Ingredients

  • 1 cup unsalted butter, at room temperature

  • 3/4 cup dark brown sugar, packed

  • 1/2 cup granulated sugar

  • 2 teaspoons vanilla extract

  • 2 large eggs

  • 1 egg yolk

  • 2 cups all-purpose flour

  • 1 teaspoon baking soda

  • 1/2 teaspoon baking powder

  • 1 teaspoon salt

  • 1 cup old-fashioned oats

  • 1 1/4 cups red and green M&Ms

  • 1 cup salted pretzel twists, broken into pieces

  • 1 cup semi-sweet chocolate chunks

  • 1/2 cup white chocolate chips

  •  

Instructions

  1. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large mixing bowl, beat together butter, dark brown sugar, granulated sugar, and vanilla extract until well combined and creamy.
  3. Add eggs and egg yolk one at a time, beating after each addition until just incorporated.
  4. Add flour, baking soda, baking powder, and salt. Mix until just combined.
  5. Stir in oats until evenly distributed.
  6. Fold in 1 cup of M&Ms, pretzel pieces, chocolate chunks, and white chocolate chips.
  7. Roll dough into 1/4 cup-sized balls and place 3 inches apart on prepared baking sheets.
  8. Bake for 8 minutes, then rotate the pan and bake for another 2 minutes.
  9. Remove from oven and gently press remaining M&Ms into tops of cookies.
  10. Return to oven for an additional 2–3 minutes until edges are set and centers are slightly underdone.
  11. Let cookies cool completely on the baking sheet before transferring or storing.

Notes

  • No chilling needed—dough can be baked immediately.
  • Add M&Ms near the end of baking for a vibrant top appearance.
  • Use room temperature butter for best creaming results.
  • Cookies will continue to bake as they cool; remove when centers look underdone.
  • For thicker cookies, omit extra egg yolk.
