Protein 1g · Carbs 2.9g · Fat 0.7g
Unsweetened cocoa powder is a keto baker's best friend and a mineral powerhouse, delivering an extraordinary 499 mg of magnesium (119% DV) and 1524 mg of potassium per 100 g — among the highest of any food. With 228 kcal, 19.6 g of protein, and 13.7 g of fat per 100 g, it packs serious nutrition into every tablespoon. Despite 57.9 g of total carbs, a remarkable 37.0 g is fiber, leaving about 20.9 g of net carbs per 100 g — but since a tablespoon is only 5 g, that is just about 1 g of net carbs per serving. It is also exceptionally rich in manganese (3.837 mg, 167% DV) and contains theobromine, a natural stimulant milder than caffeine. Cocoa flavanols are powerful antioxidants linked to cardiovascular benefits. One tablespoon of cocoa powder (5 g) provides about 11 kcal and is the typical serving for baking or drinks. Here is everything you need to know about cocoa powder calories and macros, based on USDA data. Cocoa powder contains only about 3% water by weight.

Variations
Unsweetened (default)
228 kcal per 100 g. Pure cocoa powder with no sugar added. The standard form for keto baking — makes brownies, chocolate mousse, fat bombs, and hot chocolate. Rich in magnesium (499 mg, 119% DV), potassium (1524 mg), and manganese (3.8 mg, 167% DV). Contains theobromine for mild, sustained energy. Intense bitter chocolate flavor that pairs perfectly with keto sweeteners.
Dutch process (alkalized)
Similar calories to unsweetened (~228 kcal per 100 g). Alkali-processed for a milder, less acidic flavor and darker color. Slightly lower flavanol content than natural cocoa due to the alkalization process, but still a good source of minerals. Preferred in many European-style recipes. Works better with baking powder (which needs acid from elsewhere). The darker color makes visually striking baked goods.
Hot cocoa mix (reference)
Approximately 400 kcal per 100 g — pre-mixed with sugar, powdered milk, and sometimes vegetable oil. Contains 60-70 g sugar per 100 g. NOT keto-friendly. A single serving packet (28 g) has about 110 kcal and 20 g sugar. If you want hot chocolate on keto, always use pure unsweetened cocoa powder with heavy cream and a keto sweetener instead.
Dietary Perspectives
For Weight Loss
Cocoa powder is remarkably low-calorie per serving — one tablespoon (5 g) has only 11 kcal. It makes rich-tasting desserts with minimal calories. Mix 1-2 tablespoons with unsweetened almond milk for a low-calorie hot chocolate (~30 kcal). The intense chocolate flavor satisfies cravings without sugar. Add to Greek yogurt or protein shakes for a chocolate boost without significant calories. The high fiber (37 g per 100 g) promotes satiety. Weigh your portion carefully — cocoa is calorie-dense per 100 g (228 kcal) but you use so little per serving that it fits any calorie budget.
For Athletic Performance
Cocoa powder provides exceptional magnesium (499 mg per 100 g, 119% DV), which prevents cramps and supports muscle recovery — one of THE highest magnesium foods available. Theobromine provides mild, sustained stimulation without the jitters of caffeine. Flavanols improve blood flow and may enhance exercise performance. Add 1-2 tablespoons to protein shakes for chocolate flavor plus a mineral boost. Potassium (1524 mg per 100 g) supports electrolyte balance during intense training. At only 11 kcal per tablespoon, it adds negligible calories to your post-workout nutrition.
For Keto
Cocoa powder is an essential keto baking ingredient — only about 1 g net carbs per tablespoon (5 g). It makes keto brownies, chocolate mousse, fat bombs, and hot chocolate. Mix with heavy cream and a keto sweetener for instant keto chocolate. The high fiber (37 g per 100 g) means most carbs do not count. The outstanding magnesium (499 mg per 100 g, 119% DV) is especially valuable on keto, where magnesium deficiency is common and can cause cramps, fatigue, and headaches. Potassium (1524 mg per 100 g) is another electrolyte often lacking on keto. One tablespoon in your morning coffee or smoothie provides minerals without breaking ketosis. Pair with coconut oil or butter for a keto hot chocolate that is both satisfying and mineral-rich.
Frequently Asked Questions
How many calories are in cocoa powder?
One tablespoon of unsweetened cocoa powder (5 g) contains approximately 11 calories. Per 100 g, cocoa powder has 228 calories. A quarter cup (22 g) has about 50 calories. It is surprisingly low-calorie per serving because you use so little — most recipes call for just 1-2 tablespoons. Compared to dark chocolate (598 kcal per 100 g), cocoa powder delivers intense chocolate flavor at a fraction of the calories.
Is cocoa powder keto-friendly?
Yes, cocoa powder is an essential keto baking ingredient. Per tablespoon (5 g), it has only about 1 g of net carbs — truly negligible. While per 100 g it shows 57.9 g total carbs, 37.0 g is fiber, and you never use 100 g at once. It is perfect for keto brownies, chocolate mousse, fat bombs, and hot chocolate. Mix with heavy cream and a keto sweetener for instant keto chocolate. The high fiber (37 g per 100 g) means most carbs do not count. The outstanding magnesium (499 mg per 100 g, often lacking on keto) makes it doubly beneficial.
Is cocoa powder healthy?
Cocoa powder is exceptionally nutrient-dense. It is one of THE highest magnesium foods (499 mg per 100 g, 119% DV), which prevents cramps, supports heart rhythm, and aids muscle recovery. Potassium is massive at 1524 mg per 100 g. Manganese is extraordinary at 3.837 mg (167% DV), supporting bone health and metabolism. Cocoa is rich in flavanols — powerful antioxidants linked to improved blood flow, lower blood pressure, and cardiovascular health. It contains zero cholesterol and zero vitamin C.
Cocoa vs cacao — what is the difference?
Cacao is raw and less processed, retaining more flavanols and antioxidants. Cocoa is roasted at higher temperatures, giving it a milder, more familiar chocolate flavor but slightly fewer antioxidants. Nutritionally they are very similar — both have comparable calories, protein, fat, and mineral content. Both are keto-friendly. For maximum antioxidant benefit, choose cacao. For easier baking and milder taste, choose cocoa. The calorie and macro difference is negligible.
Dutch process vs natural cocoa — what is the difference?
Dutch process cocoa is alkali-treated, resulting in a darker color, milder flavor, and lower acidity. Natural cocoa is more acidic, lighter in color, and retains more flavanols. Dutch process works better with baking powder (which needs acid elsewhere), while natural cocoa pairs with baking soda (which needs acid from the cocoa). For keto baking without leavening, both work equally well. Calorie and macro content are virtually identical.
How much cocoa powder per day?
One to two tablespoons (5-10 g) per day is a good daily amount. This provides a significant dose of magnesium (25-50 mg per tablespoon) and flavanols without excess calories (11-22 kcal). More than 3 tablespoons may cause digestive discomfort from the very high fiber content and theobromine (a mild stimulant). Theobromine can also cause headaches in sensitive individuals at high doses. Space consumption away from bedtime as theobromine may interfere with sleep.
