Add 1 cup quick oats to a food processor and pulse for a few seconds until the oats are partially broken down. You’re looking for a coarse flour with some texture, not a fine powder.
Add 1/2 cup maple syrup, 1/2 cup natural peanut butter, 1/4 cup cocoa powder, 1 teaspoon vanilla extract, 1/2 teaspoon salt, and 2 tablespoons chia seeds to the food processor. Do not add the chocolate chips yet.
Process the mixture on low speed until everything is fully combined. You should hear the processor slow down as the mixture thickens and begins to form a large ball. If a ball hasn’t formed after about 30 seconds, add oats one tablespoon at a time and continue processing until the dough comes together.
Transfer the mixture to a medium bowl, then add 1/2 cup mini chocolate chips. Mix by hand with a sturdy spatula until evenly distributed. The dough will be thick. I use a slicing and folding motion to help work the chips in.
Scoop about one tablespoon of dough and roll it between your palms to form a ball. Place the bites on a tray or directly into your storage container.
For extra chocolate flavor, melt 1/2 cup chocolate chips with 1/2 teaspoon coconut oil. Finely chop peanuts if using. Dip each bite halfway into the melted chocolate, then roll in chopped peanuts. Place on parchment paper and let set in the fridge or freezer until firm.
