A cup of hot chocolate provides approximately 10 mg of caffeine.
Notes on verification
WebMD states the ~10 mg figure verbatim, and independent USDA-linked sources bracket it (5-15 mg range), supporting the approximation. However, variability by recipe/brand (some report up to 25-36 mg) means the exact figure is approximate rather than precise.
