I go through phases of drinking coffee or tea. Right now it is coffee all the way. My favorite is a cinnamon mocha:
1 large cup of coffee
half and half
1 teaspoon of hersheys cocoa
2 packets of splenda or other sweetener
Mix well - the cocoa and the cinnamon can "float" to the top so you need to make sure that the coffee is well blended. The cinnamon brings out the flavor in the chocolate. Premium cinnamon also makes a huge difference - it is a little more costly but so worth it!
