Preheat the oven to 375 degrees
Generously grease 12-cup muffin tin with butter and dust with rice flour, if you don't have rice flour, skip it. The flour does help the batter rise in the pan and getting crispy edges.
In a large, microwave safe bowl combine the coconut milk and butter, heat in the microwave for 1 minute
Add the milk and 2 eggs, whisk until combined. I like whole milk but you can use 2% milk or alternative milk like oat milk.
In a medium sized bowl combine the glutinous rice flour, sugar and baking powder
Add the dry ingredients to the wet ingredients and whisk until smooth
Pour the batter evenly into the 12 muffin cups
Sprinkle with coconut and bake for 45 minutes, or until golden brown
Remove and cool. Muffins will keep for a couple of days on the counter. Pop them in a toaster oven to re-crisp edges. They also freeze pretty well.
