It would be better if the sheet had a radius of about 20-inches (diameter of 40-inches). However, getting some metal as a counterpoise is definitely better than no counterpoise at all!
Will a cookie sheet work for a 2 meter ground plane?
Yes but, you'll need to find something else on which to bake cookies.
OTOH, you can use just about anything metallic to create a ground plane... pieces of wire, metal screen, aluminum foil, etc.
