Chocolate Peanut Butter Mocha Powerballs (no-bake, vegan, gluten-free)

heaping 1/2 cup creamy peanut butter (I used storebought rather than homemade peanut butter)

light corn syrup, agave, brown rice syrup, or honey (not vegan)

unsweetened natural cocoa powder

tablespoons Instant Espresso Coffee Granules

vanilla extract (or bourbon or whiskey)

about 1 1/4 cups old-fashioned whole-rolled oats (use certified gluten-free if necessary; quick-cook oats may be substituted – start with 1 cup, and add more as needed)

sprinkles or cocoa powder for rolling, optional
