Sweet Potato Muffins

I tried this sweet potato recipe the other day,

http://www.cookforyourlife.org/recipes/sweet-potato-muffins

substituting 1  1/4 cups whole wheat flour and 1  1/4 cups all-purpose flour for the 2  1/2 cups whole wheat pastry flour that was originally called for.

2 raw sweet potatoes makes this a dense muffin.

But surprisingly not heavy.

I made 22 medium sized muffins that can be frozen and taken out of the freezer when you need a little something packed with a lot of something.
