Nut butter is a creamy paste made from ground nuts such as peanuts, almonds, cashews or hazelnuts. It has a creamy to slightly thicker texture and a rich, nutty flavor. Nut butter is often used as a spread on bread, in smoothies, baking recipes or as a dip for fruit and snacks. It is popular for its combination of flavor, protein and healthy fats, and comes in both plain and sweetened or salted varieties.
