Generic Cold Blended Coffee Drink

Make 2 cups of very strong coffee, or 1 cup of espresso plus 1 cup water.
Combine 2 cups milk, 2 tbsp cocoa powder, 1 tsp vanilla, and 2 tbsp of any flavor of syrup (chocolate, hazelnut, etc...or even honey!).
Add coffee to milk mixture.
Freeze for at least 3 hours, or up to 5. If frozen for less time, drink will be cold, but not icy. If frozen for more time, some thawing may be required before blending.
Remove from freezer, and place half of the mixture in a blender. Blend until smooth. Serve immediately to avoid separation.
