Strawberry-Almond Cream Napoleons

Heat oven to 400°F (205°C). Thaw folded pastry sheet 20 minutes. Open sheet and cut along folds to make three equal strips; halve each strip to make six rectangles. Space apart on baking sheet. Bake in center of oven about 15 minutes until well browned and baked through. Remove to rack to cool. Meanwhile, in bowl, whisk pudding mix, milk and extract 2 minutes; fold in whipped topping to blend thoroughly. Cover and refrigerate. Carefully split each piece of pastry in half horizontally. Cover bottom halves with almonds, then pudding mixture and sliced strawberries, dividing equally. Cover with pastry tops. Dust with powdered sugar. If desired, serve with Strawberry Sauce (recipe below). To serve, divide sauce among 6 plates; top each with Napoleon.
