Toast the Walnuts: In a dry skillet set over medium heat, gently toast the walnut halves for 3–5 minutes, stirring frequently to prevent burning. Remove from heat as soon as they become fragrant and let them cool completely.
Create the Base: In a high-power food processor, combine the rinsed black beans, chopped dates, unsalted almond butter, and ground cinnamon. Process for 60–75 seconds, scraping down the sides of the bowl halfway through, until the mixture forms a thick, smooth, cohesive paste.
Incorporate Mix-Ins: Add the cooled walnuts, golden raisins, dried apricots, dried tart cherries, chia seeds, and ground flaxseed to the processor. Pulse in 10–12 short bursts. You want the nuts broken down and distributed, but the dough should remain chunky and textured, not pureed.
Portion the Dough: Using a tablespoon or small cookie scoop, divide the mixture into 20 equal portions.
Shape and Coat: Roll each portion firmly between your palms to form a smooth ball. Place the toasted coconut in a small shallow dish. Lightly roll each ball in the coconut, pressing gently to apply a thin, even dusting.
Chill: Arrange the bites on a parchment-lined baking sheet or in a container. Refrigerate for at least 10 minutes to allow them to firm up before serving.
