In a large mixing bowl, combine almond butter, honey, vanilla extract, and sea salt. Stir until smooth. Add oats, chia seeds, and chocolate chips if using, mixing thoroughly.

Using clean hands or a cookie scoop, portion out mixture and roll into 1-inch balls. Place them onto a parchment-lined baking sheet or tray.

Refrigerate the energy balls for at least 30 minutes to firm up before serving.
