What do you do when 2,000 people are coming over for dessert?

That was the challenge facing Chef Mark Bennison when he was asked to prepare the sweet ending to Zoobilee, the annual fundraiser for the Roger Williams Park Zoo in Providence, R.I.Food from two dozen local restaurants was offered to the massive crowd that came to "feast with the beasts." But it was Chef Bennison's 4,000 mini-pastries and 40 cakes that dazzled the partygoers who meandered through the zoo for a glimpse or two of the elephants and giraffes, monkeys and polar bears.

Bennison is executive pastry chef of the Radisson Airport Hotel, an education facility of Johnson & Wales University. So he has all the space, equipment and manpower needed to accomplish such a daunting task.

"I always look for the `wow' factor," Bennison said. "When people look at one of my desserts, I want them to say `wow' before digging in to eat."

At the Radisson, Bennison's desserts change daily, and three specials are offered every day. Bennison says he gets his dessert ideas from reading about what other pastry chefs are doing and from experimenting.

Bennison's day begins at the hotel at 5 a.m. For the greater part of each day, he works with eight to 12 baking and pastry arts students who are hungry for hands-on experience in the kitchen. "They learn how to make everything from bread to ice cream," he explained.

Plain and simple ice cream is this pastry chef's own favorite dessert, although he produces fancier creations for other people.

"It's a little odd, but I just like to make desserts - I'm not much of a dessert eater except for ice cream," Bennison said.

From Bennison's recipe collection, here are two that feature ice cream and are sure to be a big hit with youngsters of all ages.
