Preheat oven to 175°C (350°F). Line a baking sheet with parchment paper or a non-stick silicone baking mat. Separate the green, orange, and purple M&M's into a small bowl.

In a mixing bowl, sift together the flour, cocoa powder, baking soda, and salt. Set aside.

In a large mixing bowl, use an electric mixer to cream the butter with granulated and brown sugars until light and fluffy, about 2-3 minutes.

Beat in eggs and vanilla extract until well incorporated and smooth.

Fold half of the M&M candies into the dough, distributing them evenly.

Shape the dough into 2-inch balls and place on the prepared baking sheet, leaving space between each. Press the remaining M&M's onto the top of each dough ball.

Bake for 9-11 minutes until edges are set but centers remain slightly soft. Allow to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Microwave the white frosting in a microwave-safe bowl for 15 seconds to soften. Stir in the neon green gel food coloring until achieving a vibrant green hue.
