Pancakes: Whole Wheat Pumpkin Pancakes

I don't cook. I only make pancakes and ice cream, which I guess is cooking in some form or other. Anyway, a couple weeks ago I made whole wheat pumpkin pancakes from a recipe my wife found online (http://pinchmysalt.com/2007/10/14/my-recipe-for-whole-wheat-pumpkin-pancakes/). They were awesome. I had some difficulty with them though because they were so thick. I had to add more buttermilk to the recipe at the end, which ended up almost doubling the amount of buttermilk involved. But, the thickness made them fluffier and because they were whole wheat they were more filling.
