Preheat oven to 375°F (190°C) and line baking sheets with parchment paper.

Beat together unsalted butter, granulated sugar, and light brown sugar until light and fluffy (2-3 minutes).

Mix in plain Greek yogurt and vanilla extract until well combined (1-2 minutes).

Whisk together the all-purpose flour, baking soda, and salt in a separate bowl, then gradually add to the wet ingredients and mix gently until just combined (about 30 seconds).

Fold in the semi-sweet chocolate chips.

Drop rounded portions of dough onto prepared baking sheets, leaving at least 2 inches of space between each cookie.

Bake for 9-12 minutes until edges are golden and centers remain slightly soft. Cool on baking sheets for 10 minutes before transferring to a wire rack.
