These are somewhere between a biscuit and a cookie...they're a bit sweet, but definitely have a bready aspect to them. I got the recipe from epicurean.com, where they were recommended to serve with Stovies. I've copied the recipe here just as it is on the site, but added some notes of my own.
1 1/4 cups sugar
2 cups rolled oats
2 cups flour
1 teaspoon baking powder
1 teaspoon salt
1 1/4 cups shortening (I use room-temperature butter or lard. If you do use butter it comes out a little salty, so either use unsalted butter or skip the salt!)
1/2 teaspoon baking soda
1/2 cup boiling water
2 cups bran flakes (I didn't have any, so I left them out...I honestly didn't notice them on the recipe until I had already started mixing ingredients... I'm sure you could do some extra oats, but it also worked fine to just skip this ingredient.)
Add soda to boiling water and let stand until cool. Mix together flour, baking powder, salt, bran flakes, rolled oats and sugar. Cut in shortening; add water and soda. Roll out thin on a floured board. Bake in hot oven until golden brown.
(I just lightly greased a cookie sheet and smooshed the dough around on it until it was pretty thin. It spread a bit as it cooked and ended up filling the pan, but it had not reached all the corners before I put it in. I baked at 400* for about 10ish min...I didn't set a timer, I just left the oven light on and kept an eye on them as I cooked other things...)
