How to Make Christmas M&M Cookie Bars Step by Step
Ingredients
1 cup unsalted butter (at room temperature)
1 cup light brown sugar
3/4 cup granulated sugar
2 large eggs
2 teaspoons vanilla
3 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
1 cup chocolate chips (plus more for tops if desired)
1 cup M&M’s (plus more for tops if desired)
Directions
Preheat the oven to 325°F (165°C) and line a 9×13-inch or 15×10-inch pan with foil, leaving an overhang; spray with non-stick spray. Cream the butter, brown sugar, and granulated sugar together for 1 minute. Add the eggs and vanilla, mixing until fully combined. Stir in the flour, baking soda, and salt just until a dough forms. Fold in the chocolate chips and M&M’s, reserving about 1/4 cup for topping. Spread the cookie dough evenly into the prepared pan. Sprinkle the remaining M&M’s and chocolate chips over the top. Bake for 30–35 minutes, until the top is just lightly golden. Cool completely in the pan before lifting out with the foil and slicing.

How to Serve Christmas M&M Cookie Bars
These cookie bars are excellent served warm with a scoop of vanilla ice cream on the side. For a festive touch, drizzle some melted white chocolate over the top before serving. Pair them with a glass of cold milk or a warm cup of hot cocoa for a cozy treat.
How to Store Christmas M&M Cookie Bars
To keep your Christmas M&M Cookie Bars fresh, store them in an airtight container at room temperature for up to a week. If you have leftovers, you can also refrigerate them for longer shelf life. To reheat, just pop them in the microwave for a few seconds until warm. If you want to keep them for even longer, you can freeze the bars. Just wrap them tightly in plastic wrap and then in aluminum foil. They will last for up to three months in the freezer.
