In a large mixing bowl, cream together the butter, brown sugar, and raw cane sugar using a hand mixer. Once creamy, add the eggs and vanilla extract and mix again.

In a separate bowl, combine the flour, hot cocoa mix, baking powder, corn starch, and salt. Add this to the wet ingredients and mix until just combined. Do not over mix.

Add the chocolate chips and dehydrated marshmallows and stir them in with a spoon.

Cover and refrigerate for at least 30 minutes while your oven preheats.

Preheat the oven to 375 degrees F.

Scoop the cooled dough onto a lined baking sheet and bake for 10-12 minutes or until the middles are just cooked through.
