Line a cookie sheet with aluminum foil.  Spray lightly with non-stick cooking spray. 

In a four cup, microwave safe glass measuring cup, stir together corn syrup and sugar until well combined. 

Cover tightly with a piece of plastic wrap. Cook in microwave on high power for four minutes.  Mixture should be boiling.    

Carefully remove plastic wrap and DISCARD the wrap.  Use a CLEAN spoon to stir the mixture well. Cover with a NEW piece of plastic wrap and place back into the microwave for four minutes more on high power. 

Carefully remove from microwave and remove plastic wrap.  Working quickly, use ANOTHER CLEAN SPOON, and stir in a few drops of food coloring, if desired.  Stir in the entire bottle of cinnamon oil flavoring.   

Immediately pour onto a foil lined cookie sheet.  Allow to cool completely until candy has hardened.  

Break hardened candy into bite sized pieces.  Immediately dredge in powdered sugar. Store in air tight container on the counter.  Do not refrigerate!
