Preheat the oven to 350°F.
Whisk the flour, cinnamon, baking powder, baking soda, and salt in a large bowl. Beat the eggs, sugars, pumpkin, and applesauce in another large bowl.
Gradually pour the dry ingredients into the wet ingredients and mix until just combined.
Pour the batter into an ungreased 9x13-inch baking pan and bake for 25–30 minutes or until set. Remove from the oven and let the pumpkin bars cool completely in the pan set on a wire rack.
