  • 1 cup (2 sticks) unsalted butter
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 cups plus 2 Tablespoons and 1/4 cups all-purpose flour
  • 1 and 1/2 cups M&Ms


  • Preheat your oven to 325 degrees F.
  • Melt the 2 sticks of butter directly in your cast iron skillet over medium heat. Allow it to melt completely and slowly bubble.
  • Turn the heat to low and add in the sugars. Mix well until uniform.
  • Turn the heat off and take the cast iron pan off the stove. Add in the eggs and vanilla and mix well.
  • Add the baking soda, salt and flour and mix well. Fold in the M&Ms.
  • Bake in your preheated oven for 25-35 minutes or until golden brown. Top with additional M&Ms for a prettier presentation. Allow to cool slightly before serving (preferably with a scoop of ice cream).


Leftovers should be stored, covered, at room temperature and will keep for several days.
