Making Juicy Pineapple Heaven Cake is simple. Follow these easy steps to create a delightful cake:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, baking soda, and salt until well combined.
3. Cream Butter: In another bowl, cream the softened butter until light and fluffy, about 3-4 minutes.
4. Add Wet Ingredients: Add the drained crushed pineapple, eggs, vanilla extract, and buttermilk to the creamed butter. Beat until fully combined.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
6. Divide Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Place in the oven and bake for 35-40 minutes or until a toothpick inserted into the center comes out clean.
8. Cool: Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Then, remove from pans and let them cool completely on wire racks.
9. Make Frosting: In a separate bowl, combine powdered sugar with a bit of water or milk until you achieve a smooth, spreadable consistency.
10. Assemble the Cake: Once cooled, spread frosting between the layers and on the top of the cake. If desired, sprinkle with coconut flakes for added texture.
