Cuisine: American
Servings: 8 people
Author: Gemma Stafford
Ingredients
  • 2 ½ cups (10½oz/355g) all-purpose flour
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (8oz/225g) butter
  • 1 cup (6oz/170g) dark brown sugar
  • ½ cup (4oz/115g) granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • ¾ cup (4½oz/130g) M&M's
Instructions
  1. Preheat the oven to 350°F (180°C).

  2. In a bowl, whisk together the flour, baking powder, soda, and salt. Set aside.

  3. Heat a 12-inch cast iron skillet over low heat. Add the butter and let it melt completely.

  4. Remove from the heat and stir in the sugars with a wooden spoon.

  5. Whisk together the eggs in a bowl. Add it to the skillet and mix in right away with a spoon, quickly mixing so the eggs don’t cook from the heat. Stir in the vanilla extract.

  6. Stir in the dry ingredients until just combined. Lastly, fold in the M&M's. Wipe down any flour that is left on the sides.

  7. Bake the cookie for 20 to 22 minutes, or until it’s mostly set in the center. (take care not to overbake or it will not be gooey in the middle.

  8. Serve warm from the oven with vanilla ice cream.
