  TO MAKE THE CAKE: In a large mixing bowl, combine the cake mix, baking soda
  and eggs. Measure the Coca-Cola, stir briskly until the foaming stops; add
  to the batter.  Blend ingredients just until moistened, then beat at high
  speed of an electric mixer for 3 minutes, scraping the bowl often. In a
  bowl, combine the mashed bananas with the lemon juice;add to the batter.
  Add the chopped nuts to the batter and beat for 1 minute at medium speed.
  Turn the batter into a well greased, lightly floured 9" X 13" X 2" baking
  disk.  Bake in a preheated 350oF oven for about 40 minutes or until the
  cake tests done.  Cool on a rack for 15 minutes, remove cake from pan and
  turn right side up on a rack to finish cooling. TO MAKE SEA FOAM FrostiNG:
  In the top of a double boiler, combine all of the ingredients, except the
  vanilla extract. Beat for 1 minute at high speed with an electric mixer.
  Place over boiling water (the water should not touch the bottom of the top
  half of the double boiler). Beat on high speed for about 7 minutes until
  the frosting forms peaks when the mixer is raised. Remove from boiling
  water (for the smoothest frosting, empty into a large bowl). Add the
  vanilla extract and continue beating on high speed until thick enough to
  spread, about 2 minutes.  Spread on the sides and top of the cold banana
  cake.  From: "International Cooking with Coca-Cola", a give away pamphlet
