For a truly authentic King Cake experience, tuck a whole almond or other nut into the filling before baking. Whoever finds the almond in their slice is said to have good luck! Be sure to prick the puff pastry thoroughly with a fork to prevent it from puffing up too much during baking. Feel free to experiment with different extracts in the cream cheese glaze, such as vanilla, almond, or even a hint of rum. Store leftover tart in an airtight container at room temperature for up to 2 days.
