Oil Biscuits don't rise
I've tried making oil biscuits recently and they don't rise much at all if about ~80% probably. The recipe that I use is:
Baking powder 5.60%
I'll mix the ingredients together just to the point of making sure the contents are well mixed and then I just lay the dough out and cut it up. I bake them at 400 in the oven and until golden brown.
They'll start out just about half an inch thick with dough and end up under an inch thick to max.
