Caramel Banana Muffins

Muffin Ingredients
1/4 cup butter
1 cup sugar
1 egg
1 1/2 cups mashed ripe banana
(about 3 large bananas)
1 tsp vanilla
1 1/2 cups flour
1 tsp baking soda
1/2 tsp salt

Caramel Icing
2 Tbsp butter
1/4 cup packed brown sugar
1 Tbsp. milk
1/2 cup powdered sugar

In a small mixing bowl, cream shortening and sugar. Add eggs; beat well. Add bananas and vanilla; mix well. Combine the flour, baking soda and salt; add to creamed mixture. Fill paper-lined muffin cups three-fourths full. Bake at 350 degree for 15-18 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing them from the pan to a wire rack to cool completely. For icing, in a small saucepan, melt butter over medium heat. Stir in brown sugar and milk; bring to a boil. Cool slightly. Whisk in confectioner's sugar. Transfer to a small resealable plastic bag; cut a small hole in a corner of bag and drizzle over muffins. (I like to just spread the warm muffins with the icing and cover the whole top).
