Mix oil, sugars, and vanilla together in a large mixing bowl. Add beaten eggs. Then add in 15 oz. of canned pumpkin pie mix.
In a separate bowl mix all dry ingredients. Then add to pumpkin mixture.
Spray 3 mini loaf pans, or 1 large bread pan with non-stick cooking spray. Add 2 cups of water to a crockpot and turn on high.
Fill each of your mini loaf pans with an equal amount of pumpkin bread batter, or add it all to a standard loaf pan.
Set your standard loaf pan or mini loaf pans into the crockpot. If you are using mini pans they may not all fit. Therefore, cook in multiple batches or use two crockpots.
Once your pans are in the crockpot cover the top of the crockpot with 3 paper towels and put on the lid.
Cook on high for 1 1/2 - 2 hours for mini pans or 3 - 3 1/2 hours for a standard loaf pan.
Once a toothpick comes out clean, the bread is done. Gently take the pans out of the water (be careful not to burn yourself) and let your bread cool. Then place in the fridge for storing.
Notes
Pumpkin pie mix only comes in 30 oz. cans, but only use half a can per single batch of pumpkin bread. Save the other half to make another batch of pumpkin bread, or make a double batch with one 30 oz. can of pumpkin pie mix. You can use pure pumpkin, but the taste and texture tastes better with canned pumpkin pie mix.
