Does raw cacao contain caffeine?

Yes – in minuscule amounts. Just to give a little perspective: 

• 1 teaspoon of Cacao Powder = about 6.6mg of caffeine
• 1 teaspoon of Cacao Nibs = about 4.6mg of caffeine
• 1 cup of brewed coffee = 80-135mg of caffeine

While Cacao contains insignificant amounts of caffeine,  it does have high amounts of theobromine which is a gentle, mild stimulant with a longer-lasting and non-addictive effect, whereas the effect of caffeine is strong, fast acting, short lived and can be addictive. The stimulating effect of theobromine is much like waking up after a good night’s sleep.
