Mix all ingredients well. Place in refrigerator overnight before using. This will keep well for three days. Batter will be thick.
Just spread it out when you pour it on the griddle. It is also okay to add a little more buttermilk, but leave the batter thicker than normal pancake batter.
You can also make them the morning you plan to use them, and allowThe batter to sit on the counter about 30 minutes before cooking the pancakes.
