In a large bowl, sift together the flour, baking powder, salt, cinnamon, sugar, and chopped pecans.
Make a well in the middle and pour in the milk, egg, and butter. Mix with a whisk or fork until smooth.
Cook the pancakes:
Heat a non-stick griddle or large pan over medium-high 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. Remove from the pan onto a plate and cook the remaining pancakes.
Serve:
Serve the pancakes warm topped with your favorite toppings and a drizzle of maple syrup.
Notes
To take them over the top, you could toast the chopped pecan pieces in a pan on medium heat until they are golden brown before adding them to the batter or as a topping; an extra step that's not required in the recipe.
Use the right baking powder: Since pancake batter naturally has a mild, neutral flavor, it's important to use aluminum-free baking powder. The metallic flavor will ruin the taste, especially in fluffy pancake recipes that call for 2 or more teaspoons. Trust me on this one.
