Mix the dry ingredients together (flour, baking powder, salt). Add oil and milk. Mix together just until ingredients are combined.
Roll into 2.5" balls.
Place on ungreased cookie sheet. Press down slightly with the palm of your hand or the bottom of a glass so the tops are flat. Place them so the edges are touching.
Bake for 10-15 minutes.
