Ingredients

Wet ingredients:

3/4 cup unsalted butter - melted and browned, and cooled
3/4 cup brown sugar
1/4 cup granulated sugar
2 large eggs - at room temperature
1 Tablespoon vanilla

Dry ingredients:

2 ¼ cups all-purpose flour
1/2 teaspoon kosher salt
1 teaspoon baking soda
1 teaspoon cornstarch
1 cup white chocolate chips - plus more for the top
extra sprinkle of kosher salt - after baking

Instructions

How to make brown butter:

Place the butter in a pan on the stove, over medium heat. Let the butter melt, and when it starts sizzling, start stirring with a spatula. Keep the heat at medium, and stir gently, keeping the butter moving in the pan.
After about 5-10 minutes, you should see some brown bits starting to form on the bottom. When you see this, stir for a few seconds longer, and then remove the pan from the heat.
Pour the butter immediately into a bowl. Let the butter cool slightly. I sometimes place it in the fridge for a few minutes. Now you are ready to use it in your cookies!

Make the blondies:

Combine wet ingredients. To a mixing bowl, combine the slightly cooled browned butter and both sugars. Use a hand mixer to cream together. Then add the egg and vanilla and mix again.
3/4 cup unsalted butter, 3/4 cup brown sugar, 1/4 cup granulated sugar, 2 large eggs, 1 Tablespoon vanilla
Add dry ingredients. Add the dry ingredients to the bowl – the flour, salt, baking soda, and corn starch. Mix until just combined.
2 ¼ cups all-purpose flour, 1/2 teaspoon kosher salt, 1 teaspoon baking soda, 1 teaspoon cornstarch
Add white chocolate chips. Add the white chocolate chips to the cookie dough and stir in to the dough with a spatula.
1 cup white chocolate chips
Prepare an 8×8 pan with some parchment paper (makes it easier to lift the blondies out of the pan). Spoon the batter into the pan, evenly distributing it to all corners of the pan. The batter will be thick.
Bake. Bake the blondies at 350 degrees for about 15 minutes, remove the pan, and carefully press extra white chocolate chips into the top and bake for another 8-12 minutes (or until done to your liking). Top with an extra sprinkle of kosher salt.

Cool. Let the blondies sit in the pan for about 10-15 minutes after baking. Then carefully use the parchment paper (handles) to lift the blondies out of the pan. Place them on a cooling rack. Slice.

Notes

What does brown butter do for cookies?

Brown butter takes a regular cookie and makes it gourmet. It creates a nutty aroma and flavor profile that is like no other, especially in a cookie.

What happens when butter is browned?

When the butter melts, water evaporates out of the butter and the butterfat and milk solids separate. The solids sink to the bottom of the pan and eventually begin to brown. The butter then turns into a heavenly rich fat that will transform your cookies.
