Combine flour, white sugar, baking powder, cinnamon and salt. In a separate bowl, mix together egg, milk, vegetable oil, vanilla and bananas.: You will notice a dry, sandy texture as the all purpose flour and granulated sugar come together, with the light fragrance of cinnamon mixing into the flour. This dry blend ensures the baking powder is evenly distributed so pancakes rise uniformly. If the mixture feels lumpy from clumps in the flour , whisk them out; a common mistake is leaving large flour pockets that create dense spots in the pancake.
Stir flour mixture into banana mixture; batter will be slightly lumpy.: The wet bowl should smell noticeably sweet from the mashed bananas and fragrant from the vanilla extract . As you whisk the egg and milk the mixture will become glossy, and the oil will create a sheen that helps the batter hold together. Mash the bananas to the texture you like; overmashing removes some pleasant bits, while undermashing leaves chunkier pockets. One pitfall here is underbeating the egg , which can lead to uneven incorporation.
Heat a lightly oiled griddle or frying pan over medium high heat. Pour or scoop the batter onto the griddle, using approximately 1/3 cup for each pancake. Cook until pancakes are golden brown on both sides; serve hot.: As you fold the dry into the wet, you will hear a soft scraping sound and see the batter change from glossy to thicker. The lumps are fine and desirable because overmixing activates the gluten in the flour and makes pancakes tough. Stir just until combined and stop; a common error is vigorous stirring that yields dense pancakes. The batter should pour slowly but hold some shape.
Heat a lightly oiled griddle or frying pan over medium high heat: The pan will give off a faint warmth and you may see a faint shimmer of oil when it is ready. A properly heated surface sizzles lightly when you drop a test batter dot, which creates a golden exterior. Too hot a pan browns the outside before the inside cooks, while too cool a pan yields pale, flat pancakes. Avoid both extremes by aiming for a steady medium high heat and adjusting as needed.
Pour or scoop the batter onto the griddle, using approximately 1/3 cup for each pancake: When the batter hits the pan you will hear a soft sizzle, and the edges will slowly set, making the surface look matte instead of glossy. Using a consistent scoop size helps pancakes finish at the same time, and the surface should show small bubbles forming as it cooks. A frequent mistake is crowding the pan, which reduces heat and causes uneven browning; leave space for flipping.
Cook until pancakes are golden brown on both sides; serve hot: The first side will take about a couple of minutes, during which you will see many small bubbles and edges firming up. When the surface has set and bubbles pop, it is time to flip, revealing a golden brown underside that is slightly crisp. After the second side cooks briefly, the interior should be tender and warm with a fragrant banana aroma. Serving immediately keeps the exterior pleasant and the interior soft; letting them sit too long will cool and lose that fresh texture.
