Spreading peanut butter over an apple makes for a delicious afternoon snack, but it's not without some annoyances. Some varieties of peanut butter separate easily — even after you've mixed it up — leaving a layer of oil at the top of the jar when you're ready to dig in. Luckily, a simple storage hack can help you enjoy a more evenly incorporated nut butter that’s easy to smear on practically any of your favorite foods. Keep reading to learn what causes peanut butter to separate and how to avoid it in seconds!

Why peanut butter may appear oily

As annoying as it can be to deal with, the layer of oil on top of peanut butter is a good way to tell how natural it is. Most natural peanut butters contain only peanuts and possibly some salt. Business Insider notes that the oil comes from the process of grinding the nuts and is more likely to rise to the top of the jar while the solid mixture sits at the bottom. This doesn't happen with processed peanut butter because it has added oil, such as soybean, palm or cottonseed oil, which all mix together and prevent either one from floating to the top. These processed varieties may be less messy; however, natural peanut butter contains fewer ingredients that give you a more intense nutty flavor!

How to avoid oily peanut butter

Although natural peanut butter tends to separate, it's easy to reverse this effect. Storing the jar upside down in your pantry will cause the oil to settle at the opposite end of the jar. Once you're ready to use it, you can flip it to its normal position and the nut butter closest to the lid will be smooth, creamy and ready to spread without any excess oil in the way or the need to vigorously stir it beforehand. Be sure the lid is screwed on tightly so there are no spills when it sits upside down. To see how this hack works, watch the explainer below:

Bonus tip for perfectly smooth peanut butter

Another important tip is to keep the oil well-distributed throughout the jar by turning it every few days according to Real Simple. This prevents the oil from staying in one spot of the jar for long periods of time — providing you with ultra-spreadable peanut butter!
