Add all ingredients to a very large bowl. Beat with a hand mixer on low speed until a thick mixture forms. Alternatively, combine everything in the bowl of a stand mixer and, using the paddle attachment, mix until a thick mixture forms.
If the mixture is too sticky: Add a few more tablespoons of oats and mix again. Keep in mind the oats will continue to absorb moisture as the mixture sits.If the mixture is too dry: Add a little more peanut butter or honey and mix again until it rolls easily.
Use a 1-tablespoon measuring spoon or a 1-1/2 tablespoon cookie scoop to portion the dough. Tightly roll into balls (see note 2). Place the rolled balls on a parchment-lined plate or tray and refrigerate for 30 minutes to 1 hour, or until firm. Transfer to an airtight container.

Notes
Note 1: If using salted peanut butter, you may want to reduce or omit the salt. If using table salt, use only a tiny pinch.Note 2: If using a cookie scoop, the dough can be packed firmly in the scoop and released onto a tray instead of rolling each ball.Storage: Store in an airtight container in the fridge for up to 1–2 weeks. To freeze, place on a lined tray until firm (1–2 hours), then transfer to an airtight container or bag. Freeze for up to 6 months. Enjoy slightly frozen or thawed.
