Method
Prep and bake the crust
- Preheat the oven to 350F and grease a 9x13 pan with a light coating so the crust releases cleanly.
- Combine yellow cake mix, melted butter, and egg, then press the mixture into the greased pan in an even layer.
- Bake for 10 minutes at 350F until set at the edges, then remove the pan while you mix the filling.
Make and add the pumpkin filling
- Whisk pumpkin puree, eggs, granulated sugar, evaporated milk, pumpkin pie spice, cinnamon, ginger, and salt until smooth and uniform.
- Pour the filling over the warm baked crust so it spreads evenly to the corners.
Top and finish baking
- Combine reserved yellow cake mix, sugar, cold butter, and cinnamon until crumbly, then scatter the crumbs evenly over the filling.
- Bake for 40-45 minutes at 350F until the topping is golden and the center is set (no wet jiggle).
Cool and serve
- Cool the pan completely to help the filling fully firm up for neat square cuts.
- Cut into squares and serve with whipped cream.
Notes
Pro tip: for the best sliceable squares, cool all the way until the center no longer feels soft, then wipe the knife between cuts. Store covered in the refrigerator up to 4 days; freeze up to 2 months (thaw overnight in the fridge). For a dairy-reduced swap, use evaporated milk made from lactose-free or oat/soy-based substitutes if desired—texture may be slightly softer but still works.
