Instructions

• Preheat the oven to 350 degrees F. Line the bottom of an 8×8 baking dish with parchment paper.

• Make the brown butter: In a small pan set over medium heat, melt the butter and cook until it turns brown and smells nutty, about 5 minutes. Try not to walk away from the butter, as it can go from brown to burned very quickly. Pour the brown butter into a large mixing bowl and let it cool slightly.

• Whisk together the flour, baking powder, and ¾ teaspoons of the sea salt to combine.

• Add both sugars to the brown butter and mix on medium speed with a hand mixer until well combined, about 2 minutes.

• Add the eggs and beat for another 2 minutes, until the mixture has lightened in color.

• With the mixer on low, slowly add the flour mixture, mix just until the flour is fully mixed in.

• Pour the mixture into the prepared pan and sprinkle with remaining sea salt.
