Ingredients
Scale
Cookie Dough
- 1 box (13.25 ounces) chocolate cake mix
- 2 large eggs
- ⅓ cup vegetable oil
Frosting
- ½ cup (1 stick) unsalted butter
- 2 tablespoons cocoa powder
- 3 tablespoons milk
- 1 teaspoon vanilla extract
- 2½ cups powdered sugar
Instructions
- Preheat Oven and Prepare Baking Sheet: Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat to prevent the cookies from sticking during baking.
- Make the Cookie Dough: In a large mixing bowl, combine the chocolate cake mix, eggs, and vegetable oil. Stir thoroughly until you have a thick, sticky dough with no dry pockets of cake mix visible.
- Portion the Dough: Using a cookie scoop or spoon, drop rounded balls of dough onto the prepared baking sheet. Make sure to space them about 2 inches apart so the cookies have room to spread evenly.
- Bake the Cookies: Bake the cookies for 8 to 10 minutes. The edges should appear set, while the centers may still look slightly soft. Avoid overbaking as the cookies firm up while cooling.
- Prepare the Frosting: While the cookies bake, melt the unsalted butter over medium heat in a medium saucepan. Once melted, whisk in cocoa powder and milk until smooth, then remove from heat.
- Finish the Frosting: Stir the vanilla extract into the chocolate mixture. Gradually whisk in powdered sugar until the frosting becomes smooth and glossy. Adjust thickness by adding more milk if too thick or more powdered sugar if too thin.
- Frost the Cookies: Allow the cookies to cool on the baking sheet for 2 to 3 minutes after baking. While still warm, spoon approximately one tablespoon of warm frosting onto the center of each cookie, spreading gently toward the edges.
- Cool and Set: Transfer the frosted cookies to a wire rack to cool completely. The frosting will set and harden slightly as the cookies cool, creating a perfect chocolate finish.
Notes
- For even baking, make sure your cookie balls are uniform in size.
- Use a silicone baking mat or parchment paper to prevent sticking and ease cleanup.
- Don’t overbake; removing the cookies when centers are still soft ensures a moist texture.
- Adjust frosting thickness according to preference by adding milk or powdered sugar.
- Store cookies in an airtight container at room temperature for up to 3 days.
