Sweet Potato Pound Cake

I don't know where this sweet potato pound cake recipe came from, only that I added it to my cake folder in February 2012.  Bob likes anything with sweet potatoes, for that matter he may have sent me this recipe.  Bob's birthday was yesterday and this was his birthday cake.

It is so moist and delicious.  I roasted and pureed the sweet potatoes the day before, which made the assembly on baking day a piece of cake (I couldn't help myself.)
