Prepare the chocolate mixture. Add cream, milk, chocolate, sugar, and cinnamon to a saucepan over medium heat. Once mixture is hot and starts to boil, lower heat to low and simmer for 15 minutes to allow the cinnamon flavor to fully infuse. Stir occasionally with a wooden spoon or spatula to prevent scorching the chocolate and break up any large pieces of chocolate until it is completely dissolved.
Strain and cool. Allow mixture to cool and then strain through a fine-mesh sieve into a heat-proof bowl with a spout for easy pouring. Refrigerate until chilled or cool bowl with chocolate mixture over an ice bath (larger bowl with ice and water).
Prepare popsicles. Pour mixture into popsicles molds (leave about 1/2 inch of space on top for expansion) and insert wooden sticks. PRO TIP: Covering the popsicles molds with foil before inserting wooden sticks helps keep them in place. Freeze for at least six hours or overnight.
Enjoy. Unmold paletas by running hot water over the outside of the molds for a few seconds. Serve and enjoy immediately!
A Note from Lola
TO MAKE MEXICAN CHOCOLATE ICE CREAM
I use the same mixture to make my Mexican chocolate ice cream. The main difference is that for the ice cream, you would transfer the chilled mixture into an ice cream maker and churn it according to the manufacturer's instructions. Then store it in an airtight container and chill it in the freezer for at least four hours before serving.
FREEZING INSTRUCTIONS
Store popsicles in the coldest part of your freezer and enjoy within one month to avoid freezer burn.
