Frozen Chocolate Pizza

Yield: 1 14-inch pizza. Heat oven to 350 degrees. Pat cookie dough to cover a 14-inch round pizza pan. Bake until golden, 13 to 15 minutes. Cool completely. Scoop frozen yogurt onto cooled crust. Cover with waxed paper and press down with a metal spatula to spread yogurt into a flat, even layer. Leave waxed paper on top and place in freezer at least 1 hour. Remove from freezer and peel off waxed paper. Spread chocolate topping over, reserving a little bit of the topping for garnish. Peel and slice bananas over the pizza and drizzle remaining chocolate sauce over. Using a vegetable peeler, shave curls from the white chocolate and scatter over pizza. Serve at once.
