These Hot Chocolate Bomb Cookies bring together the fun of a molten chocolate center and gooey marshmallows all wrapped inside a rich, chunky cookie. Serve them straight from the oven for a cozy winter treat or any time you crave something over the top and chocolatey.
The first time I made these cookies for a snow day movie night they disappeared before the movie even started and now my friends request them whenever the weather turns chilly

I love using dark chocolate here because the bittersweet creamy ganache keeps these cookies from being overly sweet and reminds me of watching holiday movies with my sister covered in blankets and sneaking cookies off the tray before they finished cooling
Storage Tips
Store cooled cookies in an airtight tin at room temperature for three days For longer storage freeze raw dough balls with filling on a sheet until hard then transfer to a bag and bake from frozen adding two extra minutes to bake time Freezing after baking also works and you can microwave each cookie fifteen seconds for a gooey center even from frozen
Ingredient Substitutions
You can use semisweet chocolate if dark is too intense for your taste Swap mini marshmallows for slightly chopped larger ones if needed For a nutty variation stir in half a cup chopped toasted pecans with the dough Dairy free butter and coconut cream can sub for butter and heavy cream but taste and texture will change
Serving Suggestions
Serve these cookies slightly warm with a tall glass of milk or a mug of coffee For an extra indulgent treat pile a few cookies into a bowl and top with vanilla ice cream Their dramatic gooey center also makes them a fun choice for holiday dessert boards
