TSA: Is Peanut Butter a Liquid?
Yes. Here’s a fact that might stick to the roof of your mouth: peanut butter is considered a liquid according to the Transportation Security Administration (TSA). The 3-1-1 liquids rule applies to peanut butter, jelly and other nut butters. There are plenty of options on Amazon under 3.4 oz (I may receive a small commission if you make an Amazon purchase).
