Cookbook:Banana Roll with Cream Cheese Filling

This banana roll consists of a thin banana cake, topped with cream cheese frosting and rolled into a log shape. It is similar to a jelly roll or a Swiss roll.

Cake

 * Powdered sugar
 * ¾ cup all-purpose flour
 * ½ teaspoon baking powder
 * ½ teaspoon baking soda
 * ¼ teaspoon salt
 * 3 eggs
 * 1 cup white granulated sugar
 * ⅔ cup mashed banana (2 medium bananas)
 * 1 teaspoon vanilla extract

Filling

 * 1 package (8 ounces) cream cheese, softened
 * 1 cup powdered sugar, sifted
 * 6 tablespoons butter, softened
 * ½ teaspoon vanilla extract
 * ½ teaspoon banana extract
 * ¼ cup powdered sugar

Procedure

 * 1) Preheat oven to 375°F (180°C).
 * 2) Grease a 15×10-inch jelly-roll pan; line with parchment paper. Grease and flour paper; set aside.
 * 3) Spread out a clean, thin dish towel on the work surface (make sure the towel is larger than your jelly roll pan); sprinkle liberally with powdered sugar (this can be done using a mesh strainer).
 * 4) In a small bowl, whisk together flour, baking powder, and baking soda.
 * 5) In a large bowl combine eggs and sugar; beat until thickened. Add bananas and vanilla; beat until well mixed.
 * 6) Stir flour mixture into egg mixture.
 * 7) Spread batter evenly into prepared pan, easing it carefully to the corners with a spatula.
 * 8) Bake for 13–15 minutes or until center springs back when lightly touched.
 * 9) Immediately loosen cake from edges of pan; invert cake onto the prepared towel. Remove pan; carefully peel off paper.
 * 10) Roll up cake in towel while hot, starting with 10-inch side. Cool completely on wire rack, at least an hour.
 * 11) When cake is almost completely cooled, make the filling: beat cream cheese, powdered sugar, butter, and both extracts in small mixing bowl until smooth.
 * 12) When cake has cooled completely, unroll and spread with filling, then re-roll cake. Wrap rolled cake in plastic wrap then refrigerate at least 1 hour (but overnight is best).
 * 13) To serve, unwrap cake and place on a platter. Sprinkle with powdered sugar, and then cut into slices.
