                                One serving of a classic mille feuille can contain over 400 calories, a figure that is highly dependent on the recipe, portion size, and specific ingredients used. This decadent French pastry, known for its alternating layers of flaky puff pastry and rich crème pâtissière, is a treat with a surprisingly wide range of calorie counts.
