Preheat oven to 375 degrees F (190 degrees C). Grease and flour a 9×13 inch jelly roll pan or cookie sheet.
In a large bowl, mix together flour, sugar, baking soda, and pumpkin pie spice. Stir in pumpkin puree, eggs, and lemon juice. Pour mixture into prepared pan. Spread the mixture evenly.
Bake at 375 degrees F (190 degrees C) for 15 minutes.
Lay a damp linen towel on the counter, sprinkle it with confectioner’s sugar, and turn the cake onto the towel. Carefully roll the towel up (lengthwise) with the cake in it. Place the cake-in-towel on a cooling rack and let it cool for 30 minutes.
Make the filling: In a medium bowl, blend cream cheese, butter, vanilla, and sugar with a wooden spoon or electric mixer.
When the cake has cooled, about 30 minutes, unroll it and spread filling evenly onto it. Immediately re-roll (not in the towel this time), and wrap it with plastic wrap. Keep the cake refrigerated or freeze it for up to 2 weeks in aluminum foil. Cut the cake in slices just before serving and if desired, sprinkle with powdered sugar.
Notes
Notes: I used a jelly roll pan for this that I greased with butter and I used a small sifter to evenly flour it. This is the way to go as opposed to using a cooking spray and trying to sprinkle flour on with your hands.I had to add probably 3-4 minutes to my bake time to get it completely cooked through. Ovens will vary, you will need to check your cake layer and see if it needs any extra time.Recipe from Allrecipes.com
