Delightful chewy chocolate cookies that remind me of the 'two-bite brownies' found in every supermarket in Canada and the US. I adapted this from http://www.recipezaar.com/The-Best-Oatmeal-Cookies-Ive-Found-113788 when i craved cookies but had no eggs. Surprise your allergic friends! They store well so can be made well in advance but they tend to disappear quickly. Edit: I have found that some brands of flour in North America take up moisture differently from the Australian flour I used when I developed this recipe. The cookies may flatten completely, in which case decrease the yogurt or increase the flour. The flat cookies are still delicious, and could be used like gingersnaps or cannolis, to be wrapped around something tasty.
