I would like to make a pumpkin flavored cake using WASC. Do I substitue an ingredient with the pumpkin puree, or, is it in addition to the recipe?

Great website, helpful and yes, addictive.

TIA

I don't know about WASC, but I just checked the Cake Mix Doctor book and she uses:
1 box spice cake mix
1 - 3.4 oz package vanilla instant pudding mix
1 cup pumpkin, canned or fresh mashed
1/2 cup vegetable oil
1/2 cup water
3 large eggs
1 tsp ground cinnamon
1/2 tsp ground ginger

So, it appears that the pumpkin did replace some of the water called for in the mix directions, but I don't know how to figure out how to work that into the WASC recipe

Thank you for the recipe. I'll be using it for Thanksgiving.
