Ingredients:
- 1 cup (200g) granulated white sugar
- 2 tablespoons fresh lemon zest
- 2 tablespoons (25g) light brown sugar, packed
- 1/2 cup (113g) unsalted butter, softened
- 1 large egg, room temperature
- 1 large egg yolk
- 1 tablespoon (15ml) fresh lemon juice
- 1 teaspoon vanilla extract
- 2 cups (250g) all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/2 teaspoon fine sea salt
- 1/4 cup (50g) granulated sugar for rolling
Instructions:
- Infuse the sugar. Rub the 2 tablespoons of lemon zest into the 1 cup of granulated sugar and 2 tablespoons of light brown sugar with your fingers. Note: This releases the oils and creates a much more vibrant flavor profile.
- Cream the fats. Add the 1/2 cup of softened butter to the lemon sugar and beat on medium high for 3 minutes until the mixture is pale and light.
- Emulsify the liquids. Mix in the large egg, the extra egg yolk, the 1 tablespoon of lemon juice, and the 1 teaspoon of vanilla extract. Note: Scrape the bowl to ensure no butter streaks remain.
- Whisk dry ingredients. In a separate bowl, stir together the 2 cups of flour, baking soda, baking powder, and sea salt.
- Combine the dough. Gradually add the dry ingredients to the wet mixture on low speed until just combined and no white streaks remain. Note: Over mixing here will make the cookies tough instead of chewy.
- Chill the dough. Cover and refrigerate for at least 30 minutes. Note: This prevents the cookies from spreading into flat pancakes in the oven.
- Preheat and prep. Set your oven to 350°F (180°C) and line two baking sheets with parchment paper.
- Roll the dough. Scoop 1 tablespoon portions of dough, roll into balls, and coat them in the 1/4 cup of rolling sugar until fully covered and sparkling.
- Bake the cookies. Place balls 2 inches apart and bake for 9 to 11 minutes until the edges are just barely set and the tops look slightly cracked.
- Cool and set. Let the cookies rest on the hot pan for 5 minutes before moving them to a wire rack. Note: This allows the center to finish setting through carryover heat.
