1-First Step: Get everything ready Preheat your oven to 350 degrees Fahrenheit. Grease a baking dish well so the pastry does not stick. Keep the phyllo pastry thawed and covered with a clean towel while you work, because it dries out quickly. Mix the melted butter, milk, heavy whipping cream, white granulated sugar, eggs, vanilla, and maple syrup in a bowl until smooth.

2-Second Step: Scrunch the phyllo Take the phyllo sheets and gently fold, scrunch, or accordion them into the baking dish. Do not worry about making it perfect. The uneven folds are what create the crinkle look. If a sheet tears, just keep going. This dessert is meant to look rustic and homemade.

3-Third Step: Add the butter mixture Slowly pour the custard mixture over the phyllo, making sure it gets into the folds and across the whole pan. Let it soak for a few minutes so the pastry absorbs some of the liquid. Sprinkle the finely chopped pecans or walnuts over the top. If you like a stronger nut flavor, lightly toast them first.

4-Fourth Step: Bake until golden Place the dish in the oven and bake for 35 to 40 minutes, or until the top is golden brown and crisp and the center looks set. If the top browns too fast, loosely cover it with foil for the last part of baking. Keep an eye on it during the final 10 minutes, since ovens can vary.

5-Final Step: Cool, slice, and serve Let the Maple Crinkle Cake cool for at least 15 to 20 minutes before slicing. This helps the filling settle, so the squares hold together better. Serve it warm with a small drizzle of extra maple syrup if you want more sweetness. It is also lovely with fresh fruit or a cup of coffee.
