The Perfect Three-Sugar Sugar Cookie

• 1 1/4 cups unsalted butter
• 1/4 cup granulated sugar
• 1/2 cup demerara sugar (or light brown sugar)
• 1 3/4 cups dark brown sugar
• 2 large eggs
• 2 1/4 teaspoons vanilla extract
• 1 3/4 cups all-purpose flour
• 1 cup 2 tbsp. bread flour
• 1/2 teaspoon baking soda
• 3/4 teaspoon baking powder
• 1 1/2 teaspoons vanilla salt, or kosher salt

1. Preheat the oven to 350 degrees. In a large bowl, cream together the butter and sugars on medium speed until fluffy, about 2 minutes. Add the eggs one at a time, and beat well after each addition.
2. Add the vanilla extract, the flours, the baking soda, baking powder, and salt. On low speed, beat the mixture until the dry ingredients are well-incorporated, about 1 minute.
3. Line a baking sheet with parchment paper, or a Silpat. Scoop a heaping tablespoon of dough and roll it until it forms a sphere between your palms. Place the dough on the baking sheet (8 cookies per sheet), giving them room to spread. Dust the tops of each ball of dough with a little demerara sugar, and a tiny bit of fleur de sel or vanilla salt.
4. Bake in a 350 degree oven on the middle rack for 12-15 minutes. (Do not bake these on the bottom rack in the oven-the high proportion of brown sugar will cause the bottoms to darken too much.) At this time, the cookies should have taken on a golden brown color all around the edge, but still look very soft in the center-like hot cookie dough. Remove the tray from the oven, and allow the cookies to cool directly on the tray for 10 minutes before eating.
