Chocolate milk vs espresso: which has more caffeine?

Espresso has 63mg of caffeine per 1 oz shot and chocolate milk has 2.5mg per 8 oz glass, so the gap is about 25x. You would need roughly 25 servings of chocolate milk to match one 1 oz shot of espresso.

Chocolate milk vs espresso: the numbers

Both figures were checked against their source before this page went up: chocolate milk against Caffeine Informer (USDA SR Legacy 170879 agrees at 1mg per 100g) (source) and espresso against USDA FoodData Central (source). Brewed drinks and cocoa foods vary by batch, so published figures are averages rather than guarantees.

Where the caffeine in chocolate milk comes from

Cacao contains caffeine and theobromine, and the caffeine rides along into anything made with real cocoa solids. The more cocoa solids in the product, the more caffeine: unsweetened cocoa powder runs 230mg per 100g, dark chocolate at 70 to 85 percent cacao runs 80mg per 100g, and milk chocolate runs 20mg per 100g, all per USDA FoodData Central. Coffee-flavored desserts are a separate case, because the caffeine comes from actual coffee rather than cacao. Serving size does the rest of the work, which is why a mug and a square of chocolate can land in the same range.

If you want to control how much cacao goes in the mug, and therefore how much caffeine, start with plain powder instead of a pre-sweetened packet: browse unsweetened cocoa powder on Amazon.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
