Slow Cooker Pumpkin Cake

Another recipe from Old Fashioned Pumpkin Recipes.  I haven't tried this one yet but it does sound quite interesting.  Maybe this weekend!

1/2 c granulated sugar
1/2 c dark brown sugar
1/2 c cooking oil
2 eggs, beaten
1 c cooked pumpkin
1 1/2 c flour, sifted
1/2 tsp salt
1/2 tsp cinnamon
1 tsp pumpkin pie spice
1 tsp baking soda
1 c chopped nuts
1/2 c raisins or chopped dates

Cream sugars and oil.  Add eggs and pumpkin and mix well.  Sift dry ingredients together and add to pumpkin mixture.  Add nuts and raisins.  Pour batter into well greased and floured 2-lb coffee can.  Place in slow cooker and cover top of can with half dozen paper towels.  Place lid on cooker and bake on high 2 1/2 to 3 1/2 hours.  Resist temptation to take lid off slow cooker to check progress of cake.  This lets out a tremendous amount of heat.  Cake is done when toothpick inserted in center comes out clean.
