Often, the birthday foods that kids care about the most are cake and ice cream. They could take or leave everything else. For the birthday kid with a certified sweet tooth, an ice cream sundae bar is a cool concept that doesn't cost much. Pick up bulk-sized ice cream tubs; those with vanilla, chocolate and strawberry will suit most flavor preferences. Chocolate and caramel syrup are must-haves. You could also chop up some berries, peaches and pineapple for a healthier touch. Crumble the birthday kid's favorite cookies and candy bars for additional toppings. Don't worry about buying ice cream cones; bowls and spoons are easier to manage. Guests can top their ice cream however they choose, but adults should handle the scooping and syrup squirting for younger groups.
