In a large bowl, sift together the flour, baking powder, salt, and sugar. Make a well in the middle and pour in the water, egg, butter, and vanilla extract. If using cinnamon or other flavorings, add it now. Break up the egg first with a fork, and then begin to combine the flour, working from the outside of the bowl in, until just combined and mostly smooth.
Cook the pancakes:
Heat a non-stick griddle or large pan over medium heat. Once hot, grease, spray, or melt butter on the hot surface. When using an electric griddle, heat it somewhere between 300 and 350F.
Immediately, pour ¼ cup of pancake batter onto the greased pan. Cook the pancakes for about 2 minutes, until the edges begin to look defined and bubbles form. Flip the pancakes over and cook for another minute on the other side. Avoid pressing down on the pancakes after flipping; this will make them dense and chewy. Remove the pancakes from the pan onto a plate and keep them warm while you cook the rest.
Serve:
Plate a few pancakes on a plate, top with your favorite toppings and syrups.
Refrigerate leftovers for up to 4 days or freeze for up to 3 months. Microwave them for 30 seconds to 1 minute or toast them until warm.
Notes
Add-ins/Mix-ins:
Add up to 1 cup of fruit, cut small, like diced strawberries or blueberries (whole), to the batter by gently folding them in with a spatula.
Chocolate chips: about ½ cup to the batter, folded gently.
Flavor your batter by adding:
1 ½ teaspoons cinnamon or pumpkin pie spice
1 to 2 teaspoons almond or maple extracts
¼ cup of jam or jelly to the batter
Zest of 1 orange or 1 lemon
Consistency Tips: The best visual is always the quick video above.
If your batter is too thick, you likely added too much flour into the cup (or omitted the butter). Add 2 more tablespoons of milk to thin it, then mix gently.
If your batter is too runny (often due to under-measuring), add 1 to 2 tablespoons more flour, mix gently, and wait 5 minutes before cooking.
If your pancakes are flat, your baking powder is no longer active (gone bad). This ingredient cannot be omitted.
Omitting the butter results in a thicker batter (and less flavor). Omitting the vanilla will also yield a more bland batter.
