Chocolate peanut butter cookies

These are inspired by “turtles”, a popular American candy invented in the 1930s. A chewy mess of caramel, pecans and chocolate, they've lent their famous flavour-profile to a whole host of cookie spin-offs. Peanuts stand in admirably for pecans. Peanut butter in the mix makes them even more rich – but if you want to really go whole hog, add a cup of chopped dark chocolate to the dough as well.
