1-First Step: Preheat and Prep Mise en Place Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper to prevent sticking and ensure even browning. Measure out 2 1/4 cups all-purpose flour, 1 tsp baking soda, and 1 tsp salt into a bowl. This dry mix sets the foundation for your Christmas M&M cookies recipe. Softening 1 cup butter takes about 30 minutes at room temp, or microwave in short bursts. For vegan adaptations, prepare flax eggs ahead. Gather 3/4 cup each granulated and brown sugar, 1 tsp vanilla, 2 eggs, 1 cup chocolate chips, and 1 1/2 cups Christmas M&Ms. Organizing prevents mid-mix scrambles, ideal for busy parents.

2-Second Step: Cream Butter and Sugars Cream softened butter with sugars using a mixer on medium speed until light and fluffy, about 2 minutes. Scrape bowl sides for even texture.

Dough should be thick and scoopable. For red green M&M cookies, press extras on balls before baking. Chill dough 30 minutes if spreading concerns you, especially in warm kitchens. This prevents flat cookies and enhances flavor.

5-Fifth Step: Scoop and Bake Scoop 2-tablespoon dough balls onto sheets, spacing 2 inches apart. Bake 9-11 minutes until edges turn golden. Centers stay soft do not overbake for chewy holiday cookies. Rotate sheets halfway for even heat. Yields 36 cookies. Cool on sheet 5 minutes to set, then transfer to wire rack. Multiple batches take 45-60 minutes total.
