Preheat oven to 350°F (175°C). Grease and flour three 9-inch cake pans.

In a large bowl, combine flour, sugar, salt, soda, and cinnamon.

In a separate bowl, beat eggs and oil together.

Add the egg mixture to the dry ingredients.

Stir until just combined. Do not overmix.

Add crushed pineapple, chopped bananas, and chopped nuts to the batter.

Mix until evenly distributed.

Pour batter evenly into the prepared cake pans.

Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Let the cakes cool in the pans for 5 minutes before inverting them onto a wire rack to cool completely.

Frost with cream cheese frosting (not included in recipe).
