Preheat oven to 350°F
Cake
In a large mixing bowl: Whisk together the flour, sugar, salt, baking soda, and cinnamon.
Next add the eggs and vegetable oil to the flour mixture and stir until incorporated.
Lastly, stir in the vanilla, pineapple, bananas and chopped pecans.
Divide the batter evenly into 3 nine inch prepared cake pans.
Bake 25-30 minutes or until set when a wooden toothpick inserted comes out clean.
Cool the cakes in the pans for 10 minutes and then remove to wire cooling racks.
Cool upside down to flatten the tops of the cakes for one hour.
Frosting
Beat cream cheese and butter with a mixer on medium low until smooth.
Gradually add the powder sugar on low blending after each addition until all has been incorporated. Increase speed to medium high and mix until fluffy.
Frost between layers when assembling the cake and cover the top and sides with remaining frosting. Garnish with pecan halves and chopped pecans, if desired.
