To prepare a tropical banana cake baked goods recipe, first preheat oven to 350 degrees F (180 degrees C). Grease and flour two 8-inch round cake pans and line with parchment paper. Sift together the flour, baking powder, cinnamon, nutmeg and salt. Add the wet ingredients to the dry ingredients and mix until just combined. Pour the batter into the prepared pan and bake for 35 to 40 minutes or until toothpick inserted in the center comes out clean. Let the cake cool before removing it from the pan.
