This muffin is the combination of 2 flavours that I really love: chocolate and coffee, the flavour that we call Mocha ^^.
This little tart is so tempting, creamy and rich filling with a hint of vanilla ^^, I think most of people love it.
There are a load of banoffee pie recipes, and many of them using dulce de leche, that's not easy to buy in some place.
