Heat oven to 350 degrees. Use some butter to grease your bundt cake pan. Mix semi-sweet chocolate, stick of butter, marshmallows, vanilla, and hot fudge in large bowl. Melt in the microwave for about 1- 1/2 minutes (don’t burn!) Dip biscuits in mixture and then roll in sugar (as if you are breading chicken) and then layer the bundt pan with the covered biscuits until full. Bake for 45 mins and ALLOW to cool at least 5 mins BEFORE turning bundt pan over to serve (or else you will create a sticky mess). Enjoy!
