A lower-calorie way to make Tarte au Sucre
Tarte au Sucre — with a thin oat crust and maple-custard filling
A shallow whole-grain tart carries a restrained maple-brown sugar custard with toasted oats, about 295 kcal per serving.
Control moisture first, build flavor through browning and aromatics, and use measured rich ingredients only where they are most noticeable. The finished tarte au sucre keeps its traditional shape and defining texture without a greasy or watery finish.
What changes—and what stays
From deep sugar pie with cream and butter often provides 450–600 kcal to 295 calories
Use a thinner oat crust, evaporated milk, and a shallow maple filling. Maple, dark brown sugar, toasted oat, vanilla, and a little salt create the familiar caramel flavor.
