Ingredients

Cookie Dough

  • 1 package chocolate cake mix (15.25 ounces)
  • 2 eggs
  • 5 tablespoons vegetable oil

Frosting

  • 1/2 cup butter (softened)
  • 2 tablespoons unsweetened cocoa powder
  • 2 1/2 tablespoons milk
  • 1/2 teaspoon vanilla extract
  • 2 1/2 cups powdered sugar

Instructions

  1. Preheat oven: Preheat your oven to 350°F (175°C) and line a cookie sheet with parchment paper to prevent sticking and ensure even baking.
  2. Mix dough: In a large bowl, combine the chocolate cake mix, eggs, and vegetable oil. Stir vigorously until well blended and the dough forms a thick consistency suitable for scooping.
  3. Scoop dough: Use a cookie scoop or heaping tablespoon to drop rounded balls of dough onto the prepared cookie sheet, spacing each about 2 inches apart to allow room for spreading.
  4. Bake cookies: Bake in the preheated oven for 7 to 8 minutes until the cookies are just set but still soft. Remove from the oven and let them cool on the baking sheet for about 5 minutes to firm up slightly.
  5. Prepare icing: While cookies cool, melt the softened butter in a small saucepan over medium heat. Whisk in the unsweetened cocoa powder, milk, and vanilla extract until the mixture becomes smooth and well combined.
  6. Frost cookies: Remove the saucepan from heat and gradually stir in the powdered sugar until the frosting reaches a smooth, drizzleable consistency. If the icing is too thick, add a splash more milk to thin it. Drizzle the frosting evenly over the warm cookies and allow it to set before serving.

Notes

  • Do not overbake the cookies; they should be soft when removed from the oven.
  • For easier cleanup, use parchment paper or a silicone baking mat on the cookie sheet.
  • If the frosting hardens too quickly, gently rewarm it over low heat with a little milk to soften for drizzling.
  • Store cookies in an airtight container at room temperature for up to 3 days.
