An intense chocolate cookie with an extra dose of chocolate in the frosting. Cake mix cookies are the ultimate shortcut to sweet and easy cookies ready in under 30 minutes. It's a versatile, no-fuss recipe that requires only a handful of ingredients. Perfect for picnics, barbecues, children's birthdays, potlucks, and bake sales.

  • Total Time: 20 minutes
  • Yield: 24 cookies



For the cookies:

  • 15.25 oz box (435g) chocolate cake mix
  • 2 eggs, at room temperature
  • 1/2 cup sunflower oil

For the chocolate ganache:

  • 2 0z semisweet chocolate, chopped
  • 1/4 cup whipping cream


  1. Preheat the oven to 350°F/180°C.
  2. Combine the chocolate cake mix, eggs, and vegetable oil in a mixing bowl.
  3. Stir until all the ingredients are well combined. The mixture will be thick, shiny, and sticky.
  4. Line a baking sheet with parchment paper or lightly grease it.
  5. Scoop spoonfuls of the dough onto the prepared baking sheet, spacing them a few inches apart. Use a cookie scoop or two spoons to drop them. 
  6. Bake the cookies for about 10 minutes, until the edges are dry and the middle is puffed. The cookies may appear slightly undercooked in the center but will firm up as they cool.
  7. Let them cool for 10-15 minutes on a wire rack until you can easily (and carefully) remove them from the baking sheet. 
  8. Transfer them to a cooling rack to cool completely.
  9. Repeat the process with the remaining dough until all the cookies are baked.
  10. Once the cookies have cooled completely, you can store them in an airtight container for up to a week.

For the chocolate topping:

  1. Heat the cream in a small saucepan until it almost starts to boil.
  2. Put the chopped chocolate in a bowl and add the hot cream. Let it stand for 1 minute and whisk it to combine well.
  3. Whisk until the chocolate has completely dissolved and the mixture is smooth. 
  4. Let cool until it has a spreading consistency. Spread small amounts over the cooled cookies and add sprinkles if you want to.
  5. Keep covered and refrigerated if making it in advance.


  • Baking time: keep in mind that all ovens and pans are different, even if they look similar. The baking time in my recipes is as accurate as it can be, but it might take you more or less time. You can use a thermometer(like the OXO oven thermometer) to check that your oven is at the right temperature. I recommend you keep track of how your oven works and what tiny details you might need to adjust. 
  • Cake mix brands: no matter which one you use, they may have slight variations in ingredients and texture, but the overall process should remain the same.
