Yes, milk chocolate has caffeine, but not much: about 5.7mg per 1 oz (28.35g) bar, based on the USDA figure of 20mg per 100g (USDA FoodData Central, SR Legacy 167587). That is a quarter of the caffeine in the same weight of dark chocolate and about one seventeenth of an 8 oz cup of brewed coffee. You would need roughly 70.2 bars to reach the 400mg daily amount the FDA cites.

|---|---|---|---|---|
| Milk chocolate | 1 oz (28.35g) bar | 5.7mg | 20mg | 70.2 |
| Dark chocolate (70 to 85% cacao) | 1 oz (28.35g) square | 22.7mg | 80mg | 17.6 |
| Chocolate milk | 8 oz glass | 2.5mg | 1mg | 160 |
| Brewed coffee | 8 oz cup | 95mg | n/a | 4.2 |
Where the caffeine comes from
All chocolate caffeine comes from cocoa solids, and milk chocolate simply contains fewer of them. Milk, sugar, and cocoa butter make up most of the bar, which is why the USDA number lands at 20mg per 100g against 80mg for 70 to 85% cacao dark chocolate. The creamier the bar, the lower the dose.
A useful anchor: a standard 1.55 oz candy bar carries under 9mg, which is less caffeine than a single sip of most coffees. Parents asking whether a chocolate bar will wire a kid are really asking about the sugar.
