Found this on SparkPeople and it is a WW recipe. Haven't tried it yet but will as soon as I get the ingredients.
1 box angel food cake mix
1 15oz pumpkin
2 TBSP pumpkin pie spice
1 cup water
Preheat oven to 350 degrees. Spray a 9x13 pan with Pam.
Mix spice with pumpkin, add water, stir and add cake mix.
Stir vigorously until well mixed.
Pour into prepared pan.
Bake 30 minutes.
Cool and cut into 16 squares
Cool whip may be added to top each square but it has not been figured into the calories or points value.
WW Points = 2
