I do this with peanuts, but you can do it with any shelled and skinned nuts you like. Dump the nuts into a food processor and process until they are the consistency you like for nut butter. So, I am using peanuts, then when it is buttery enough, I throw in a handful of almonds and process until it’s chunky. Good stuff. It’s fun to try different nut combos here, with the “base” butter being peanut, almond, or cashew and putting unexpected nuts in for the chunks like: pecans, hazelnuts, almonds, walnuts, or black walnuts!
