Preheat the oven to 200C/400F/Gas 6.
Grease a six-hole muffin tin with butter.
Blend together the butter, coconut, sugar, flour and eggs in a food processor, until smooth.
Transfer the mixture to a bowl and stir through the mango and chilli.
Divide the mixture evenly into the muffin tin holes and place in the oven for 15 minutes, or until a skewer pushed into a muffin comes out clean.
