Hi. Theres a whole bunch of recipes here
http://wholesomebabyfood.momtastic.com/teethingbiscuits.htmalthough I haven't tried these myself. I would say though that any recipes that have sugar or salt I would totally omit, they aren't good for a LO and aren't needed. Some of these recipes are suitable for your needs, some have milk or butter, milk you can replace with LO's regular milk whatever that is so it would be safe, butter you can replace with oil but use slightly less than the amount stated (I assume the milk allergy means no butter).
There's also some oaty biscuits here (see reply 16, 18, 20)
http://babywhispererforums.com/index.php?topic=62087.15You'll see the original link posted at reply 16 has milk and butter, but if you read on the butter is replace with oil and in my own recipe experiments there is no milk or butter.
None of these might be exactly what you're looking for, but they are all good finger foods for 6 months+. If you are not sure about how LO will handle dried fruit just yet either totally whizz it into a puree in the oat mix or leave it out. The bananas add enough sweetness anyway.
