Set your oven to 350°F and prepare a 9x13-inch baking dish by greasing it lightly.
02 -
In a large bowl, whisk together the pumpkin purée, evaporated milk, sweetened condensed milk, eggs, pumpkin pie spice, and salt until fully combined and smooth.
03 -
Transfer the pumpkin mixture into the greased baking dish and even out the surface with a spatula.
04 -
Sprinkle the yellow cake mix evenly over the pumpkin layer, ensuring full coverage with no gaps.
05 -
Distribute the melted butter uniformly over the dry cake mix, moistening most of the surface to encourage even browning and crispiness.
06 -
Place the dish in the preheated oven and bake for 50 to 60 minutes until the top is golden brown and a toothpick inserted in the cake portion comes out clean while the custard beneath is slightly set; tent with foil during the last 10 to 15 minutes if browning too quickly.
07 -
Allow the dessert to rest for at least 30 minutes to firm up before slicing into squares. Serve warm or at room temperature with vanilla ice cream.
