Preheat your oven to 350 degrees Fahrenheit.
In a large mixing bowl, whisk together eggs and oil, then add pumpkin puree and sugar until smooth.
In another bowl, combine pudding mix, flour, baking powder, pumpkin spice, and baking soda. Whisk together.
Pour the dry mixture into the wet mixture and fold together until just combined.
Prepare your loaf pan by greasing it, then pour in the batter.
Bake for about 60 minutes until golden brown.
Allow to cool in the pan for 15-30 minutes before transferring to a wire rack.
