Banana Sour Cream Muffins

For some reason all my pictures show this one muffin with the curlicue on top!?!  You'd think that's all I made but this recipe actually makes 18 moist medium muffins

1/2 cup butter
3/4 cup white sugar
1/4 cup brown sugar
2 eggs
1 1/2 cups flour
1 tsp baking soda
1/2 tsp salt
1 cup mashed bananas (about 3)
1/2 cup sour cream
1 tsp vanilla

Cream the butter, sugars and eggs together.

Mix the flour, baking soda and salt together and add to the wet ingredients. And finally add the banana, sour cream and vanilla.

Bake at 375 F for 20 - 25 minutes for muffins.
Or if you want to make a banana loaf, 350 F for 50 minutes.

Here's a close-up of that curlicue!
