It hurts my hand so fucking bad to do that, and yet it's completely worth it and I will never buy non-natural peanut butter again. Fuck that sugary garbage.

If there was some kind of unitasker tool specifically for painless mixing of natural peanut butter, I would probably pay like $30 for it without a second thought.

Edit: apparently people use paint mixer drill attachments for this and I'm definitely buying one now. Bourgeoisie decadence.
