Preheat oven to 350 degrees.

Butter the bottom and sides of a 9 x 13 inch cake pan.

In a large bowl combine the pumpkin, evaporated milk, sugar, eggs and pumpkin pie spice. Whisk until combined.

Pour mixture into your buttered pan.

Sprinkle the cake mix over top the pumpkin as evenly as possible.

Sprinkle on the nuts & toffee pieces.

Pour melted butter evenly over the top of the cake.

Bake for 45-50 minutes. You want the edges to be browned & the center to be set.

Serve warm with a scoop (or 2) of vanilla ice cream.
