Pre heat the oven to 150C Fan/170C/350F/Gas Mark 4 and grease and line a 2lb loaf tin
Mix together the butter, caster sugar and the zest of the limes, using an electric mixer or a spoon, until light and fluffy
Add the eggs and milk and whisk in until smooth, using an electric mixer or hand whisk
Gently whisk in the dessicated coconut and the self raising flour, using a hand whisk
Pour the mixture into the loaf tin and bake for an hour, or until a skewer inserted in the centre comes out clean
While the cake is baking, mix together the juice of the limes with the 4 tbsp caster sugar, the sugar will dissolve into the juice while the cake is baking
When the cake is done, poke holes all over it with a thin skewer and pour the drizzle over it, a little at a time until it is all soaked into the cake, using a pastry brush helps with this
Sprinkle the top of the cake with some dessicated coconut, then leave the cake to cool completely
Store leftovers in an airtight container in a cool place and eat within 3 days. You can also freeze this cake if wrapped well for up to 3 months

Notes
Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
I used a baking spread for the cake and unsalted butter for the buttercream.
You will need a 2lb loaf tin for this recipe (you can test the size of your loaf tin by seeing how much water the tin can hold, 2lb will hold about 2 pints/1100ml of water). If you have a 1lb loaf tin, simply halve the ingredient amounts.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50).
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
