Ingredients:

  • 1 cup (225g) unsalted butter, softened
  • 1 cup (250g) creamy peanut butter
  • 1 cup (200g) packed light brown sugar
  • 1/2 cup (100g) granulated white sugar
  • 2 large eggs
  • 1 tsp (5ml) vanilla extract
  • 1 tsp (5g) baking soda
  • 1/2 tsp (3g) salt
  • 2 cups (180g) all-purpose flour
  • 3 cups (270g) old-fashioned rolled oats
  • 1 cup (170g) semi-sweet chocolate chips
  • 1 cup (190g) red and green M&Ms
  • 1 cup (110g) crushed salted pretzels
  • 1/2 cup (90g) white chocolate chips

Instructions:

  1. Beat the softened butter, peanut butter, and both sugars on medium-high until the mixture is pale, fluffy, and completely combined.
  2. Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract.
  3. Sift in the baking soda and salt, then gradually add the flour and rolled oats. Mix on low speed just until the flour disappears.
  4. Using a spatula, gently fold in the semi-sweet chocolate chips, M&Ms, crushed pretzels, and white chocolate chips until evenly distributed.
  5. Scoop rounded tablespoons of dough onto lined baking sheets, spacing them 2 inches apart. Chill the scooped dough balls for 30 minutes.
  6. Bake at 350°F (175°C) for 10-12 minutes until the edges are set and slightly golden, but the centers still look slightly soft.
