1-First Step: Mise en Place Measure out all ingredients. Soften butter at room temperature for 30 minutes or microwave in 10-second bursts. Chop 1/2 cup of the M&Ms for dough incorporation; reserve the rest whole for topping. This prep ensures smooth mixing and even distribution of chocolate m&m pieces.

2-Second Step: Dry Ingredients In a medium bowl, whisk together flour, baking soda, and salt. Set aside. This uniform blend prevents pockets of leavening for consistent cookie texture in your holiday cookies.

3-Third Step: Cream Wet Ingredients In a large bowl, beat softened butter, granulated sugar, and brown sugar with an electric mixer on medium speed for 2-3 minutes until light and fluffy. Scrape down sides. Add vanilla extract and eggs one at a time, beating well after each. The mixture should look creamy and pale, trapping air for tender m&m cookies.

4-Fourth Step: Combine Wet and Dry Gradually add dry mixture to wet on low speed. Mix just until combined, about 1 minute. Avoid overmixing to keep cookies soft. Dough will be thick and sticky.

5-Fifth Step: Fold in M&Ms Gently stir in chopped M&Ms and chocolate chips with a spatula. Reserve 1/2 cup whole M&Ms for pressing on top. This step packs every bite with festive chocolate m&m goodness.

6-Sixth Step: Scoop and Shape Using a 1.5-tablespoon cookie scoop or spoon, drop dough balls 2 inches apart on prepared sheets. Flatten slightly with palm. Press 3-4 whole M&Ms into each top for that classic holiday m&m cookie recipe look.

7-Seventh Step: Bake Bake one sheet at a time in the middle rack for 9-11 minutes. Edges should be golden, centers soft. Cookies firm up as they cool. Rotate sheet halfway for even baking.

8-Final Step: Cool and Serve Cool on sheet for 5 minutes, then transfer to wire rack. Enjoy warm or store for gatherings. Pair with milk for potlucks. These festive m&m holiday cookies shine at picnics or church events.
