Cooked quinoa is the trick here. It gives these energy bites a bit of chew that oats on their own never manage, and it stretches the peanut butter further so they are not quite as rich. No baking, no food processor, one bowl.
They set in the freezer in a couple of hours and keep there for weeks. This is what I hand over when someone announces they are starving fifteen minutes before dinner.

In a bowl, combine all ingredients and stir well.
Shape into round balls and place on parchment paper. Freeze for 2-3 hours and enjoy straight out of the freezer, allowing it to thaw for a few minutes to soften.
