Is Peanut Butter High in Protein?

Somewhat, with a real caveat. Peanut butter has genuine protein, about 7g per 2-tablespoon serving, but it’s not protein-dense the way meat, dairy, or even tofu are. It’s carrying a lot of fat and calories alongside that protein.

The actual numbers

Per 100 grams, peanut butter has about 22g of protein, which sounds strong until you look at what comes with it: roughly 51g of fat and nearly 600 calories in that same 100 grams. A typical 2-tablespoon serving (about 32g) works out to roughly 7g of protein, 16g of fat, and 190 calories. That’s a real but modest protein contribution riding on a much bigger calorie number.

How it compares

Gram for gram, peanut butter actually carries more protein than firm tofu, eggs, or Greek yogurt: about 22g per 100 grams, against about 9 to 11g for typical firm tofu, 13g for eggs, and 10g for plain nonfat Greek yogurt. Only chicken breast, at about 31g, clearly beats it. Where peanut butter falls behind is calories. It costs about 27 calories per gram of protein, against about 12 for eggs, 8 for firm tofu, 6 for Greek yogurt, and 5 for chicken breast. That doesn’t make it a bad food, it makes it a flavor and fat source that happens to bring some protein along, more than a dedicated protein source on its own.

Where it actually earns a place

Peanut butter works best paired with something more protein-dense, not standing in for it. In the peanut butter cookies on this site, the real protein number comes from eggs and protein powder; peanut butter is there for flavor and moisture, not as the protein backbone of the recipe.

FAQ

Is powdered peanut butter higher in protein than regular peanut butter?

Not per serving, slightly less if anything. PB2, the common brand, lists 6g of protein and 1.5g of fat per 2 tablespoons, and says it has almost 70% fewer calories than traditional peanut butter. Regular peanut butter carries 7g of protein, 16g of fat, and 190 calories in the same 2 tablespoons. Powdered isn’t a protein upgrade, it’s a calorie and fat cut that keeps most of the protein.
