This is my mother-in-law’s recipe, with a few of my adjustments (adding whole wheat flour and replacing 1/2 the butter with yogurt).  I list the chocolate chips as optional, but Jeremy will tell you that chocolate chips are NOT optional in these muffins, they make the muffins.  These are not a dessert muffin, they are a healthy muffin, but the chocolate does add a bit of indulgence should you choose to use it.

-1/2 c butter, softened to room temp
-1 c sugar
-1 c brown sugar
-1/2 c nonfat plain yogurt
-1 egg
-1 tsp vanilla
-1 c pumpkin puree
-1 c whole wheat flour
-1 c all-purpose flour
-1 c rolled oats
-1 tsp baking soda
-2 tsp cinnamon
-(optional) 1 c nuts, chocolate chips, raisins, craisins, or any combination of the above

Cream butter and sugars with an electric mixer.  Add egg, mix to combine.  Add yogurt, vanilla and pumpkin.  Mix to combine.  In a separate bowl, whisk together flours, oats, baking soda, and cinnamon.  Stir dry ingredients into wet ingredients.  Stir in any desired optional ingredients.  Bake at 350 for 20-25 minutes, until a toothpick inserted in the center comes out clean.
