Can I make Christmas Monster Cookies ahead of time?

Yes, you can bake them a few days in advance. Once cooled, store them in an airtight container at room temperature for up to four days. If you’d like to prep further ahead, freeze the dough balls and bake straight from frozen (just add a couple of extra minutes to the bake time).

Can I make Christmas Monster Cookies without pretzels?

Absolutely. While the pretzels add a nice salty crunch, they aren’t essential. You can swap them with chopped pecans, walnuts, or simply leave them out for a classic chewy cookie texture.

Why are my Christmas Monster Cookies spreading too much?

These cookies are designed to spread slightly for crispy edges and soft centers. However, if they’re flattening too much, try omitting the extra egg yolk and chilling the dough for 15–30 minutes. Also ensure your butter isn’t too warm before mixing.

Ingredients

1 cup unsalted butter, softened
1 cup brown sugar
1/2 cup granulated sugar
2 teaspoons vanilla extract
2 large eggs
1 egg yolk
2 1/2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon kosher salt
1 1/2 cups old-fashioned oats
1 1/2 cups red and green holiday M&M’s, divided
1 cup chopped salted pretzel twists
1 cup semi-sweet or dark chocolate chunks
1/2 cup white chocolate chips

Instructions

Preheat the oven to 350°F and line a baking sheet with parchment paper.
In a large mixing bowl, beat together the butter, brown sugar, granulated sugar, and vanilla until combined.
Beat in the eggs and the egg yolk, one at a time, until fully incorporated.
Add the flour, baking soda, baking powder, and salt; mix to combine.
Stir in the oats.
Fold in 1 cup of the M&M’s, the pretzels, chocolate chunks, and white chocolate chips.
Roll the dough into 1/4 cup-sized balls and place them 3 inches apart on the prepared baking sheet.
Bake for 8 minutes, then rotate the pan and bake for another 2 minutes.
Pull the pan out and press the remaining M&M’s into the cookies, then bake for an additional 3 minutes.
Remove from the oven and let the cookies cool on the baking sheet.
Serve warm or store in an airtight container for up to 4 days.

Notes

To reduce spreading, omit the extra egg yolk for a thicker cookie.
For the best visual effect, press extra M&M’s on top before the final minutes of baking.
No chilling required—ideal for quick holiday baking.
Cookies will continue to cook slightly while cooling on the baking sheet.
