Optional mix-ins: chopped walnuts, raisins and chia seeds are some of my favorites. Note: I use organic shredded coconut, Jif Naturals Peanut Butter, Ghirardelli Dark Chocolate Chips and homemade vanilla from beans purchased at https://www.beanilla.com/ We love to make our own vanilla as we enjoy the taste of homemade versus store bought. Plus, it's SO easy to make your own. Lastly, these energy bites are not only delicious, but easy and fun for kids to make. Our grandson named these "cookie balls" which seemed fitting and stuck. Other people know them as Energy Bites. They are the perfect little bite size snack to enjoy as a mid-afternoon pick-me-up, when your having a chocolate craving, to pack in your hiking pack/picnic or anywhere you would like to enjoy them!
