Chill the can of coconut milk overnight. The next day, make the cakes. Heat oven to 180C/160C fan/gas 4 and line a 12-hole muffin tin with muffin cases. Put the coconut oil and sugar in a large bowl and use an electric whisk to beat together for about 5 mins until light and creamy. Add the eggs, one at a time, beating until fully combined before adding more. Working in three additions, add the flour, alternating with the coconut milk, then add the vanilla extract.
