Caffeine in Chocolate vs Coffee: How Much Is in Each?
Share
A square of dark chocolate after dinner feels innocent next to an evening espresso. Is it? When you compare caffeine in chocolate vs coffee, the numbers are lopsided: an ounce (28 g) of 70 to 85 percent dark chocolate contains about 23 mg of caffeine, while the FDA puts a 12 oz cup of regular brewed coffee at 113 to 247 mg. Milk chocolate has far less, and white chocolate has essentially none.
That does not mean chocolate is caffeine-free. Eat enough dark chocolate and it adds up, and chocolate also contains theobromine, a related compound. Here are the numbers, worked examples and what they mean for an evening treat.
Key takeaways
- Dark chocolate (70 to 85% cacao): about 23 mg caffeine per ounce, or about 80 mg per 100 g.
- Milk chocolate: about 6 mg per ounce. White chocolate: essentially 0 mg.
- A 12 oz cup of brewed coffee: 113 to 247 mg (FDA).
- You would need about 5 oz (141 g) of very dark chocolate to match the low end of one 12 oz coffee.
- Chocolate is much richer in theobromine than in caffeine.

Caffeine in chocolate vs coffee: the numbers
The chocolate figures below match USDA nutrient data for standard chocolate types. Coffee and tea figures come from the US Food and Drug Administration.
| Food or drink | Serving | Caffeine (approx.) |
|---|---|---|
| Dark chocolate, 70 to 85% cacao | 1 oz (28 g) | 23 mg |
| Dark chocolate, 45 to 60% cacao | 1 oz (28 g) | 12 mg |
| Milk chocolate | 1 oz (28 g) | 6 mg |
| White chocolate | 1 oz (28 g) | 0 mg |
| Green tea | 12 oz (355 ml) | 37 mg |
| Black tea | 12 oz (355 ml) | 71 mg |
| Regular brewed coffee | 12 oz (355 ml) | 113 to 247 mg |
Per 100 g, very dark chocolate comes to about 80 mg of caffeine, mid-dark chocolate about 43 mg and milk chocolate about 20 mg. Real bars vary: cacao origin, recipe and cacao percentage all shift the number, so treat these as averages. One chocolate retailer reports tests of 75 percent bars from different origins ranging from about 18 mg to 42 mg per ounce.

Worked examples
To make the numbers concrete, here is how much chocolate it takes to equal one 12 oz cup of coffee at the FDA’s low (113 mg) and high (247 mg) ends.
| Chocolate | To match 113 mg | To match 247 mg |
|---|---|---|
| Dark, 70 to 85% | About 5 oz (141 g) | About 11 oz (309 g) |
| Dark, 45 to 60% | About 9 oz (263 g) | About 20 oz (574 g) |
| Milk chocolate | About 20 oz (572 g) | About 44 oz (1.25 kg) |
Example 1: the after-dinner square
Two squares of a 70 to 85 percent bar weigh roughly 10 to 15 g. At about 80 mg per 100 g, that is 8 to 12 mg of caffeine, far less than a single cup of coffee or even a cup of green tea.
Example 2: the movie-night bar
A whole 100 g bar of 70 to 85 percent dark chocolate gives about 80 mg. That is more than a 12 oz cup of black tea (71 mg) and getting close to the low end of a 12 oz coffee.
Example 3: the mocha
A mocha combines both. The coffee provides almost all the caffeine. The chocolate sauce or cocoa adds a small amount on top, depending on how much and how dark it is.
What about theobromine?
Chocolate’s main natural stimulant compound is not caffeine but theobromine. The two molecules are close chemical relatives. Cocoa contains a lot more theobromine than caffeine. USDA-based nutrient listings show roughly 227 mg of theobromine in an ounce of 70 to 85 percent dark chocolate, about ten times its caffeine.
If you are curious about the molecule itself, our article on the caffeine molecule explains its structure and why plants make it.
Why darker chocolate has more caffeine
Caffeine and theobromine come from the cocoa solids, the dark, non-fat part of the cocoa bean. The cacao percentage on a label counts cocoa solids plus cocoa butter.
- Dark chocolate: high cacao percentage, lots of cocoa solids, the most caffeine.
- Milk chocolate: lower cacao percentage diluted with milk and sugar, so much less caffeine.
- White chocolate: made with cocoa butter but no cocoa solids, so essentially no caffeine.
That is also why two bars at the same percentage can differ: one may use more cocoa butter and fewer solids than another.
Chocolate, coffee and sleep
For most adults, the FDA cites 400 mg of caffeine a day as an amount not generally associated with negative effects. A few squares of dark chocolate barely register against that, but if you are very sensitive to caffeine, eat a large dark bar late at night, or combine it with an evening coffee, the total can matter.
- Very sensitive? Choose milk chocolate in the evening, or white chocolate.
- Counting caffeine? Half of a 100 g bar of 70 to 85 percent chocolate is about 40 mg; a whole milk chocolate bar of the same size is about 20 mg.
- Pregnant or breastfeeding? EFSA advises up to 200 mg of caffeine per day, and chocolate counts toward it. Ask your doctor or midwife about your own limit.
Coffee and chocolate, together
If you love the combination, you can get chocolate flavor in your cup without any sugar. Our Mocha flavored coffee is medium-roast specialty grade Arabica infused with rich chocolate flavor, and Mexican Chocolate adds cinnamon and vanilla. For an evening cup with dark chocolate, our Peru Decaf is decaffeinated with the Swiss Water Process. Pairing ideas are in our guide to coffee and chocolate pairing.
Caffeine in chocolate vs coffee FAQ
Does chocolate have more caffeine than coffee?
No. Ounce for ounce of finished product, a cup of coffee has far more. You would need about 5 oz of very dark chocolate to match the low end of one 12 oz brewed coffee.
Can dark chocolate keep you awake?
A large amount of very dark chocolate late in the evening can add a meaningful dose for sensitive people. A square or two is a small amount.
Does hot chocolate have caffeine?
Yes, a little, from the cocoa. The amount depends on how much cocoa or chocolate is used; it is usually much less than coffee.
Is there caffeine in white chocolate?
Essentially none, because white chocolate contains cocoa butter but no cocoa solids.
