Combine the nuts and oats in a food processor or blender (a small one works best) and pulse together until finely ground. Add the remaining ingredients, except chocolate chips for the flavors that add them, and pulse again until as smooth as you'd like. (I left mine a bit gritty for texture but if you'd rather, you should probably be able to get it completely pureed.) For the recipes using it, pour in chocolate chips/or chunks and pulse just to combine.
Roll the mixture into small bite-size balls (about 2 teaspoons each). If you're mixture seems a bit sticky or too soft, place it in the fridge to chill for about 30 minutes and it should be easier.
For the coconut ones, roll in extra coconut shreds and for the maple pecan top with some extra whole pecans. That's it, enjoy these on-the-go or as a quick snack whenever you need an energy boost or you have a late night craving! Store in an air-tight container at room temp for up to 1 week or in the fridge for as long as 2 or 3 weeks (though they'd probably last even longer).
