Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

Whisk together the flour and baking soda in a medium bowl; set aside.

Cream the softened butter, granulated sugar, and brown sugar in a large mixing bowl until light and fluffy.

Add the large eggs one at a time, mixing well after each addition. Then, mix in the vanilla extract until fully combined.

Gradually incorporate the dry flour mixture into the wet mixture until just combined. Then, fold in the M&M candies until evenly distributed.

Drop spoonfuls of dough onto the prepared baking sheets, spacing them about two inches apart.

Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are golden brown.
