Preheat the oven to 350°F. Place 12 liners into muffin pan(s).
In a large bowl, combine the flour, baking powder, baking soda, and salt. Whisk until mixed well. Set aside.
In the bowl of an stand mixer fitted with the paddle attachment, cream the butter and sugar until light and fluffy, about 5 minutes.
With the mixer on low speed, add the eggs 1 at a time, then add the almond, vanilla, and milk. Your batter may separate if the ingredients are not room temperature. If so, scrape down the bowl and continue, it will smooth out during the next step. With the mixer on low speed add the flour mixture to the batter and beat until just mixed.
Add bananas, pineapple, 1 cup coconut and nuts and mix until combined.
Scoop the batter into the prepared muffin pans, filling each cup about 2/3 full. Gently press a pinch of the remaining coconut on the muffin tops, and bake for 25-30 minutes***, until the muffins are lightly browned on top and a cake tester comes out clean.
Check muffins at 15 minutes; if the coconut starts getting too dark, place a sheet of aluminum foil over muffins.
