Heat the heavy whipping cream on stove top, stirring so that it doesn't burn.
Meanwhile, pour the chocolate chips into a microwave safe bowl.
Once the whipping cream is boiling, remove from the heat and pour directly over the chocolate chips
Let mixture stand 4-5 minutes.
Add ground cinnamon to the bowl.
Stir the chocolate mixture until smooth and creamy. Tip: if the chocolate chips do not fully melt by the heat of the whipping cream, microwave the bowl for 30 seconds.
Add mixture to the piping bag and pipe the chocolate into the mold, approximately halfway. If not using a piping bag, spoon mixture into the mold.
Sprinkle any desired toppings on top of the chocolate. I used crushed candy canes, mini marshmallows and Christmas themed sprinkles.
Place the popsicle sticks into the center of each chocolate square. They should stand straight up.
Put the mold in the refrigerator and allow to set up, approximately 3 hours.
Once the chocolate has set up, remove each stick from the mold.
Heat up milk of choice or water, and stir in the chocolate until completely dissolved. Enjoy!
