Preheat the oven at 350 degrees Fahrenheit (180 degrees Celsius)
Mix flour, spices, sugar, baking soda in a bowl.
Mix all wet ingredients in a larger bowl (except pumpkin and raisins).
Add the dry ingredients to wet ingredients mix with a spoon.
Add the raisins and blend. Add pumpkin and blend.
Spread the mixture with a large spoon or spatula in a 9 inch round pan that you have brushed with a bit of olive oil. I use springform pans.
Bake for about an hour. Check with a toothpick, it should be clean.
Let it cool. The cake will be moist and may seem a bit "wet" on the bottom. This is normal, it will dry once it cools off.
