1-First Step: Prepare the pan and oven Preheat your oven to 350°F (175°C). Brush the bottom and sides of a 9×13-inch baking pan with some of the melted butter. This first layer of butter helps prevent sticking and also supports browning on the edges. Set out all ingredients before you open the phyllo. Phyllo dries out fast, so having everything ready keeps the process calm and easy. If your phyllo is still a bit stiff, let it thaw fully in the refrigerator overnight or on the counter for 2 to 3 hours.

2-Second Step: Handle the phyllo with care Unroll the phyllo pastry and trim it if needed so it fits your pan. Keep the sheets covered with a clean towel while you work so they do not dry out. If a sheet tears, do not worry. Just adjust it in the pan and keep going. Phyllo is forgiving when it is layered and buttered well. Fold two sheets of phyllo accordion-style and place them in the prepared pan. Repeat this process until the pan is filled. The folded layers create the airy texture that makes the dessert crisp and delicate after baking.

3-Third Step: Bake the pastry in stages Place the pan in the oven and bake for 10 minutes. This first bake helps the layers start to set and turn light golden. Remove the pan and drizzle the remaining melted butter over the pastry. Bake again for another 10 minutes. This second bake deepens the color and adds flavor. Do not reduce the butter, because it gives the best texture and helps the pastry crisp up properly.

4-Fourth Step: Mix the custard While the pastry bakes, whisk together the milk, heavy cream, sugar, eggs, and vanilla in a mixing bowl. Stir until smooth and fully blended. The custard should look creamy and even, with no streaks of egg showing. This mixture is what turns the baked phyllo into a soft, custardy dessert underneath the crisp top. Using 3% whole milk and heavy cream gives the richest texture, but you can use all milk if you want a lighter version.

5-Fifth Step: Pour and bake until golden Carefully pour the custard over the hot phyllo after the second bake. Make sure it spreads evenly across the pan and seeps into the layers. Return the pan to the oven and bake for 30 to 40 minutes, or until the top is golden and crispy. You want the custard to be set and the pastry to look deeply golden without becoming dry. If the top browns too quickly, loosely cover it with foil for the last part of baking.

6-Final Step: Finish with maple syrup and nuts As soon as the cake comes out of the oven, brush it with maple syrup while it is still hot. Use dark amber or dark grade B syrup for the richest maple flavor. Then sprinkle the finely chopped pecans or walnuts over the top. Let the cake cool before slicing and serving. This resting time helps the custard set and makes cleaner slices. The full recipe takes about 15 minutes to prep, 1 hour to cook, and 1 hour 15 minutes total.
