Whether you've got a long day of work, school, or adventuring ahead, the key to sustaining your energy through the day is a healthy snack! While trail mix or fruit is definitely a good choice, you might find yourself reaching for a protein bar or energy balls to fill that midday stomach rumble (or sweet tooth).

And while there are a bunch of really good store-bought options out there, if you find that you like making your own snacks at home, a DIY option might be more up your alley!

With that said, we've put together a list of some of our favorite protein bars and balls to keep you energized through your busy day, adventure, or workout.

Chocolate Matcha Energy Balls

If you're looking for a protein ball that will fill you up and put a little pep in your step, consider these chocolate matcha energy balls!

Ingredients

1/2 cup raw cashews
1/4 cup raw walnuts
1 cup pitted dates
1 tablespoon maple syrup or honey
2 tablespoons unsweetened cocoa
1 tablespoon plus 1 teaspoon matcha, divided
Pinch of salt

Directions

Place cashews and walnuts in the food processor and grind the nuts to a fine mince, then scrape them to the center of the container. Add the dates, maple syrup or honey, cocoa, 1 tablespoon matcha and salt. Process until the dates form a thick paste and the mixture holds together if you squeeze a bit of it.
Scoop out a tablespoon of the mixture, form into a ball and place into a medium bowl; repeat until all of the mixture has been used. Use a wire mesh strainer to sift the remaining matcha over the balls. Roll the balls around to coat. Store, tightly wrapped, in the refrigerator for up to a month.
