A happy compromise between an energy bar and a decadent dessert, these crispy, chewy, sweet squares are delightful and can be enjoyed however you prefer.
In a food processor, puree the dates and the raisins until smooth, 20 to 30 seconds. Add the walnuts and the sesame seeds, and process until combined, 10 to 20 seconds.
Pulse in the chocolate chips and then the cereal. In between additions, use a spatula or a wooden spoon to break up the ball and to incorporate the other ingredients.
Transfer the mixture to a silicon or glass 8 x 8-inch square dish, and press firmly and evenly into the dish. Cover and refrigerate until hardened, at least 1 hour.
Cut into bars and serve immediately or store in an airtight container in the refrigerator for up 4 to 5 days.
