Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • ¾ cup granulated sugar
  • ¾ cup packed light brown sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 ¼ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • 1 cup white chocolate chips
  • 1 cup red and green M&M’s
  • 1 cup crushed pretzels
  • ½ cup chopped pecans or walnuts (optional)
  • ½ cup holiday sprinkles or jimmies

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Line baking sheets with parchment paper.
  2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This takes about 3 minutes.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
  6. Fold in all your mix-ins: semi-sweet chocolate chips, white chocolate chips, M&M’s, crushed pretzels, nuts (if using), and sprinkles. Mix until they are evenly distributed throughout the dough.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. You can press a few extra M&M’s or sprinkles on top for decoration.
  8. Bake for 9 to 11 minutes, or until the edges are golden brown and the centers are still slightly soft. For chewy cookies, err on the side of underbaking.
  9. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For the best sweet and salty balance, use lightly salted pretzels.
  • You can substitute any mix-ins you prefer, such as potato chips or different colored candies, to create your own ultimate cookie recipe.
  • Chill the dough for 30 minutes before scooping if your kitchen is warm; this helps prevent spreading.
  • These are excellent for holiday party desserts and freeze well after baking.
