Actually *Perfect* Blondies
Buttery, soft, chewy, loaded with your favorite add-ins, my blondie recipe is perfectly decadent. With hints of butterscotch, vanilla, and caramel, you won’t miss the chocolate. Serve slightly warm, topped with vanilla ice cream and a drizzle of caramel sauce for a truly indulgent experience.
I spent a great deal of time developing this blondie recipe (you can’t imagine how many batches of not-quite-perfect blondies I had to eat, it’s a tough life 😉) and I finally have the perfect version to share. My recipe includes lots of tips and tricks so you’ll get perfectly soft, chewy and buttery results every time. No dry or cakey blondies here! Let’s get right to it.
Blondie Ingredients
We don’t need to cover everything, but let’s chat a moment about some of our key players:
- Butter. Melted butter is the key to a softer, chewier blondie recipe that stays soft and chewy (it’s also a key ingredient in my best chocolate chip cookie recipe, if you’ve tried that you already know what a game changer it is).
- Sugar. A blend of brown and granulated sugar works best here. The higher ratio of brown sugar works well to impart a deep, rich, and subtly caramel-y flavor that makes these irresistible.
- Eggs. An extra egg yolk contributes to the tender, dense texture of the bar.
- Baking powder. Blondies ought to be dense and leaning toward fudgy territory, but just a pinch of baking powder adds a bit of lightness to the bar so it’s not too dense or difficult to chew. Note that the omission of baking soda is intentional, baking soda would create a lighter airier, and more cakey texture that we’re actively trying to avoid.
- Cornstarch helps make the bars tender and chewy.
- Add-ins (use your favorites!). Truth be told, you can add nothing, no nuts, no chocolate, and you’ll still have a darn good cookie bar. But I prefer to dress things up a bit. White chocolate chips and chopped walnuts are my favorite, but swap out the white chocolate for semisweet or a chopped baking bar, swap out the nuts for a different kind of nut or more chocolate, or if you want to toast your nuts before adding them, that works just fine, too!

How to Make Blondies
The blondie batter comes together quickly and easily. No mixer needed, no fancy equipment.
Start by melting your butter. It doesn’t need to cool completely, but if it’s still quite hot when you add the butter you can expect your blondies to be a bit greasier on the bottom after baking and to take longer to bake.
Add the sugars, eggs, yolk, and vanilla. Stir it well, but don’t go crazy. Mixing well can help create shiny/crackly tops, but over-doing it could make the blondies a bit cakier than I personally care for them to be. I never use a mixer for this step.
Add the dry ingredients. Always whisk them together separately (to make sure the baking powder and salt are well-distributed through the batter), then stir them into the batter. Once again, don’t go overboard with the mixing. Any add-ins you’re using get stirred in last.
Bake & enjoy. The very edges will turn lightly golden brown and a toothpick should come out clean. A sprinkling of flaky sea salt while they’re still warm is optional, but strongly encouraged 😉. Let the blondies cool completely before you cut into them, otherwise you may panic that you completely underbaked them (you likely didn’t).
Tips & Variations
- When it comes to sugar, a blend is best. For the brown sugar called for in the recipe, you can just use light brown sugar, but I personally prefer a blend of light and dark brown sugar. I don’t care to use all dark brown, though, as I feel it makes things a bit too rich and butterscotch-y.
- Adjust the add-ins. 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. Feel free to use all walnuts, all chocolate (completely fine to make this recipe nut-free), or swap out some or either of these. A chopped semisweet chocolate bar is quite delicious, in my opinion.
- Pay attention to your pan. A metal pan is best for this recipe and will ensure the quickest and most even baking. If you opt for a glass or ceramic pan, your blondies will almost certainly take longer to bake, and exactly how long will vary. I haven’t tried this blondie recipe in a silicone pan, but am not sure I’d recommend it.
- Brown your butter for a gourmet flavor. Brown 1 cup of butter (you do not need to brown extra to accommodate the lost liquid from browning). You will want to make sure it’s cooled a bit before adding the eggs, so the eggs don’t cook prematurely.
Frequently Asked Questions
Blondies are occasionally referred to as “blonde brownies”. They are made without cocoa powder and without melted chocolate and aspire to a rich, buttery brown-sugar-vanilla flavor rather than a deep chocolate one (so you can expect a higher ratio of brown sugar to granulated here).
White chocolate brownies are closer in nature to brownies than blondies are, while blondies are more similar to chocolate chip cookie bars.
Most often this is due to over-baking. Baking for too long or on too high of a temperature will quickly change the texture from fudgy/borderline gooey to crumbly and dry instead.
Other culprits include accidentally mis-measuring an ingredient, using the wrong kind of flour (you need all-purpose, and please do not use self-rising!), accidentally using baking soda instead of powder, or over-measuring your flour.
First, check your pan. If you used a glass, ceramic, or silicone pan the blondies will take longer to bake, and exactly how much longer can vary greatly depending on the particular material of your pan (some people have needed over 45 minutes to bake!). If you use a smaller pan, even if it’s metal, the blondies will also take longer to bake.
If you substituted or accidentally mis-measured any ingredients, this could also cause this issue.
Wait for the blondies to cool at least mostly before cutting into them, if cut into while warm they’ll look quite underbaked.

