Does white chocolate have caffeine?
White chocolate does not contain caffeine, since those ingredients that make chocolate dark are absent in the white chocolate production process. One may still get sugar rush from white chocolate, but it will be absent the caffeine in chocolate of the milk or dark varieties. See the "Related Links" section below for more information about caffeine in chocolate.
Yes, chocolate bars have a small amount of caffeine in them. For example: 1 oz of Dark Chocolate will have about 12 mg of caffeine. 1 bar of Dark Chocolate will have about 70 mg of caffeine. 1.55 oz of Milk Chocolate will have 9 mg of caffeine. 100 grams of Milk Chocolate will have about 20 mg of caffeine. Hershey's chocolate bars have about 9mg of caffeine in them.
This depends on how the hot chocolate is prepared (using natural cocoa powder or a hot chocolate mix, melting dark, milk or even white chocolate in it). It is possible to increase the amount of caffeine by adding coffee to your hot chocolate or by making it based on black tea. In general, cocoa contains less caffeine than coffee or even tea.
White chocolate is not really chocolate. It contains cocoa fat, and sugar, I think some type of shortening and artificial flavors. That's about it. White chocolate is made from sugar, cocoa butter, and milk. It is based on cocoa butter instead of cocoa solids, which gives it the "ivory" or "pale yellow" appearance it has. White chocolate doesn't taste like milk chocolate or dark chocolate because it does not contain caffeine.
