Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (227g) unsalted butter, softened
  • ¾ cup (150g) granulated sugar
  • ¾ cup (165g) packed brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • ½ teaspoon mint extract
  • A few drops green gel food coloring
  • 1 ½ cups (270g) semi-sweet chocolate chips

Instructions

  1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a medium bowl, whisk together all-purpose flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened unsalted butter, granulated sugar, and brown sugar with an electric mixer on medium speed until light and fluffy, about 3 minutes.
  4. Beat in eggs, vanilla extract, and mint extract until smooth.
  5. Scoop out about one-third of the dough into a separate bowl. Add a few drops of green gel food coloring and gently mix until evenly colored.
  6. Fold the green dough gently into the plain dough to create a marbled swirl effect without fully blending.
  7. Fold in semi-sweet chocolate chips evenly through the swirled dough.
  8. Using a cookie scoop or tablespoon, drop rounded spoonfuls about 2 inches apart onto prepared baking sheets.
  9. Bake for 10–12 minutes, or until edges are golden and centers look set but still soft. Watch closely to avoid overbaking.
  10. Let cookies cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Do not overmix the dough after adding flour to avoid tough cookies. Soften butter properly (not melted) for best creaming results. Fold green dough gently to maintain swirl effect. Watch baking time closely to prevent overbaking. Cookies continue to cook slightly on the baking sheet after removal from oven. For softer cookies, remove when centers look just set. Dough can be refrigerated up to 48 hours before baking. Freeze baked cookies up to 3 months.
