In a large bowl, lightly mix all ingredients until just combined.
Overmixing will make the pancakes tough.
Leave mixture on the counter to rest for 3-5 minutes and then fold it onto itself two or three times, lightly to make sure that the batter is fairly well incorporated.
Cook on a greased skillet or griddle over medium to medium high heat until golden.
If there are large lumps, carefully break them apart with the spatula while the pancakes are cooking.
