Comfort food at its best: Peanut butter chocolate muffins

I love peanut butter and I love chocolate so what better than these chunky muffins!
They are dead easy to make and pretty reasonable too. I left mine in the oven for longer- about 10 minutes longer and I managed to make one extra.
I also used smooth peanut butter and  a mixture of dark, white and milk chocolate for the chunks. I bought value chocolate from Tesco which seemed to work well. The Lidl chocolate is also good.
Happy baking- here's the link.
