Crust
Preheat oven to 375 degrees F.
Place cookies in a food process and pulse until the cookies are fine crumbs. Add 1/8 cup of the coconut sugar and add 6 Tablespoons of melted butter into the crumbs and pulse until mixed.
Place cookie crumbs into a 9-inch pie plate. Press crumbs onto the pie plate and bake for 10 minutes. Remove and cool crust for 20-30 minutes.
Caramelized Bananas
Melt the remaining 2 Tablespoons of butter in a non-stick pan and add the mashed bananas, vanilla, 1/8 cup coconut sugar and rum. Cook for 10 minutes on medium high heat until the mixture is caramelized. Place bananas in a bowl to cool for 20-30 minutes. Set aside.
Assembly
Add 2/3 cup dulce de leche to the bottom of the cookie crust. Spread evenly. Place the cooled banana mixture on top of the dulce de leche and also spread evenly. The last layer is the thawed cool whip.
Place pie in the fridge to cool or flash cool in the freezer for 30 minutes, which is what we did. Serves 8.
