Ingredients:

  • 1 cup (225g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 large egg (50g)
  • 2 tsp (10ml) pure vanilla extract
  • 2 ¼ cups (280g) all-purpose flour
  • 2 tbsp (16g) cornstarch
  • ½ tsp (3g) baking soda
  • ¼ tsp (1.5g) salt
  • ¼ cup (50g) granulated sugar (for rolling)

Instructions:

  1. Beat the softened butter and 1 cup of sugar together on medium-high speed until the mixture is pale and fluffy (about 2-3 minutes).
  2. Add the egg and vanilla extract, beating until fully incorporated and smooth.
  3. In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt.
  4. Gradually add the dry ingredients to the wet mixture on low speed, mixing only until the last streak of flour disappears.
  5. Scoop 1 tablespoon of dough and roll it between your palms into a 1-inch ball.
  6. Roll the ball in the remaining granulated sugar until evenly coated.
  7. Place balls 2 inches apart on a lined baking sheet.
  8. Bake at 350°F (175°C) for 8-10 minutes. Remove the cookies when the edges are barely set and the centers still look slightly underbaked.
