It is with a heavy heart that I reveal here after much serious thought my special chocolate-banana muffin recipe. I have made this hundreds of times, it is my kids' absolute favourite and the one I make at their birthday parties. To me it is muffin perfection, not overly sweet or rich but with a pronounced banana flavour and intense chocolate flavour. I got the original recipe off the internet years ago but have tweaked it so many times that it no longer resembles it in any way. Make sure you have very ripe bananas for this or you will lose half the magic!
