While looking for snack recipes to try for Mr. Wonderful, I found this one for protein balls/energy bites, made half a recipe as an experiment, and proceeded to eat most of them myself (not all at once, y'all). I love this recipe. It's easy and has everything you need in a little pick-me-up snack: protein (peanut butter and protein powder), a quick-releasing carb (maple syrup), and a slow-releasing carb (oatmeal). I also added 1/4 cup of mini chocolate chips, because... chocolate. They're delicious, and keep very well in the fridge. I used a small cookie scoop and got about a dozen and a half from a halved recipe. For me, one is usually enough if I'm feeling a bit crashy.
Enjoy!
