Sweet Potato Poppy Seed Muffins

So Rylan has been begging for Lemon Poppy Seed Muffins for awhile. We have the poppy seeds but not the lemon. He found a recipe for plain poppy seed muffins in my cookbook yesterday and wanted them tonight. I have been wanting to make sweet potato muffins since, well, we have over 75 lbs sitting in our living room. So we mixed the two. Here is my basic recipe...I didn't write it down, and I didn't measure some of the ingredients.

Sweet Potato Poppy Seed Muffins

1/2 cup butter
2/3 (or less) cup sugar
3/4-1 cup mashed sweet potatoes
2 eggs
1/4 cup of milk
1 tsp vanilla
2 cups flour
2 tsp baking powder
1 tsp baking soda
2 tsp cinnamon
2 T poppy seeds

Cream the butter and sugar together. Add the eggs one at a time. Add the sweet potatoes, vanilla and milk. Mix until combined. Add all the dry ingredients to the bowl and mix until just moistened. Bake at 350 for about 20-25 minutes.

Some notes: We used our white sweet potatoes. They do have a different flavor than the orange. We weren't looking for them taste like pumpkin/squash/sweet potato muffins with lots of cinnamon and nutmeg. We wanted the lighter flavor. I am sure they would taste good to with the above orange fleshed additions and extra spices.
