Bake the bake plantains for about 25 minutes. Let them cool and peel.
Mash the plantains and add the eggs, ground cinnamon, coconut milk, ½ cup melted butter and sugar.
Pour into a casserole dish.
In a medium bowl mix all the topping ingredients, until well combined. Sprinkle over the plantain mixture and bake at 350°F for about 40 minutes or until golden brown. Serve.
