Banana Jelly Roll Bars w/ Cream Cheese Frosting

-sorry, no picture on this one, I just got a NEW camera!  Need to figure it out!  But take my word for it - if you like banana flavor, and you like cream cheese, this is great.

Bars:

½ cup butter, softened
2 cups sugar
3 eggs
1-1/2 cups mashed ripe bananas (about 3 medium)
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
Dash salt

Cream Cheese Frosting:
1 package (8 ounces) cream cheese, softened
½ cup butter, softened
4 cups confectioners' sugar
2 teaspoons vanilla extract

In a large mixing bowl, cream butter and sugar until light and fluffy. Beat in the eggs, bananas and vanilla. Combine the flour, baking soda and salt; stir into creamed mixture just until blended. Transfer to a greased 15-in. x 10-in. x 1-in. baking pan. Bake at 350° for 20-25 minutes or until a toothpick inserted near the center comes out clean. Cool in pan on a wire rack.

For frosting, in a small mixing bowl, beat cream cheese and butter until fluffy. Add confectioners' sugar and vanilla; beat until smooth. Frost bars. Yield: 3 dozen.
