Ghiradelli claims their dark chocolate has 20mg per oz and their milk chocolate has 6 mg per ounce. [1]

That would mean eating a standard 3.5oz/100g chocolate bar would have 70mg of caffeine for dark, or 21mg for milk.

While 3.5oz is a lot in a sitting, 70mg is equivalent to a smallish cup of coffee.
