Preheat your oven to 325 and prep a loaf pan well. Using two methods works well- for example, grease and flour over the grease.
In a medium bowl, use a fork or a whisk to mix together the flour, baking soda, baking powder, ground cinnamon, cloves, ground ginger and allspice. Set this bowl aside.
Next, in a mixing bowl, blend together the oil with the sugar alternatives. Then beat in the eggs, one at a time. Lastly, stir in the water with the pumpkin puree and vanilla extract.
For the next step, we will add the dry ingredients from the first bowl (flour, etc) to the mixing bowl. Do this by adding half of the dry ingredients at a time, stirring between additions.Mix until just blended, do not over-mix.
Bake this bread for 55-60 minutes or until a toothpick comes out clean
