Preparation
- Step 1
Heat oven to 350 degrees and butter and line a 9-by-9-inch baking dish with parchment paper.
- Step 2
Melt the butter in a saucepan over medium heat. Cook butter, occasionally scraping the bottom and sides of the pan with a rubber spatula, until it turns deep golden brown and smells nutty. Don’t walk away from the pan during this process. The butter can go from brown and nutty to acrid and burnt in mere moments. Transfer the butter and all the brown bits from the pan to a large heat-safe bowl to cool slightly.
- Step 3
When the butter is cool (but still melted), add sugar, vanilla extract and salt. Whisk until smooth. Add the eggs and mix until well combined.
- Step 4
Fold in the flour and baking powder along with any mix-ins until well combined and no streaks of flour remain in the batter.
- Step 5
Pour batter into prepared pan, smooth the top, and sprinkle with flaky salt, if desired. Bake the blondies until set and slightly puffy, 20 to 27 minutes. For gooey blondies, err on the short side of the baking time. Cool before slicing.
- For other add-ins, try 1 cup chopped white or milk chocolate; about 1 cup toasted, chopped nuts; ½ cup toasted unsweetened shredded coconut; about ½ cup dried whole cherries or apricots, chopped; ¼ cup crumbled halva; 2 tablespoons bourbon or rum, or 1 tablespoon espresso powder, mixed in with butter and sugar; or a sprinkle of cinnamon or cardamom, mixed in with the butter and sugar. You can also swirl 2 to 4 tablespoons Nutella, peanut butter or tahini into the top of the batter before baking.

This came together really easily -- I'll never be afraid of making brown butter again! I made a 1.5 sized recipe, to fit my 9x12 pan, but aside from adjusting the cooking time, no other changes. I do suggest a change to the process. Make the brown butter first, then prep the pan, get the other ingredients in order, and pre-heat the oven. By the time the oven is hot, the butter will be cool enough to proceed.
I have made these twice now: once as written and once with the changes recommended in another comment. I prefer the version with the changes as they are lighter and less sweet, but still delicious. Thanks for the recommendation ! Change: 3/4 cup butter and 1 1/4 cup sugar.
I'm a gluten free baker and find that blondies turn out much better if you add some ground almonds/ almond flour to the gf flour mix. It given the blondies a beautiful texture! With this recipe I would use 1 1/4 cups gf flour & 1/2 cup almond flour.
I have made these twice. The first time I made it as written and they were way too greasy although on day two they had firmed up and were better. I just made a 1.5 times batch (with some modifications to proportions) to use in a 9 x 13 pan and they are so much better. Here’s what I did: 1 1/4 c butter, 2 c brown sugar, 1 T vanilla, 1 1/2 t salt, 3 eggs, 3 c flour, 3/4 t baking powder. Added in about 3 c combined white chocolate chips and butterscotch chips. Baked 27 min. Amazing!
Following others notes: I browned the butter (3/4 C.), removed from heat, stirred in brown sugar (1-1/4C light brown + 2T molasses as that is what I had on hand). The sugar helped cool the butter as others noted. Then I followed the remainder of recipe. Easy. Quick. Tasty!
These are amazing. The first and second time I made them for my little sister (11) so I added chopped bittersweet chocolate and a Hershey’s cookies and cream bar. The kids at her school were so obsessed I had to make them twice. The first time I took them out of the oven a little early so make sure you really let the top brown. Now, I’m making them for myself with chopped dates, halva, and some dollops of arequipe (colombian dulce de leche) on top. Next time, instead of mixing the halva in the batter I would sprinkle it over the top because I think it just disolved and made the batter thicker.
