Ingredients

  • 2 tablespoons unsalted butter, room temperature 30g
  • 1 ½ tablespoons light brown sugar 24g
  • 1 ½ tablespoon granulated sugar 18g
  • 1 tablespoon whisked egg
  • ¼ teaspoon vanilla extract
  • 6 tablespoons all-purpose flour 46g
  • 1/8 teaspoon baking powder
  • 1/16 teaspoon salt
  • 2 tablespoons mini M&Ms (plus more for topping the cookie if desired)

Instructions

  • Preheat oven to 350°F and line a small baking sheet with parchment paper.
  • Add the butter, brown sugar, and granulated sugar to a small bowl and cream together with a fork until totally combined and smooth.
  • Add the whisked egg and the vanilla extract into the dough. Use the fork to incorporate completely. Do not overmix.
  • Add the flour, baking powder, and salt and mix until just combined. Gently mix in the m&ms. The dough will be quite sticky!
  • Place the dough on the middle of the parchment paper and form into a thick round-ish disk shape. It's quite sticky, so just do your best. It should be around 1" thick.
  • Bake the cookie about 17-18 minutes until it has spread, puffed, the edges are golden brown, and the center is set (but still gooey inside).
  • Allow the cookie to cool before digging in. Ideally it needs 15 minutes or more to cool. If you like, try topping the warm cookie with vanilla ice cream for an incredible dessert.

Notes

Make-Ahead: The cooled cookie can be stored at room temperature for 2-3 days in an air-tight container if you want to bake it in advance or save some for later. Enjoy!
