Preheat your oven to 180C / 160C Fan / Gas4 / 350F
Line and grease a 2llb loaf tin. Or use a loaf liner
In a mixing bowl cream your softened butter and caster sugar until light & fluffy. You can use a stand mixer here too
Add your eggs, self-raising flour, baking powder, lime zest (from 2 of your limes) and desiccated coconut and beat until combined
Next add 2 tablespoons lime juice to thin the mix a little
Spoon your batter into your loaf tin and bake for 45 - 50 minutes in the centre of your preheated oven. Check after 45 minutes. The cake should be firm to touch and golden brown. You can use a skewer to check if it's baked and it will come out clean if it's ready!
Remove from the oven & leave your loaf cake to cool in the tin. Once totally cold, remove from the tin.
In a small mixing bowl mix your icing sugar with 1 tablespoon lime juice and mix - add a further 1 tablespoon of lime juice if needed. Go slowly as you want a think icing - not one that's going to run everywhere. Mix until really smooth
In another small bowl mix 25g desiccated coconut with the zest of your remaining lime
Spoon your icing down the centre of the cold loaf cake. Use a spoon to spread to the edges
Finally sprinkle your desiccated coconut and lime zest down the centre of the cake
Serve - it's delicious!!
