Preheat to 350°F. Line a 10x15-inch jelly roll pan with parchment paper and lightly grease it. Lay out a clean kitchen towel and dust it generously with powdered sugar.
2️⃣ Make the pumpkin sponge:
In a bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger.
In a separate bowl, beat eggs and sugar until thick and pale. Beat in pumpkin puree. Gently fold in dry ingredients just until combined.
3️⃣ Bake:
Pour batter into prepared pan and smooth evenly. Bake 12–14 minutes, until the cake springs back when lightly touched.
4️⃣ Roll it up:
Immediately invert warm cake onto the sugared towel. Peel off parchment. Starting at the short end, roll the cake up with the towel inside. Cool completely.
5️⃣ Make the filling:
Beat cream cheese, powdered sugar, butter, and vanilla until smooth and creamy.
6️⃣ Assemble:
Carefully unroll the cooled cake. Spread filling evenly over the surface. Roll it back up (without towel). Wrap in plastic wrap and chill at least 1 hour.
7️⃣ Serve:
Dust with more powdered sugar, slice, and watch it disappear.
Notes
Make ahead: This actually tastes better the next day!
No jelly roll pan? Use a rimmed baking sheet, but adjust baking time slightly.
