In a medium bowl, whisk together flour, baking soda, baking powder, salt and cinnamon. Set a side.
In the bowl of a stand mixer (or using a hand mixer), beat the pumpkin, applesauce, peanut butter, eggs and honey until well combined. With the mixer on low, slowly add the flour ingredients and mix just until combined.
Divide batter evenly between the two prepared pans and bake 30-40 minutes or until a toothpick inserted in the center comes out clean. Cool in pan for 10 minutes then invert cakes onto a wire rack to cool completely.
