Follow these simple steps to create your incredible Hummingbird Cake:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking soda, salt, and cinnamon.
3. Combine Wet Ingredients: In another bowl, mix the vegetable oil, eggs, mashed bananas, crushed pineapple, and vanilla until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring just until moistened. Do not overmix.
5. Fold in Pecans: Gently fold in the chopped pecans until evenly distributed.
6. Divide Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Bake in the preheated oven for 30-35 minutes. A toothpick inserted into the center should come out clean.
8. Cool: Allow the cakes to cool in the pans for 10 minutes, then remove from the pans and cool completely on wire racks.
9. Prepare Frosting: While the cakes are cooling, prepare the cream cheese frosting. Beat together the softened cream cheese and butter until creamy. Gradually add powdered sugar and vanilla, mixing until smooth.
10. Assemble the Cake: Place one cooled cake layer on a serving platter. Spread a layer of cream cheese frosting on top. Repeat with the second layer, followed by the third.
11. Frost the Sides: Use the remaining frosting to cover the sides of the cake. Garnish with additional chopped pecans if desired.

These straightforward steps will guide you in creating a Moist Hummingbird Cake to impress your family and friends.
