Preheat your oven to 350°F (175°C).
Arrange the sliced bananas in a single layer in a baking dish.
In a bowl, whisk together the coconut milk, orange juice, brown sugar, melted butter, ground cinnamon, ground nutmeg, and vanilla extract.
Pour the sauce mixture evenly over the sliced bananas.
Sprinkle the shredded coconut and chopped peanuts (if using) over the top.
Bake in the preheated oven for about 20-25 minutes, or until the bananas are tender and the topping is golden brown.
Enjoy your meal!
