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

In a large mixing bowl, combine Devil’s Food Cake Mix, eggs, and canola or vegetable oil. Mix until well blended and thick.

Scoop and roll 1.5 tablespoons of dough into balls. Place on prepared sheets, leaving space for expansion.

Bake for 8 to 10 minutes, until edges are set but centers are slightly soft. Cool on sheets for 5 minutes before transferring.

Beat softened butter until creamy, then add powdered sugar, black cocoa powder, vanilla extract, and milk until smooth.

Frost cooled cookies and decorate with M&Ms, sprinkles, licorice, and chocolate ears.

Let decorated cookies sit at room temperature for 30 minutes to an hour to set.
