These cookies are my version of that treat, and trust me, they’re just as delicious.

How to Make Crumbl Copycat Chocolate Mallow Cupcake Cookies

Line two baking sheets with parchment paper to keep the cookies from sticking and to make cleanup easier.

On a plate, place a piece of plastic wrap. Use a teaspoon or melon baller to scoop out the marshmallow fluff and form mounds. Freeze for at least 10 minutes while you work on the cookie dough.

In the bowl of a stand mixer, cream the softened butter, brown sugar, and sugar together until smooth. This step makes the cookies soft and chewy. Then, add the egg and vanilla extract, mixing until fully combined.

Add the cocoa powder, flour, baking soda, and salt to the bowl. Mix until everything is well combined, scraping down the sides of the bowl as needed. Then, divide the dough into eight equal portions. Roll each portion into a ball, then flatten it into a disc about ½ inch thick.

Quickly remove the marshmallow fluff from the freezer. Place a mound of fluff in the center of each dough disc, then fold the dough around it to seal the fluff inside.

Place the cookies on the baking sheet and bake for about 10 minutes, or until the centers are set. Let the cookies cool completely before decorating them.

In a medium bowl, combine the semi-sweet chocolate chips and heavy cream. Microwave for 30 seconds at a time, stirring in between, until the chocolate is melted and smooth. Spoon the ganache over the tops of the cooled cookies.

In a small bowl, melt the white chocolate chips and transfer them to a piping bag. Pipe the white chocolate in a loop pattern over the ganache. Let the cookies set for a bit until the topping hardens slightly.

Storage Tips

To keep these cookies fresh, store them in an airtight container in the fridge for up to 3 days. They may soften a bit, but the marshmallow center stays delicious. If you’re making them in advance, you can freeze the dough before baking. Just be sure to thaw it for 30 minutes before baking so they cook evenly.
