Cocoa beans contain caffeine, so the higher the percentage of cocoa in a chocolate bar, the higher its caffeine content. Likewise for coffee: Ounce for ounce, the more diluted the coffee drink, the less caffeine.
One of these plants is the cocoa tree, where the caffeine is found in the seeds (called cocoa beans). Cocoa beans are similar in size and shape to almonds, and they grow inside cocoa pods. The hard cocoa pod is about the size of a small Nerf football.
