Over 500 million pounds of peanut butter are consumed in the United States every year, yet it contains no dairy. The reason why peanut butter is called butter is due to its spreadable consistency, which reminded early inventors of dairy butter, despite being a completely different product.

First introduced in the 1920s as the "Double Zero Bar," this classic American treat was rebranded to its shorter, more familiar name in 1934. The answer to why they call it a Zero bar is found in its early marketing, which sought to convey a sense of "icy coolness" to consumers.
