Set your oven to 425 F and let it heat while you take:
Two cups corn meal, two cups self rising flour, 1 TBS baking powder (if you don't have SR flour, use AP, 2 TBS baking powder, 1 to 2 tsp salt). Mix together. (Set your 12" black iron skillet on the stove, to get screaming hot, meanwhile:) Add two eggs and 2 to 2 1/2 cups buttermilk (if you don't have buttermilk, you can use regular milk, or clabber regular milk with a touch of cider vinegar) to the dry ingredients. Mix well. Add about half a stick of butter (or some bacon grease) to the skillet, move it around to keep from scorching, pour the melted grease into the batter and mix like hell. Pour batter into skillet, should sizzle as it hits. Place in over for about 20 minutes. Remove when golden brown and delicious. Cut yerself two wedges. Cut in half, slather with butter. Take one and put some honey on it too. Use that one for dessert.
ADDED:
At Safeway, a 5# bag of housebrand corn meal is just under $5. WalMart has SR flour at about $2 for 5#. Eggs - call it two bucks a dozen. To me the packaged mixes just aren't worth it. You don't really save any time and unless you can find them at o, such a deal! they cost a lot more than doing it from scratch.
Also, the above is a quick knock together approximation of what I usually do. If I'm making if to please my wife I use a bit more flour and less corn meal, and add a touch of sugar. If I'm making it for myself, the corn meal goes up to 3 cups and the flour down to a cup. I'll sometimes chop up bacon and onions, fry them up some, and add them to the batter. Play with it.
