One 9×13 sheet cake, warmly spiced and oil-based, finished with cream cheese frosting and cut into squares.
Cooling / resting: Cool completely in the pan before frosting
SAFETY NOTES
– This recipe contains eggs and dairy. Note both when serving guests with allergies.
– Use canned pumpkin puree, not pumpkin pie filling, which is already sweetened and spiced and will throw the recipe.
– Bake until the center springs back and a tester comes out with a few moist crumbs rather than wet batter.
– Refrigerate the frosted cake, as cream cheese frosting is dairy-based and should not be held at room temperature for more than 2 hours.
– Frosted, the cake keeps 5 days refrigerated. Unfrosted, it freezes well for a month wrapped tight.
– Wash hands and tools after handling raw eggs, and use eggs at room temperature without leaving them out longer than 2 hours.
