Preheat oven to 350℉.
Pour about a tablespoon of the melted butter into the bottom of the casserole dish and swirl the pan to coat the bottom and sides of the pan with the butter.
Pick up two sheets of phyllo dough with your hands and crinkle it into an accordion fold.
Place the folded sheets of dough into the buttered casserole dish.
Start on one end of the dish and continue until all the dough is fitted into the casserole dish.
Fluff the folds to make sure they are evenly spread out throughout the pan.
Bake for 5 minutes.
Remove cake from the oven and drizzle it with melted butter over the top of the phyllo dough into the folds.
Return to the oven and bake for another 5 minutes. Keep an eye on it so it doesn't burn.
Add milk, eggs, 1 cup sugar, vanilla, almond extract, cinnamon, nutmeg and allspice to a mixing bowl.
Whisk to combine the custard filling.
Remove cake dish from the oven and pour the custard evenly over the phyllo dough in-between the folds.
Tent dish with a piece of foil to prevent the dough from burning.
Bake cake for another 25-35 minutes, until golden brown and custard is set.
