Preheat oven to 375°F and place oven rack in the center of the oven. Line a 10x15 inch jelly roll baking pan with parchment paper, leaving about an inch on each end so you can easily lift the cake out after baking. Spray the parchment paper with non-stick spray.
In a large bowl, combine flour, pumpkin pie spice, cinnamon, salt, baking powder and baking soda.
In a separate bowl, whisk the eggs, coconut sugar and honey/maple syrup, until it’s well combined. Scrapping the sides and bottom of the bowl, as needed, to incorporate all of the honey/maple syrup. Mix in the vanilla, pumpkin, and lemon juice until combined.
Pour the wet ingredients into the dry and mix until combined. Do not over mix.
Pour the batter into the prepared pan. Spread the batter evenly. Bake for 14-16 minutes, you want the cake to spring back when lightly pressed.
Lay a damp thin linen towel flat on the counter. As soon as the cake is taken out of the oven, immediately invert it onto the towel. Peel off the parchment paper and slowly roll the cake with the towel, lengthwise. Place on a wire rack to cool.
