Ingredients
- 1 box dark chocolate cake mix (or your preferred chocolate cake mix)
- ½ cup vegetable oil (or melted butter, cooled)
- 2 large eggs
- 1 cup semi-sweet chocolate chips
- 2 tubs dark chocolate frosting
- Rainbow chocolate chips or mini M&M’s for topping
Instructions
- Step 1: In a large mixing bowl, combine the cake mix, vegetable oil, and eggs. Mix together until just incorporated.
- Step 2: Stir in the semi-sweet chocolate chips and candy toppings until evenly mixed.
- Step 3: Preheat your oven to 350°F (175°C) and prepare a cookie sheet by lining it with parchment paper, a silicone baking mat, or by spraying it with nonstick cooking spray.
- Step 4: Use a medium cookie scoop to portion out even-sized cookie dough balls. Place them on the prepared sheet about 2 inches apart.
- Step 5: Chill the cookie dough balls in the refrigerator for 10-15 minutes while the oven preheats.
- Step 6: Bake the cookies for 8-10 minutes, until they are set around the edges but still soft in the center.
- Step 7: Remove cookies from the oven and transfer them to a wire rack to cool completely.
- Step 8: Once cool, frost each cookie with dark chocolate frosting using an offset spatula or pipe the frosting onto the cookies with a piping bag.
- Step 9: Sprinkle rainbow chocolate chips or mini M&M’s over the frosting. Allow the frosting to firm up before serving.
Tips & Variations
- For a richer flavor, substitute vegetable oil with melted butter that has cooled slightly.
- Try adding a pinch of sea salt on top of the frosting to enhance the chocolate taste.
- Use white chocolate chips or your favorite candy pieces to customize the cookies.
- Chilling the dough before baking helps the cookies hold their shape and intensifies the flavors.
Storage
Store the cookies in an airtight container at room temperature for up to 3 days. If frosted, keep them refrigerated and bring to room temperature before serving. You can also freeze unfrosted cookie dough balls for up to 1 month and bake from frozen, adding a couple of minutes to the baking time.

FAQs
Can I use a different cake mix besides dark chocolate?
Yes, you can use any chocolate cake mix you prefer. Using darker or lighter mixes will slightly alter the flavor but still yield delicious results.
Is it necessary to chill the cookie dough before baking?
Chilling the dough helps the cookies hold their shape and improves texture, but if you’re short on time, you can bake them immediately. Just be aware they may spread more during baking.

Ingredients
Cookie Dough
- 1 box dark chocolate cake mix (or any chocolate cake mix of your choice)
- ½ cup vegetable oil (or melted butter, cooled)
- 2 large eggs
- 1 cup semi-sweet chocolate chips
- Rainbow chocolate chips or mini M&M’s (amount as desired)
Frosting
- 2 tubs dark chocolate frosting
Instructions
- Combine Ingredients: In a large mixing bowl, combine the chocolate cake mix, vegetable oil, and eggs. Mix together just until all ingredients are incorporated, avoiding overmixing to keep the cookies tender.
- Add Chips & Candies: Stir in the semi-sweet chocolate chips and rainbow chocolate chips or mini M&M’s until evenly distributed throughout the dough.
- Preheat Oven & Prepare Baking Sheet: Preheat your oven to 350°F. Line a cookie sheet with parchment paper, a silicone baking mat, or lightly spray it with nonstick cooking spray for easy cookie removal.
- Form Cookie Dough Balls: Using a medium cookie scoop, portion out even-sized balls of dough. Place them on a plate and refrigerate for 10-15 minutes while the oven finishes preheating. This chilling helps maintain cookie shape when baked.
- Arrange on Baking Sheet: Place the chilled cookie dough balls onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading during baking.
- Bake: Bake the cookies in the preheated oven for 8-10 minutes. Cookies should be set around the edges but still soft in the center.
- Cool: Remove the cookies from the oven and transfer them to a wire cooling rack. Allow them to cool completely before frosting.
- Frost Cookies: Once cooled, frost each cookie using an offset spatula or put the dark chocolate frosting into a piping bag and pipe it onto the cookies for a neat finish.
- Decorate: Sprinkle additional rainbow chocolate chips or mini M&M’s on top of the frosting for a colorful cosmic effect. Let the frosting set before serving.
Notes
- Chilling the cookie dough before baking helps the cookies hold their shape and results in a thicker texture.

- For uniform-sized cookies, use a cookie scoop to portion the dough evenly.
- Allow cookies to cool completely before frosting to prevent melting and sliding of the frosting.
- Store cookies in an airtight container at room temperature for up to 3 days.
