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.
