Combine dates, cashews, graham crackers, and maple syrup in a food processor. Break up the graham crackers into small pieces for easier blending. Process until ingredients combine and a ball is formed.
Remove the dough from the food processor. Place it in a bowl. If your dough is hot from the food processor, allow it to cool before adding the next ingredients.
With your clean hands, mix in mini marshmallows and broken pieces of the chocolate bar.
Roll into 18 - 20 balls. If your hands get sticky, wash them off and try again. Pro tip, cool your hands with ice before rolling them or spray your hands with a small amount of oil.
Store in the refrigerator or freezer.
