Peanut butter, a creamy or crunchy spread made from ground roasted peanuts, is a versatile ingredient that can add a rich, nutty flavor to various dishes and beverages. In the context of cocktails, peanut butter is often used to introduce a unique, savory element that pairs well with both sweet and salty flavors. Its thick, smooth texture can create a luscious mouthfeel, enhancing the overall drinking experience.

When used in alcohol-based drinks, peanut butter is typically incorporated into cocktails that benefit from its distinct taste and texture. For example, it can be blended into creamy concoctions like peanut butter milkshakes with a boozy twist or used in innovative cocktails such as a peanut butter whiskey sour. The natural oils in peanut butter can also complement the flavors of spirits like whiskey or rum, creating a harmonious balance that appeals to adventurous palates.
