Ingredients:

  • 1/2 cup (100g) granulated sugar
  • 1 tbsp (6g) fresh lemon zest
  • 3/4 cup (170g) unsalted butter, softened
  • 3/4 cup (165g) packed light brown sugar
  • 1 large (50g) egg, room temperature
  • 1 tsp (5ml) vanilla extract
  • 2 tbsp (12g) fresh lemon zest
  • 1 tbsp (15ml) fresh lemon juice
  • 2 1/4 cups (280g) all-purpose flour
  • 1 tsp (3g) cornstarch
  • 1/2 tsp (3g) baking soda
  • 1/4 tsp (1.5g) salt

Instructions:

  1. Combine the granulated sugar and 1 tbsp lemon zest in a small bowl. Use fingertips to rub the zest into the sugar until the mixture is fragrant, moist, and pale yellow.
  2. Beat the softened butter and brown sugar together on medium-high speed until light and fluffy (about 2-3 minutes).
  3. Add the egg, vanilla extract, 2 tbsp lemon zest, and lemon juice to the butter mixture. Mix until fully combined and smooth.
  4. In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet mixture on low speed. Mix only until no streaks of flour remain; do not overmix.
  6. Preheat oven to 350°F (175°C). Scoop rounded tablespoons of dough and roll them into balls.
  7. Roll each ball in the prepared lemon-infused sugar and place on baking sheets lined with parchment paper.
  8. Bake for approximately 10 minutes, removing them while they still look slightly underbaked to ensure a soft center.
