A typical 2 tbsp serving of cashew butter contains 5.6 grams of protein (17.6 g per 100 g), which makes it a moderate source of protein. That covers roughly 11% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 12% of the calories in cashew butter come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 31 nuts in the database, cashew butter ranks 9th by protein per serving, and 456th out of all 796 foods on the site. Set against cashews, another nut entry in the database, a serving carries about 0.5 g more protein (cashews has 5.1 g per 1 oz).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 32 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
