lose of liquid?
    I am a long time fan and appreciate that I can choose any recipe and feel confident it will be great the first time! Thanks.

  • This sleeper of a recipe had it’s debut last night The ease of getting the blondies into the oven totally belie the fact that they are special. Truly special. Classic chocolate chip cookie flavor in a texture that is just as Jenn said…like a brownie! Every bite had my brain mis-fire deciding if this was a cookie or a brownie. And that part was fun too! Any time I’ve made a blondie recipe I typically bake at the longer end of the time given, and did go the full 30 minutes. Golden color on the top crust, and yet totally soft and chewy. LOVED these.

I substituted light brown sugar for the dark and walnuts for the pecans and it was absolutely delicious. This will be a go to recipe from now on. So easy to make yet decadently delicious! Thanks so much for all of your fabulous recipes. Happy holidays to you and your family

    • Reply
    • Hi Sarah, Unfortunately I’ve never tried those so I can’t say for sure, but there’s no reason you couldn’t add white chocolate chips and dried cranberries to these instead of the nuts and chocolate chips. You could also add a teaspoon of orange zest. It looks like those bars also have a cream cheese frosting, so I would add that as well. Please LMK how they turn out if you try them!

  • I love this recipe so much- it’s one of my go-to’s! Quick question- I have a lot of cherries and wanting to add cherries to these bars to make cherry/choc chip blondies. Would you recommend I adjust any of the ingredients with the addition of the cherries?

    • — Meaghan on July 26, 2023
    • Reply
    • So glad you like it! Unfortunately, I don’t think adding cherries would work here. They would add moisture to the mix throwing off the wet and dry ratios. Also, they are tart which would you require to change the amount of sugar. Sorry!

  • Dairy free here, so I subbed Miyoko vegan butter (cashew based) for the butter. Otherwise I doubled everything and used a 9×13 glass bake dish as recommended. Delicious! They came out brownie-like, not cookie-like.

    I did reduce the chocolate chips. Instead of 3/4 cup per recipe I used 1/2 cup.

Since I had them in my cupboard I used equal parts mini cacao, white chocolate & dark chocolate chips to mix it up and of course pecans. May want to add some raisins or coconut next time…

  • Bottom line: this is a recipe I am adding to my favorites. I needed to attend two gatherings last weekend, so I made two “blondies” recipes, to test them out. The ingredients were similar in type, just differing amounts. This one was far superior in flavor and texture.

  • I’ve made this blondie recipe twice. Both times I substituted 1/4 white chocolate, 1/4 butterscotch, and 1/4 milk chocolate chips for the 3/4 cup semi-sweet chips. I loved the flavor the first time I made, but in my oven 30 min was not enough to set the center and even in increments I ended up burning the top. The second time I cooked at 300 degrees for 55 min and it came out perfectly-lightly browned, slightly glossy on top like a good brownie and a bit chewy. Delicious.

  • This recipe needs to be doubled to make a brownie of “standard” thickness. The recipe as only makes a brownie about 1/4 inch high. Please fix your recipe-we don’t need more poor recipes on the internet.

    • I glossed over the detail that the pan used is to be an 8-inch square because my eyes fixed on the “8X11-inch parchment paper” and I mistakenly assumed I needed a larger pan. The blondies were thin, and I think you may also have made the same error I did by using a 9×13” pan! Still delicious though, but next time I’ll use my smaller dish to achieve that chewier blonde texture! Thanks for another outstanding recipe Jenn!

  • I just made these and they are delicious and so easy to make BUT I overcooked mine. Silly me. At 25 minutes, the center didn’t seem to be set so I let them go an additional 5 minutes which was a mistake. My oven is accurate so I am suggesting a cook time of 25 minutes. These are great with vanilla ice cream. BTW Jenn, thank you for all these wonderful recipes and the way that you present them.

  • I made these Blondies for Christmas this year. Everyone loved them and the only thing different I did, was substitute the chocolate chips and nuts for a bag of heath bar chips. (Wanted the texture of nuts without actual nuts) The 8×8 size for desserts allows me to have a larger variety, without so much to eat. Love your small dessert recipes!

  • I tried baking these recently and they were burnt!!😭 Has anybody had any success with modifying the baking temperature and/or time? Maybe I mixed the batter for too long, any suggestions on how long to mix it for? Also, they didn’t really rise either, they just looked more like regular cookies instead of a traditional blondie. Should I use baking powder to help it rise?

    • Hi Mercedes, I’m sorry you had a problem with these burning! If you make them again, I’d cut the baking time back by a few minutes (and I don’t think it had anything to do with how long you mixed the batter). Also, there is intentionally no baking soda or baking powder in this recipe. (These are more like bars/brownies and don’t rise very much.)

  • I love how it was quick and easy to make. I was craving something sweet but didn’t want to go through a laundry list of ingredients and steps. I also didn’t find this sweet which is kind of nice. I ended up using 1/2 c of chocolate and even that was a lot. The batch does appear very small. I used an 8×11 as that’s all I had on hand. It filled about half the pan and I shaped it into a square otherwise it would’ve been ridiculously thin if I filled the whole pan. Only thing I didn’t like was that the bottom of my blondies were very greasy and almost seemed undercooked even though I left it in for the recommended time.

  • DO NOT do this recipe as written. Either double the batch or make cookies. Absolutely no liquidity to the batter, unspreadable in the pan, and didn’t even come close filling an 8×8 in a thin layer. Not sure how this got so many positive reviews—must be paid for by the website.
