In a food processor, combine the chopped dates, honey, chia seeds, ground flax seeds, and a pinch of salt. Pulse until the mixture is smooth and evenly blended. The mixture should be soft enough to stir; if it feels too thick or dry, I like to add another tablespoon or two of honey for easier mixing.
Transfer the blended date mixture to a large bowl. Stir in the old-fashioned oats, shelled pistachios, dried cranberries, and white chocolate chips (if using) until everything is thoroughly combined and evenly distributed.
Cover the bowl with plastic wrap or a lid and refrigerate the energy bite mixture for at least 30 minutes. This helps the mixture firm up and makes it much easier to shape later.
Once the mixture has chilled, use a spoon or cookie scoop to portion it out. Roll each portion into balls about 1 inch in diameter, or press the mixture into a parchment-lined baking pan to create bars, then slice as desired. I like to gently compress the balls with my hands to make them more compact and hold together better.
Transfer the finished energy bites or bars into an airtight container and store them in the refrigerator. They’ll stay fresh and keep their shape for up to 2 weeks. I always keep mine chilled for the best texture and easy snacking.
