Coco-lime crepes: In the blender bowl, mix the flour with the sugar, salt, eggs, coconut milk, milk, melted butter, lime zest, and rum.
Mix until a homogeneous batter is obtained.
Let the batter rest for 30 minutes.

Cook the crepes in a pan, brushing it with melted butter. If the batter seems too thick to spread, use a wooden spatula instead of adding more milk.
Keep the crepes warm while preparing the chocolate sauce.

Malibu chocolate sauce: Break the chocolate into a bowl and heat the milk until it boils.
Off the heat, add the Malibu to the milk and pour it over the chocolate.
Wait 1 minute before mixing with a whisk until the mixture is smooth.
Drizzle the crepes with the sauce.
