Looking for the best blondie recipe? These rich, buttery blondies have chewy centers, crisp golden edges, and plenty of chocolate chips in every bite.
Blondies are rich, buttery bar cookies with a rich caramel flavor and chewy texture. Often described as the vanilla version of a brownie, they’re made with brown sugar instead of cocoa and studded with chocolate chips (plus optional pecans for crunch).
I’ve baked countless batches of blondies over the years, but I always come back to this recipe. they have the perfect balance of crisp edges, chewy centers, and gooey pockets of melted chocolate. It’s the kind of foolproof recipe you’ll bake again and again.
Perfect for bake sales, potlucks, holiday cookie trays, lunch boxes, or after-school treats, these blondies also freeze beautifully, making them an easy make-ahead dessert.
“Best blondie recipe I have made and my go-to for a quick and delicious dessert.”
Blondie Ingredients
- Melted Butter: Provides a rich, creamy base for the batter. Melted butter creates a denser, chewier blondie. You can also use browned butter for a nuttier flavor or swap it for coconut oil or non-dairy butter alternative if you need to make this without any dairy.
- Brown Sugar & Granulated Sugar: Brown sugar adds moisture and a deep, caramel-like flavor, while granulated sugar sweetens and gives the blondies crisp edges and soft center. (Be sure to pack the brown sugar tightly.)
- Egg & Vanilla Extract: The egg binds everything together, while vanilla adds warm, aromatic flavor.
- All-Purpose Flour: Provides structure for the blondies. For the most accurate measurement, use the spoon-and-level method: spoon the flour into your measuring cup and level it off with a straight edge—don’t scoop directly from the bag, which can pack in too much flour.
- Semisweet Chocolate Chips & Chopped Pecans: These mix-ins add texture and flavor—melty chocolate in every bite and a subtle crunch from the pecans.

How to Make Blondies
Step 1: Mix the butter and sugars. Beat the melted butter with both sugars until the mixture looks smooth—this is what helps create that shiny, crackly top later on.
Step 2: Add the egg and vanilla. Beat until the batter looks smooth and cohesive.
Step 3: Mix in the dry ingredients. Add the flour and salt on low speed, stopping the moment you no longer see dry streaks. This is the step where it’s easiest to overdo it; extra mixing here develops more gluten and pushes the texture toward tough or cakey instead of dense and chewy.
Step 4: Fold in the chocolate chips and nuts. The batter will be quite thick at this point — that’s normal. If you’re skipping the nuts, a few extra chocolate chips in their place works well.
Step 5: Spread into the pan and bake. Transfer the batter to a greased pan and spread evenly. Bake until the top looks set and lightly golden, with edges just starting to darken. The center may still look a little soft—that’s exactly what you want
Step 7: Cool, then slice. Using the parchment overhang, lift the blondie brownies from the pan and transfer it to a cutting board. Cut into squares and serve warm or room temperature. The bars will keep nicely for a few days stored in an airtight container at room temperature; freeze for longer storage.
Pro Tips And blondie Variations
- Swap the mix-ins: Swap all or half the chocolate chips with white chocolate chips, change the nuts or leave them out, or even add some dried cranberries. Just keep the amount of mix-ins you add to 1¼ cups.
- Line your pan with parchment paper: It makes removing the blondies a breeze and ensures cleaner slices. Be sure to leave an overhang on two sides so you can lift the whole slab out of the pan once cooled.
- Don’t be tempted to add baking powder or baking soda. This recipe is designed to bake up dense and chewy with crisp edges. Adding a leavener will give the blondies a lighter, more cake-like texture.
- Don’t overbake. It’s better to slightly underbake blondies than overbake them. Remove them from the oven as soon as the center is set; they’ll continue to cook from the residual heat as they cool.
- Want to double the recipe? This blondie recipe works great doubled and baked in a 9 x 13 pan. You may need to add a few minutes to the bake time.

Blondies
Ingredients
- ½ cup (1 stick) 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)
Instructions
- Preheat the oven to 350°F (175°C). Line an 8-inch (20-cm) square baking pan with an 8 x 11-inch (20 x 28-cm) piece of parchment paper, leaving a 2-inch (5-cm) 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).
- 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.
- 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.

Love this recipe and will make it often in our home. Perfect texture, crisp, chewy and if served warm with ice cream, it just melts down int to crevices. You won’t be disappointed with this recipe!
I tried this simply because it had the best rating for blondies and it did not disappoint! After reading the reviews I opted for an 8×8 pan and added 1/2 tsp of making powder. My pan made 9 brownies and my husband has eaten 4 in two hours! Thanks ❤️
Jenn, I just made a double batch to send to two neighbors as a thank you. They came very thin and I thought I forgot the baking powder and/or soda. Upon reviewing the recipe again, I see there is none. Can you help me understand what went wrong? Is the recipe correct? Thank you!
Hi Mary, You didn’t do anything wrong. There is intentionally no baking soda or baking powder in this recipe. (These are more like bars/brownies and don’t rise very much.) Although I would check to be sure you used the correct size pan. Hope that clarifies!
Thank you, Jenn! You’re absolutely right, my pans were not the right size so I went with one for a double batch and that’s why they turned out thinner than normal. Also, the taste is incredible and the neighbor loved them. I appreciate your reply and expertise. I always have confidence as a novice baker using your recipes 🙂
I’ve made these on 3 different occasions and the result is perfection! I follow the recipe as written — and truth be told, I’ve taken up baking just this year, so I’m still learning. Jenn’s instructions & pictures make it very easy to follow. These blondies are gobbled-up quickly by friends and family every single time!! 👍⭐
I have a question. In the recipe it calls for a square 8” pan. The photograph looks like a rectangular Pyrex dish. Which is correct?
Also I have been told when baking in Pyrex to lower the temperature by 25’. Do you agree?
I am looking forward to a response as I want to try this recipe.
I am also looking forward to receiving your new cookbook in the fall.
Thanks Jen,

Hi Rena, it must be the picture, but that is a square pan. And regarding using glass, I’d keep the temperature the same. Just keep an eye on it and reduce the heat by 25°F if it looks like it’s starting to brown around the edges. Enjoy!
These were incredible! Definitely will be making them again.
It’s a nice recipe but I did expect better. The blondies are way too thin. Pan size needs to be reduced, or recipe needs to be doubled. Reduce baking time if you’re after a fudgey blondie. If you’re more than a novice baker, I probably wouldn’t recommend this recipe.
Best blonde brownie recipe I have made. I didn’t have pecans so substituted walnuts. I followed the recipe exactly and baked for 25 minutes. Delicious! 😋
Perfecto. Changes made: Doubled recipe for 9 x 13 pan. Browned the butter and let it cool. Added 1tsp baking powder. Baked for 38 min until toothpick came out slightly moist. This recipe is a winner. Thank you.
Prior to seeing your review, I did the exact same thing! In addition to doubling the recipe, browning the butter and adding 1tsp of baking powder, I also toasted the pecans and added about 2T more flour because the batter seemed too wet/oily. I think next time I’d bump it up to 1/4c. extra flour. And the baking powder if a necessity IMO. Delish!
If I need to double the recipe, what size baking pan and baking time do you recommend? Thanks!
Hi Negin, I’d recommend a 9 x 13-inch pan. Baking time may be a touch longer but keep a close eye on it. Hope you enjoy!
