Every 100 kcal of peanut flour brings 7.9 g of protein. On that measure it ranks 3rd of the 54 legumes in this database and 310th of all 796 foods on the site. Measured by weight instead, its 33.8 g per 100 g ranks 1st in its group.
Protein accounts for roughly 32% of the calories in peanut flour, making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Weight for weight, peanut flour has 1.5 g of protein for each gram of fat (33.8 g against 21.9 g per 100 g).
Set against refried beans, another legume entry in the database, a serving carries about 1.3 g less protein (refried beans has 6.4 g per 1/2 cup).
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 quoted here is measured by volume at 15 g, and it covers about 10% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
33.8 g. The 1/4 cup serving used on this page weighs 15 g and so carries 5.1 g.
How much protein do you get per 100 calories of peanut flour?
7.9 g. That figure divides its 33.8 g of protein per 100 g by its 428 kcal per 100 g, so it does not depend on serving size.
Is the protein in peanut flour complete?
No. On its own, the protein in peanut flour is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of peanut flour?
About 10%. One 1/4 cup serving has 5.1 g, and the FDA Daily Value for protein is 50 g.
