Preheat your oven to 350 degree F. (180 degree C.) and grease and flour three 9-inch round cake pans. Sift together the flour, baking powder, baking soda, salt, and cinnamon. Next, add the sugar, oil, and eggs; mix well.
Next add the carrot, pineapple, pecans, and coconut. Blend thoroughly.
Distribute the batter evenly among the three pans; you can use a ladle for the batter and fill each pan ladle by ladle to ensure even distribution without fussing with a scale.
Bake the cakes for 35-40 minutes. Be careful not to over-bake them! Because of the high amounts of sugar and add-ins, the cake can quickly crisp too much on the edges. Remove the pans from the oven and cool for 15-20 minutes before turning out onto wire racks to cool completely.
When your cakes are cooled, make your cream cheese frosting. In the bowl of an electric mixer, combine the butter, cream cheese and vanilla. Cream on low to medium speed. With the mixer on low, gradually add the confectioner’s sugar, scraping down the bowl as needed. If it looks too thick, add a little splash of milk.
Frost the cake-spread a thin layer between each layer between each layer of cake, saving the lion’s share for covering the rest of cake.
You can garnish the top with more chopped nuts if you like.
