Preheat the oven: Preheat the oven to 350°F.
Prepare the cake pans: You will need 2 cake pans, each 8 inches in diameter. Cut out 2 parchment paper circles that will fit inside the cake pans. Spray the bottom of the cake pans with cooking spray, this is so the parchment paper sticks to the pans. Place the parchment papers inside and spray more cooking spray over the parchment paper.
Combine dry ingredients: In the bowl of your mixer combine all the dry ingredients together; flour, sugar, salt, baking soda, baking powder and cinnamon.
Finish the cake batter: To the mixer bowl add the beaten eggs, vegetable oil, vanilla extract, vanilla extract, crushed pineapple and mashed bananas. Mix well until combined. Stir in pecans.
Pour batter in pans: Evenly divide the batter between the two prepared pans and transfer to the oven.
Bake: Bake for 25 to 30 minutes or until the cake is cooked. Insert a toothpick in the middle of the cake, if it comes out clean, the cake is done.
Cool the cakes: Place the cake pans on a cooling rack and cool in the pans for 5 minutes, then remove them from the pans and allow the cakes to cool completely on the cooling rack.
