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

Tiffany
Thank you in advance for the recipe! Just popped these in the oven; I followed the recipe to a T. The batter was so consistent and smooth and they look like they will come out perfect!
I picked this recipe out of at least 30 others I scanned on the web for the most delicious sounding dessert bar!
Sam
Thank you for choosing my blondie recipe, Tiffany! I appreciate it and hope you loved them! ๐
Karen
Best Blondie recipe I’ve found after trying four others. I use Heath Bar Brickle and chocolate chips with the walnuts. Butterscotch chips would probably work as well. The extra butter and egg yolk make the difference.
Sam
I am so happy to hear you enjoyed the blondies, Karen!! And I LOVE the sound of your additions, YUM! Thank you so much for commenting! ๐
Lori Gaspar
OMG these are wickedly good! I had a craving for S’mores so I took the base recipe and added 1 package chocolate chips, half bag of mini marshmallows and 9 graham crackers broken into pieces. Baked in 8 x12 pan for 28 minutes. Still slightly gooey and absolutely delicious!!!!! I would recommend a 9 x13 pan next time as the bars were a little thick.
Sam
YUM I love the sound of your additions! So glad to hear you enjoyed the blondies, Lori!! ๐
Christine
Did you mix the marshmallows and graham cracker into the batter or put them on top?
Alex
Hi there! I ran out of vanilla extract yesterday. Do I need to use it with these? I have everything else!
Sam
Hi Alex! You can skip the vanilla extract if you don’t have it. The blondies won’t have nearly as much flavor, but they will still turn out. ๐

Rana
I planning to try this recipe but I want to make half the ingredient. Should I use the 1 egg yolk full or beat it and use half of it?
Sam
You can probably get away with using the full yolk but personally I would beat it and use half of it. Enjoy!

This morning my daughter came into the kitchen and said โyou canโt live here anymore devil woman!โ

Hello! Can I use self rising flour instead of all purpose?? If so could you please tell me what measurements to use?
Sam
Hi Karla! I don’t know how it will turn out in this recipe. I would try to stick to all purpose flour to get the proper texture. ๐
Carmela A.
I just made a batch today and they were so good! I added cashews and chocolate chunks instead. I will probably add less sugar next time to fit my preference. But it was so moist and buttery!!!! Thank you for sharing your recipe!
Sam
I am so glad you enjoyed the blondies, Carmela! ๐
Cragz
Made these today, taste great just like the blondies found in the Ben and Jerryโs Blondies core which was what I was after.
Definitely a must have desert tastes better than actual brownies.
Thank you so much…
Sam
Yay! So glad to hear you enjoyed the blondies, thank you so much for commenting! ๐

Sam
Hi Teha! I think that would work fine. ๐

I made a double batch, one with chocolate chips and the other with white chips and craisins. They both came out great! Not sure what the corn starch does but it works. Thanks for sharing your recipe!
Sam
I’m so glad to hear you enjoyed the blondies, Cathy!
Gitu
Hi I just made these. The only thing I didnโt add is the cornstarch cause I didnโt have any. The blondies taste great but is quite cakey. Is it cause the omitted the cornstarch? Thanks
Sam
I am so glad you enjoyed the blondies. The cornstarch will definitely help with the texture here. ๐
