Mix the butter and coconut sugar till everything is completely blended. Add in the egg and vanilla extract to the above and again mix everything together.
Add whole wheat flour, hot chocolate mix, baking soda, baking powder and salt to the wet mixture and mix everything.
Add semi-sweet chocolate chips and mix again. Optionally, refrigerate the cookie dough for around 15-20 minutes.
Remove the cookie dough from the refrigerator. Line a baking tray with parchment paper. Preheat oven to 375 degree F (or 190 degree Celsius). Take around 1 – 2 tablespoon of cookie dough in your hands, form a ball and flatten a little and repeat for all cookies. Top the cookies with Red and Green M&Ms.
Bake the cookies for around 10-12 minutes in the preheated oven, or till you see creases on top of the cookies. The cookies will be soft to touch, but once cooled, they will be fine.
Remove the cookies from the oven, and immediately top them with one mini marshmallow each.
The Healthy & Soft Hot Chocolate Cookies are now ready to be served warm, or these can also be stored in an air-tight container for around a week.
