                                According to the United States Department of Agriculture (USDA), a 1-ounce serving of 70-85% cacao dark chocolate contains approximately 22.7 mg of caffeine, significantly more than the 5.6 mg found in a 1-ounce serving of milk chocolate. Understanding which has more caffeine, light or dark chocolate, hinges on their different concentrations of cocoa solids.
