Step 1: Preheat oven to 375 degrees F. Coat a 10- x 15-inch rimmed baking sheet with cooking spray.
Step 2: In a medium bowl, combine flour, baking powder, and salt; mix well.
Step 3: Place eggs in the stand mixer and beat at high speed for 4 to 5 minutes, or until fluffy. Beat in sugar, bananas, and 1 teaspoon vanilla. Fold flour mixture into banana mixture until well blended, then pour batter onto baking sheet.
Step 4: Bake 12 to 15 minutes, or until a wooden toothpick inserted in center comes out clean. Remove from oven and turn out onto a clean kitchen towel that has been sprinkled liberally with confectioner's sugar.
Step 5: While cake is still hot, roll it up jelly roll-style from the narrow end; remember you're rolling up the towel, too. Cool on a wire rack.
Step 6: When cool, unroll cake and remove the towel.
Step 7: With an electric mixer on medium speed, beat 1 cup confectioner's sugar, cream cheese, butter, and remaining vanilla until creamy. Spread over top of cake, then roll it up again. Chill at least 2 hours, seam side down. When ready to serve, drizzle with chocolate sauce and sprinkle with nuts, then slice.
