Ingredients
- 1/2 cup unsalted butter, melted and cooled
- 3/4 cup brown sugar, packed
- 1/4 cup granulated sugar
- 1 large egg
- 1 egg yolk
- 1 1/2 tsp pure vanilla extract
- 1 3/4 cups all-purpose flour

Instructions
- Preheat oven to 350°F. Line baking sheets with parchment paper.
- Melt butter and allow to cool 5–8 minutes until no longer warm to the touch.
- Whisk cooled butter, brown sugar, and granulated sugar together until smooth and glossy.
- Add egg, egg yolk, and vanilla. Whisk until pale and slightly thickened.
- Whisk flour, cornstarch, baking soda, and salt together. Fold into wet ingredients just until combined.
- Fold in 1/2 cup of the green M&Ms, white chocolate chips, and sprinkles gently.
- Scoop dough into 2-tablespoon portions and place 2 inches apart on baking sheets.
- Press reserved M&Ms and extra white chocolate chips onto tops of dough balls.
- Bake 10–12 minutes until edges are set and centers look slightly underdone. Optional: gently bang pan during final 2 minutes for chewier texture.
- Cool on baking sheet 8–10 minutes before transferring to wire rack.
Notes
Cool melted butter before mixing to prevent excess spreading. Do not overmix after adding flour. Remove cookies while centers look slightly underdone — they finish setting on the pan. Reserve some M&Ms to press on top before baking for a bakery-style festive look.
