Whether you’re a crunchy fanatic or creamy connoisseur, natural nut butter is delicious—but the mess of stirring separated oil? Not so much. Enter: Grandpa Witmer’s Old-Fashioned Peanut Butter Mixer, a brilliant, no-splash solution that takes the struggle out of your snack ritual.
This cleverly simple mixer fits most 16-ounce peanut butter jars with 3-inch lids, creating a tight seal that lets you churn the separated oil back in without oily hands, spoons, or frustration. Just twist and stir—it’s satisfyingly smooth in seconds.
No batteries. No gadgets. Just smart design. Crafted in America with durable, BPA-free materials, Grandpa Witmer’s mixer uses a molded plastic knob and a strong mixing rod to power through even thick natural butters. It’s exactly the kind of tool your grandpa would’ve had—and it still works better than anything “smart.”
Once your jar is mixed to perfection, the handle removes easily, and the mixer cleans up in seconds. Just hand wash all parts in warm, soapy water—no fiddly components or special cleaning needed.
If you’ve ever opened a jar of natural peanut butter and wondered how to not spill oil everywhere, this tool was made for you. No more paper towels, ruined knives, or pre-mixing with a spoon (aka the oil volcano method).
Customers Promising Reviews: “Works well for healthy peanut butters where the oil tends to separate to the top while on the store shelf. This also makes a great little housewarming or wedding shower gift for others, and also for students who will be eating a lot of peanut butter in dorm rooms during late night study sessions, or for cooks who “have everything”.” – one voice in the crowd
“A great little gadget that does what is says; it stirs your peanut butter when it separates, and lets you avoid making a mess. It is easy to wash and store. I like the way the liner lets you clean off the stirrer when you pull it out of the lid.” –
