Cream-Filled Banana Cupcakes Recipe

In a large bowl, cream shortening and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Combine the flour, salt, baking soda and baking powder; add to the creamed mixture alternately with bananas and buttermilk, beating well after each addition. Fill paper-lined muffin cups two-thirds full. Bake at 350 ° for 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely. Meanwhile, for filling, in a small saucepan, combine flour and milk until smooth. Bring to a boil. Cook and stir for 2 minutes or until thickened. (Mixture will be very thick.) Cool to room temperature. In a small bowl, cream butter and shortening until light and fluffy. Beat in vanilla and cooled milk mixture until smooth. Beat in confectioners' sugar. Using a sharp knife, cut a 1-in. circle 1 in. deep in the top of each cupcake. Carefully remove tops and set aside. Fill with filling; replace tops. Sprinkle with additional confectioners' sugar if desired.
