Frosting Recipe:
Add sweet cream and powder sugar in a large mixing bowl.
Mix on high until sweet cream and powder sugar is thoroughly mixed.
If it does not mix add the heavy whipping cream. (Again remember to be patient with the sweet cream and powder sugar.)
Check to see if the frosting can form and keep a stiff peak. If not add more powder sugar and mix until it can form and keep that stiff peak.
Using a pastry bag and a large tip frost the cooled cupcakes.
Sprinkle cinnamon on top of the freshly frosted cupcakes.
