As requested

I got the recipe for the Cranberry Pumpkin Upside Down Cake here. For the pumpkin puree, I used butternut puree I had in the freezer; for the boxed cake mix I turned to my The Natural Nine: Cooking with Whole Grains cookbook for homemade inspiration and came up with:
2 cups whole wheat pastry flour
1/4 cup barley flour
3 1/2 teaspoons baking powder
1 teaspoon salt
1 1/2 cups evaporated cane juice
(plus 1 teaspoon vanilla extract added with the wet ingredients)

My laptop is being uncharacteristically sluggish, so I'll leave it at that for tonight.
