Preheat your oven to 350 F (175 C). Line baking sheets with parchment paper.
In a large bowl, cream together softened butter and granulated sugar until light and fluffy.
Beat in the eggs, one at a time, ensuring each is well incorporated. Stir in vanilla extract.
In a separate bowl, whisk together all-purpose flour, cocoa powder, baking soda, and salt.
Gradually add the dry ingredients to the butter and sugar mixture, mixing just until combined.
Gently fold in the M&M candies until evenly distributed throughout the cookie dough.
Scoop out tablespoon-sized portions of dough and roll them into balls. Place them on the prepared baking sheets, leaving enough space between each.
For a visually appealing touch, press a few additional M&M candies onto the top of each cookie dough ball.
Bake in the preheated oven for 10-12 minutes or until the edges are set. The centers should still be slightly soft.
Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. Dive into the colorful and irresistibly chocolatey world of M&M Chocolate Cookies.
