Wash and peel your pumpkin.
Roast, Steam or boil for 20-25 minutes until soft.
Place in a bowl and mash using a fork or potato masher until smooth. (If you steamed or boiled, place in a sieve to drain some of the liquid it absorbed while cooking.)
Meanwhile, preheat oven to 180°C, brush an 8x4-inch loaf pan with butter or oil. Set aside.
In a bowl, mix together flour, pumpkin spice, baking powder, baking soda and salt, set aside.
In another bowl, whisk sugar, oil and egg, until smooth.
Stir in the pumpkin puree until well combined.
Add dry ingredients to the pumpkin and mix gently until just combined.
Fill the loaf pans up to two-thirds full.
Bake for 65-75 minutes until a skewer inserted in the middle, comes out clean.
Cool in the pan for 5 minutes then remove and cool completely on a wire rack.
