• 1 cup unsalted butter (at room temperature)
  • 1 cup light brown sugar
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla
  • 3 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 cup chocolate chips (plus more for tops if desired)
  • 1 cup M&M’s (plus more for tops if desired)


  1. Preheat the oven to 325°F. For thick bars, line a 9×13″ pan with foil. For thinner rods, lay out a 15×10″ pan.
  2. Leave an overhang so that you can easily remove it. Then spray with non-stick spray.
  3. In a large bowl, mix butter and sugar in a mixer for 1 minute until creamy. Add the eggs and vanilla and stir until they mix.
  4. Add the flour, baking powder and salt and stir the mixture until it is well blended. Fold in the chocolate chips and M&M’s (save about 1/4 cup for the top).
  5. Scoop the cookie dough into the pan. Then place additional M&M’s and chocolate sprinkles on top.
  6. Bake for 30-35 minutes, or until the top is barely golden brown.
  7. Allow to cool completely, then remove and slice.
  8. Store in an airtight container for up to 3 days.
