based on Joy the Baker’s buttermilk pancakes.
The batter will be quite thick. If you want it to be pourable, add one or two more tablespoons of milk — otherwise, simply press the batter with your measuring cup right after pouring into the pan to form a circle shape.
Also, you can separate the egg and whisk the egg white to medium peaks for a fluffier pancake (as per this cornmeal pancake recipe). If you do, simply separate the egg and reserve the egg white until just before the step where you let the batter rest. Whip the egg white using an electric beater or a balloon whisk until it reaches medium peaks, then fold into the pancake batter just until partially incorporated and small wisps of egg white remain. Then proceed to cook as normal.