Notes
Brown sugar
I like to use half dark and half light brown sugar in this recipe for a perfectly balanced flavor with butterscotch undertones. If you don’t have both, you can use just light brown sugar.Add-ins (nuts & chocolate), and making this recipe nut-free
You can use up to 2 cups of your favorite add-ins, feel free to swap out the white chocolate chips and nuts for your favorite additions (semisweet chocolate chips, pecans, a chopped baking bar, etc.). This recipe can certainly be made nut-free, just swap the nuts for an equal amount of white chocolate chips or your preferred add-in.Pan note
A metal baking pan is recommended. Using a glass, ceramic, silicone, or other material will increase the time needed to bake, sometimes significantly. Please also note that if you opt to use a smaller pan the baking time can be expected to be longer.Storing
Cover tightly (or cut and transfer to an airtight container and store at room temperature for up to 4 days. These blondies may also be sliced, tightly wrapped and frozen for several months.Nutrition

Fantastic!
krista chadwick
Ummm, yum! We substituted 1/2 a cup of the flour for whole wheat, added nuts, chocolate chips, coconut, and chopped maraschino cherries (cuz that is what grandma did)….We were careful not to overcook and these turned out marvelous! Thank you for this perfect recipe!
Norma
This recipe worked out great! I’m a former chocolate brownie fan, but can’t have chocolate anymore. These blondies are so delicious! I used white chips and chopped walnuts and now I have to fight the urge to have another piece every time I pass them on the counter. Thanks for a wonderful recipe!
Kate
These turned out PERFECTLY! I subbed arrowroot flour for cornstarch (was simply out), and added sprinkles to make them “birthday cake” bars…and my family cannot get enough!
JCummins
Hi! I’m wondering if you could use browned butter for this recipe? Would you use the same amount of butter?
Sam
I actually have a browned butter blondie recipe. 🙂
Emily M
Why did mine turn out incredibly dry? I followed the recipe to a T….,
Sam
I’m so sorry to hear that, Emily! The most likely culprits are the blondies being over-baked, or having too much flour in the batter. 🙁
Mamacancook
These are the ULTIMATE blondies!!!!!!!!!!!! I used toasted pecans and Ghirardelli’s white chocolate chips…WOW!!!
HG
Amazing and so easy! I thought they would be a bit greasy from 2 sticks of butter, but they are just perfect. I have made them MANY times.
Sam
Thank you so much for trying my recipe! I’m so happy to hear you enjoyed! 🙂
Lynn
Since my husband can’t eat the milk chocolate we made these and I think we like these even better. Followed recipe to a T. it’s perfect!
Leslie
Great recipe! I’m not sure why blondies fell out of fashion. They are better than brownies! Don’t skimp on the extra egg white to make them chewy. I made mine with all dark brown sugar and it turned out delicious.
Raymond
Thank you for your input Leslie 😊
Amy
I’m going to try these but was going to make them as mini muffins. Any suggestions on oven temp and time? Thanks!
Sam
Hi Amy! The temperature would be the same, but I’m not sure on a bake time. 🙂
Cynthia
So yummy!! I usually have to be in a baking mood, but my middle kid cornered me and asked for Blondies this morning. I was silently booing her. These are pretty awesome. Very easy recipe to follow, too. Thank you!
Carrie
I made this exactly as said and they turned out kinda salty..
Sam
Oh no! I’m so sorry to hear this, Carrie! Did you use salted butter by chance?
Tanya
I can’t wait to try this recipe!
How to store the leftovers, please? How long on can it last at room temperature, in the fridge and freezer?
Sam
Hi Tanya! You can store them at room temperature for 5 days. I would make sure to keep them wrapped tightly so they don’t dry out. 🙂
John G
Since discovering this recipe it’s been on regular rotation! We skip the chips and nuts, but add a good handful of dried cherries, it’s amazing
Taylor
These were absolute perfection. Didn’t have white chocolate so I used a few dark chocolate chips. So delicious.
Sara
Moist and delicious! Cut the recipe in half and used an 8×8 pan. These brownies are a keeper.
Hannah
Wow! Those were good! I had SUCH a sweet tooth craving and no chocolate in the house. Fortunately, this was such a sweet and delightful treat that I didn’t even think of anything else. I did half the batch and served them just after a few minutes of cooling and came out soooooooooooooooooo yummy!
This is a keeper. Thank you for sharing.
