Preheat your oven to 375 degrees.
Prepare a 10x15 jelly roll pan by cutting a piece of parchment to fit the bottom of the pan. Lightly grease the pan, add the parchment, then lightly grease the parchment. Set the pan aside. (Non-stick spray works the best.)
Combine sugar, flour, baking soda, and pumpkin pie spice in a stand mixer or medium size bowl.
Add your remaining ingredients (pumpkin puree and eggs) and mix on low speed until combined.
Spread the cake batter evenly into the prepared jelly roll pan and bake for 15 minutes.
While the cake is baking, sprinkle a lint-free towel or napkin with powdered sugar with a small bakers sifter.
After removing from the oven, turn the warm cake out onto the prepared towel, remove the parchment paper, and roll the cake into the towel to cool completely on a wire rack.
