Creating Hummingbird Cake is a straightforward process. Just follow these steps for a delightful treat:

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, sift together the flour, sugar, baking soda, salt, and cinnamon.
3. Combine Wet Ingredients: In another bowl, whisk together the oil, eggs, and vanilla extract until smooth.
4. Add Fruits: Stir in the crushed pineapple and mashed bananas into the wet mixture.
5. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients. Mix until just combined; do not overmix.
6. Fold in Nuts and Coconut: Gently fold in the chopped pecans and shredded coconut, if using.
7. Divide Batter: Pour the batter evenly into the prepared cake pans.
8. Bake: Place the pans in the preheated oven. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
9. Cool: Remove from the oven and let the cakes cool in the pans for 10 minutes. Then, transfer them to wire racks to cool completely.
10. Prepare Cream Cheese Frosting: In a mixing bowl, beat the softened cream cheese and butter until smooth. Gradually add powdered sugar and vanilla extract, mixing until creamy.
11. Frost the Cake: Once the cakes are completely cool, spread a layer of frosting between each layer and on the top and sides of the cake.
