Do you have a microwave? I've never done them in the oven.
For me, I put soup pack into a bowl, add a bit of water at a time until it's a medium paste - a little lick puree. This bit's trial and error to how you like them. I like them a bit thinner, but I started out thicker.
Then, I cut a piece of non-stick baking paper, and blob them on with a teaspoon to make a kind of clock face, one in the middle, one at 12, 3, 6, and 9, and then one in between the 4 outside ones. (Hope this makes sense!!) With the back of the spoon I flatten them a bit, then put them in the micro. I have a 800w one, and it takes about 50 seconds. Then, check them (put them in for longer if necessary), and peel them off the paper and into a bowl.
You wouldn't be able to peel them off the plate. I think the point of the paper is that you can make them really thin and peel them off. When I make mine really thin they do come out like crisps. Obviously not the crisps I know and love, but the same thickness, and I can snap them.
Why not try one of the other recipes? Look at the stickies - i assume the recipes bit is still there. I've made muffins and all sorts.
