Ingredients
Scale
- 1 cup unsalted butter: adds richness and creates chewy edges
- 1 cup brown sugar: provides moisture and depth of flavor
- 1/2 cup granulated sugar: balances sweetness and crisp texture
- 2 large eggs + 1 egg yolk: adds structure and richness
- 2 teaspoons vanilla extract: enhances flavor
- 2 cups all-purpose flour: gives the cookies structure
- 1 teaspoon baking soda: helps cookies rise
- 1 teaspoon baking powder: balances texture and lift
- 1/2 teaspoon salt: balances sweetness
- 1 1/2 cups old-fashioned oats: adds chewiness and hearty texture
- 1 cup red and green M&M’s: festive color and chocolate flavor
- 1 cup pretzel twists, roughly crushed: adds crunch and saltiness
- 3/4 cup semi-sweet or dark chocolate chunks: melty chocolate flavor
- 3/4 cup white chocolate chips: creamy sweetness
Instructions
- Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
- In a large mixing bowl, beat together butter, brown sugar, granulated sugar, and vanilla until creamy and fluffy.
- Add the eggs and extra yolk one at a time, mixing until smooth.
- Mix in flour, baking soda, baking powder, and salt. Stir until just combined.
- Fold in oats, 1 cup of M&M’s, crushed pretzels, chocolate chunks, and white chocolate chips.
- Roll dough into 1/4 cup-sized balls and place them 3 inches apart on prepared sheets.
- Bake for 8 minutes, rotate pan, then bake an additional 2 minutes. Press remaining M&M’s on top of cookies and bake 2–3 more minutes until golden.
- Allow cookies to cool on the baking sheet for several minutes before transferring to a wire rack. Enjoy warm or store in an airtight container.
Notes
- Omit the extra egg yolk for thicker cookies with less spreading.
- Press extra M&M’s on top mid-bake for a festive finish.
- Do not overbake — cookies will continue to cook as they cool.
- Store in an airtight container for up to 4 days or freeze for 3 months.
- To keep cookies soft, place a slice of bread in the container.
