To make light and fluffy American-style pancakes, use self-rising flour or add baking powder to your all-purpose flour, don't overmix the batter, and cook on a lightly oiled griddle over medium heat.
Achieving fluffy pancakes involves a few key steps. First, the leavening agent is crucial. Self-rising flour already contains baking powder and salt, simplifying the process. If using all-purpose flour, add baking powder (about 1-2 teaspoons per cup of flour) to create air bubbles that make the pancakes rise.
Next, avoid overmixing the batter. Overmixing develops the gluten in the flour, resulting in tough, flat pancakes. Mix the wet and dry ingredients until just combined; a few lumps are perfectly fine.
Finally, heat a lightly oiled griddle or non-stick pan over medium heat. The ideal temperature is when a drop of water sizzles and evaporates quickly. Pour about 1/4 cup of batter onto the hot griddle for each pancake. Cook for 2-3 minutes per side, or until golden brown and bubbles start to form on the surface. Flip only once.
Let the batter rest for 5-10 minutes before cooking. This allows the gluten to relax, resulting in even more tender pancakes.
