In a standing mixer with paddle, cream butter and sugar until light and fluffy. Split and scrape vanilla bean into the mixture. *Do not use pod - only the seeds. Mix well and add whites and flour. Mix well and chill covered with plastic wrap, preferably overnight. *Use pod for compote.
Combine all ingredients in a heavy bottomed saucepan. Bring to a boil. Reduce heat and simmer 5 to 8 minutes. Remove from heat and let cool in pan. Remove all fruit and reduce sauce until syrup-like. Combine with fruit. Remove pod and set aside until ready to assemble.
Baking: Spread about 1 teaspoon cold tuille batter thinly over stencils (professional or homemade) on greased back of cookie sheet. Place tuiles in 350 degree F oven. Tuiles will spread and cook rapidly. Therefore, test a few, one at a time, for appropriate thinness of batter and length of cooking time. If tuiles have spread too much, reduce amount of batter and make sure batter is spread evenly and thinly. Tuiles should be removed from oven when slightly golden. Let set for a few seconds on sheet before removing to rack for cooling.
Assemble Napoleon by layering tuiles and fruit compote. Top with ice cream, frozen yogurt, or whipped cream.
