Cake mix cookies are my favorite type of cookies to bake. Those soft puffy cookies just make me so happy. Plus, there are so many ways you can change them up.
I love that you can add different things to these easy cookies to change them up each time. A few of our favorites are these cookies and cream cookies, these Snickers stuffed cookies, and these chocolate M&M cookies.
Since we had another chocolate cake mix in the pantry, I decided to make more chocolate cookies. But to change it up, I added a toasted marshmallow and a candy bar.

How to Make Chocolate Marshmallow Cookies
Get ready to be amazed by how simple it is to make these delicious marshmallow cookies. Simply mix the dough, pop it in the fridge, and then let the oven work its magic. It's truly as easy as that.
- Make the dough. Mix together the box of cake mix, butter, cream cheese, egg, and vanilla extract until a light and fluffy dough forms.
- Refrigerate the dough. Place the bowl in the fridge and chill the cookie dough for at least 60 minutes.
- Roll and bake. Scoop the dough into 36 even balls, roll into a ball, and place 12 on a baking sheet. Bake for 8 minutes.
- Add the toppings. Place a cut marshmallow on top of the hot cookies. Place them back in the oven under the broiler for 1-2 minutes. Let them cool on the pan for 2-3 minutes. Then remove and press a small candy bar into the top of each one.
Keep the cooled cake cookies in an airtight container on the counter at room temperature. They will stay soft and delicious for 4-5 days.
Tips and Tricks
- Want more chocolate? Add ¾ cup miniature chocolate chips to the cookie dough before chilling.
- Chill the dough for at least 60 minutes. You can roll it earlier, but it will stick to your hands more. They also stay puffier when they bake with chilled dough.
- While the dough is chilling, cut your marshmallows in half and break apart the candy bars.
- Roll the dough into 36 even dough balls. I find it easiest to roll the dough into one giant log and then cut that into 3 even pieces. Each of those pieces needs to be cut into 12 even chunks.
- Keep an eye on the cookies while the marshmallows are toasting in the oven. They can and will go from golden brown to burnt in a matter of seconds.
- Place the cookies on a wire rack to cool completely before storing them in a container.
- Use a sheet of parchment or wax paper between the layers of cookies because it will keep them from sticking together.
Yes, any cake mix will work for this cookie recipe. The chocolate and marshmallow combo tastes great with vanilla, chocolate, or strawberry.
This particular cake mix cookie recipe makes 36 cookies. They are the perfect size for the toasted marshmallow.
Yes, they are a great cookie to make 1-2 days ahead of time because they stay soft for days. You can also make the dough ahead of time. Just keep it in a covered container in the fridge until you need/want cookies.
