Step 3: Create the Cake
Combine all dry ingredients in a small bowl. This includes the flour, baking powder, baking soda, cinnamon, and salt.
Beat together the eggs in sugar in a large mixing bowl until thoroughly mixed and thick. Add the pumpkin, beat until mixed, and then stir in the flour mixture.
Pour the cake batter into the pre-prepared wax-lined jelly-roll pan and use a rubber spatula to evenly distribute the batter across the pan.
Bake the cake for 13-15 minutes. When the cake is done, it will spring back when you touch the top of it with your finger. You can also stick a toothpick into the cake and if it comes out clean, it also means its done.
Remove cake from oven and IMMEDIATELY move on to step 4.
