Ingredients

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

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch pan or line it with parchment paper.
  2. In a large bowl, whisk together the flour, baking soda, and salt. Set aside.
  3. In another bowl, beat the softened butter with granulated sugar and brown sugar until light and fluffy, about 3-4 minutes.
  4. Beat in the eggs one at a time, then stir in the vanilla extract.
  5. If using, add a few drops of green food coloring and mix until evenly colored.
  6. Gradually add the dry ingredients to the wet ingredients, mixing just until combined.
  7. Fold in the mint chips gently.
  8. Scrape the dough into the prepared pan and spread evenly. Press a few extra mint chips on top for decoration.
  9. Bake for 25-30 minutes until edges are lightly golden and the center is set but still soft (a toothpick should come out with a few moist crumbs).
  10. Cool completely on a wire rack before slicing. Chill for 20 minutes if firmer bars are desired.
  11. Slice and serve.

Notes

If dough is too sticky, refrigerate for 15 minutes before pressing into pan. Rotate pan halfway through baking to avoid hot spots. Cover with foil if mint chips brown too quickly. For clean slicing, chill bars and use a sharp knife dipped in hot water. Bars can be reheated briefly to restore softness.
