A yummy mix of crushed cookies and peanut butter cereal add sweet crunch to these fun ice cream bars.
Line a small baking sheet with parchment paper, wax paper or aluminum foil and set aside.
Place the cookies and cereal in a resealable plastic bag and gently crush with a rolling pin or skillet until everything is crushed and mostly gravel-sized (or crush toppings in a food processor). Place the toppings mixture in a large, shallow plate or baking dish.
Working with one ice cream bar at a time, pour the hardening ice cream sauce all over a bar. Use a butter knife to spread the sauce to fully coat. Lay the bar on the plate with the toppings, pressing gently to adhere. Flip the bar over and continue pressing into the toppings to fully cover the bar.
Place on the prepared baking sheet and immediately place in the freezer. Continue with the remaining bars and toppings. Freeze the coated bars for at least 10 minutes before serving.
