  • 1 cup (2 sticks) unsalted butter room temperature
  • 1 cup granulated sugar
  • 1 cup brown sugar packed
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1 teaspoon baking soda
  • 1 teaspoon corn starch
  • 1/2 teaspoon salt
  • 3 cups all-purpose flour
  • 1 cup chocolate chips
  • 1 and 1/2 cups M&M candies


  • Preheat your oven to 350 degrees F. Generously grease or line a standard 9" x 13" baking pan and set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl if using a handheld mixer, cream the butter and sugars on medium speed until light and fluffy, about 2-3 minutes.
  • Add the eggs and vanilla and mix well. Then add the baking soda, corn starch, salt and flour.
  • Turn the mixer off and fold in the chocolate chips and M&M candies by hand.
  • Transfer the dough to your prepared an and spread it out evenly. Make sure you smooth the top so there are no bumps.
  • Bake in your preheated oven for 35 minutes or until the tops start to turn a light golden color.
  • Allow the bars to cool before slicing and serving.


Bars should be stored in an airtight container at room temperature and will keep for several days.
