I heart these cookies! I know that is the lamest pun ever, but it's still true so I thought I'd say it anyway. If you can't decide between your favourite treats this Valentine's Day, why should you? Just go with both! This is actually two entirely separate recipes, that can be made entirely separately, eaten separately etc. For the sake of presentation - and because these two flavours go AMAZINGLY well together - I put one heart inside another for the best value two-for-one you'll see this Valentine's Day! Yup, peanut butter and chocolate heart cookies.
