Add the coconut flakes, ¾ cup of chopped pecans, well-drained crushed pineapple, chopped cherries, and sweetened condensed milk to a mixing bowl. Stir to combine completely.
Gently fold in the 1 cup of thawed whipped topping.
Evenly spread the mixture into the premade crust. Cover and chill in the refrigerator for 7 hours. One hour before serving, move the pie to the freezer for sharp slices.
Add ½ cup of the thawed whipped topping to either a disposable piping bag or a quart-size Ziploc bag with a corner snipped off. Pipe dollops in the center and 1 dollop at the edge of each pie slice.
Place the reserved maraschino cherries with stems on top of the whipped topping dollops, sprinkle with toasted coconut flakes, and reserved chopped pecans before serving.
Notes
To make sure that as much liquid is out of the crushed pineapple, I place the drained pineapple on a thick layer of paper towels. Then lay a thick layer on top of the pineapple. Press down to “squeeze” the remaining liquid out. It’s important to remove the excess, or your pie will not set at all.
I also use the paper towel process for the chopped cherries to remove as much of the cherry juice as possible.
Give this no-bake millionaire pie plenty of time to chill in the fridge, so the filling has time to set before serving.
