1 1/2cupsmini marshmallows, frozen if possible but not necessary (see note)
Instructions
In a large bowl, cream butter and sugars until smooth. Beat in eggs and vanilla until combined.
In a separate bowl, whisk together the flour, hot chocolate mix, salt, baking powder, and baking soda. Add the dry ingredients to the wet ingredients slowly until incorporated. The dough will be thick.
Mix in the milk chocolate chips, semi-sweet chips, and marshmallows. Chill the dough at this point for 30 minutes for extra thick cookie but it's not necessary.
Preheat oven to 350 degrees F and line baking sheets with parchment.
Make cookie dough balls, around 1 1/2 tablespoons each, and place onto prepared baking sheets lined with parchment paper. Make sure to cover the marshmallows with the dough. They can be poking out a little (which makes for a pretty cookie) but if they're completely exposed they can spill out and stick to your pan.
Bake for 8-10 minutes or until edges are golden brown. The cookies will still look soft. They will continue to cook on the cookie sheet as they cool. Let cool for 5 minutes before removing from pan. I love these warm. If your eating them after they have cooled you can warm them in the microwave for 10 seconds. Store in an airtight container.
Notes
Freezing the marshmallows to help keep their shape and to not let them melt out of the cookies but I've done it both ways and it's not required.
