Rijestevlaai is a creamy, rice pudding-based dessert that is popular in the Netherlands, Belgium, and Germany. The cake consists of a single crust that is topped with rice pudding. Rijstevlaai is best served cold, usually on Sundays, at birthdays, weddings, and retirement parties.
Vlaai, or flat pies, were originally invented by Germanic tribes who used to spread out the dough over a hot stone and top it with honey or fruit juice in order to make it more flavorful. As time went by, the dough became thinner, and the toppings larger, resulting in numerous flat pies we know and love today.
