In a food processor, combine the chickpeas, almond butter, honey or maple syrup, and oats. Blend until smooth, about 1-2 minutes.

Line an 8x8-inch square dish with parchment paper. Spoon the cookie dough mixture into the dish and press down firmly to create an even layer, about half an inch thick.

In a mixing bowl, combine rolled oats with chopped almonds, cashews, and any additional flavors. Stir the mixture well.

Sprinkle the granola mixture over the cookie dough layer. Press gently to adhere.

Cover the dish and freeze for at least one hour to firm up the bars.

Remove from the freezer, lift out using parchment paper, and slice into squares or rectangles.
