Preheat the oven to 375° F. You will need two jelly roll pans or you can bake the cakes one at a time (I did the latter). Grease the pan then lay a sheet of parchment on top and grease and flour the parchment paper.

Beat eggs, spices, salt, vanilla and granulated sugar in a large mixing bowl until light, fluffy and thick.

Add the pumpkin puree and beat to combine. Add the flour and leavening (baking soda and baking powder) and briefly beat, to just combine.

Spread half of the batter evenly into the prepared pan (spread the other half into your second jelly roll pan or reserve it until the first is out of the oven).

Bake the first cake until the top of the cake springs back when touched, about 15 minutes.

When the cake is done baking, sprinkle powdered sugar over the top, generously. Cover it with a flour sack or large, thin kitchen towel and then carefully overturn the cake onto the towel, ensuring that there is a border of towel around the cake.

Peel off the parchment paper and dust the cake with a thin layer of powdered sugar. Fold the towel on the shorter side over the cake then gently and carefully roll it up. Tuck the towel around the cake and leave to cool. If you only have one jelly pan, clean it and bake the other cake now, following the same steps.

When both cakes are completely cool (after at least an hour), make the whipped cream:

In a food processor, add the softened cream cheese, the vanilla and salt and run it on low until mixed. Add the heavy cream and powdered sugar and run the processor until the mix is thickened, keeping a close eye on it.

Unroll the cakes and spread some of the cream cheese whipped cream on each cake. Slice them in half, horizontally so you have two long strips of cake. You will have four cake strips.

Roll one of the four cakes into a log. Take a second cake strip and wrap it around the log, starting from where the first ended. Repeat with the second and third cakes until you have what looks like the inside of a tree. Spread the remaining whipped cream all around and over the cakes. Decorate as you please.
