Pumpkin lovers will find this soft, firm, and sweet dessert an absolute treat.
Baking a sponge cake requires precise surface area to depth ratios, meaning you cannot easily halve this batter in a standard 10x15-inch jelly roll pan without the layer turning out too thin and overbaking. Doubling the recipe similarly demands a second baking sheet rather than overcrowding the oven, since excess moisture from the pumpkin puree prevents proper rising. Cotton tea towels work effectively for thermal regulation during the initial shaping phase, whereas textured terry cloth leaves unwanted lint embedded in the delicate exterior crumb.
Cream cheese fillings require fully softened butter beaten alongside confectioners' sugar to prevent a grainy mouthfeel. Chilling the finished dessert wrapped tightly in plastic wrap for at least two hours firms the structure, allowing clean slices through the spiral center. Strong black coffee or unsweetened spiced tea cuts through the rich butterfat and dense sweetness of the cream cheese filling.
