Stir pancake batter with a wire whisk or fork just until the ingredients are moistened. Any remaining lumps in the batter will disappear during cooking.
To test if the griddle is ready for cooking pancakes, sprinkle with a few drops of water; if bubbles jump around, the heat is just right.
To keep pancakes warm, place in a single layer on a cookie sheet. Cover with foil and place in a 200°F oven up to 10 minutes
