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

Marlene
Do these have a strong vanilla flavor?
Sam
Hi Marlene! They do have a buttery, vanilla flavor. I would not say it is overwhelming. Think of a chocolate chip cookie without the chocolate chips. 🙂
Haylie
The flavor is/was amazing, I found this “batter” to be thick almost like a cookie dough, I reread the recipe 3 times after I got the final product, is this how they’re supposed to be? Or did I do something wrong? I had to bake them for 45 minutes also, they were so doughy, I put them in a 9×13, but maybe I should’ve tried a jelly roll pan?
Sam
Hi Haylie! The batter is a thick dough, like a cookie dough. It sounds like your oven temperature may be off. I bake them in just a regular 9 x 13. I am glad you still enjoyed the flavor. 🙂
Laurie Lewis
Found your website when I googled a recipe for blondies. I am sooo glad I found the recipe, and site. They are hands down one of the best things I’ve made. Your are 100% right when you call it Best Blondie Recipe. I added pecans and toffee bits to mine and my husband couldn’t get enough of them! So far I’ve tried a few other of your recipes and have been so happy with the results. I can’t wait to try more!
Sam
I am so glad you have enjoyed everything Laurie! I hope you continue to love everything you try! 🙂
Kendra
Is there anything you can use to substitute cornstarch? Craving something sweet and these sound amazing! Have everything but cornstarch 🙁
Sam
Hi Kendra! You can use flour, but they may not be as soft/chewy as if you were to use cornstarch. 🙂
Mgt
If you are in UK, cornflour is the substitute for cornstarch.
Mary Kay
YUMMMMM! Great Recipe! I used macadamia nuts and white chocolate chips and they turned out really good. Thanks for the recipe!!
Sam
I’m so glad to hear you enjoyed, Mary Kay! Thank you for commenting!
Reham Greene
Sounds delicious! Do you think I can make this and add a cheese cake swirl?
Sam
Sure I think that would be delicious! Enjoy 🙂
Natalie
With your experience you would know better than I would- Would it taste weird to add milk or semi sweet chips as well?
Sam
Hi, Natalie. I think those additions would be fine. 🙂
Coralie
Love these! Made a batch yesterday added white chocolate and biscoff spread 😀
Found the mix a little thick to swirl in the spreads but will melt them next time which should create a mixer pattern.
Now baking again with extra toppings for everyone in the office – top brownie points 😉
Thanks for the recipe!
Sam
I’m so happy to hear you enjoyed, and the addition of the spreads sounds SOO good! Thank you for commenting, Coralie!!

Can I use a 9×9 pan for this recipe?
Sam
Yes that would work just fine, they just need to bake longer. 🙂
