Instructions:
- In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
- In the bowl of your stand mixer, beat the softened butter, granulated sugar, and brown sugar together on medium speed until light, pale, and fluffy (this takes 3-5 minutes).
- Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until just combined. Scrape down the sides of the bowl.
- Gradually add the dry ingredients to the wet mixture on low speed. Mix only until just combined and no streaks of flour remain. Do not overmix.
- Wrap the dough tightly in plastic wrap and flatten slightly into a disc. Chill in the refrigerator for at least 30 minutes.
- Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper.
- Scoop dough portions (about 1.5 tablespoons each) onto prepared sheets, spacing them 2 inches apart.
- Bake for 10–14 minutes. Cookies are done when the edges are set and golden brown, but the centres still look slightly soft.
- Let cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
