01 - In a medium bowl, toss diced apples with lemon juice, sugar, and cinnamon. Set aside to let flavors meld while preparing the batter.
02 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, salt, cinnamon, and nutmeg until thoroughly combined.
03 - In a separate bowl, whisk together milk, eggs, melted butter, and vanilla extract until smooth and well blended.
04 - Pour the wet ingredients into the dry ingredients and mix gently with a spatula or whisk until just combined. Do not overmix; a few small lumps are acceptable for fluffy pancakes.
05 - Gently fold the prepared seasoned apples into the batter, being careful not to overmix.
06 - Heat a large skillet or griddle over medium heat. Lightly grease with butter or oil, adjusting heat as needed to maintain even cooking temperature.
07 - Drop 1/4 cup portions of batter onto the hot skillet. Cook until bubbles form on the surface and edges appear set, approximately 2-3 minutes. Flip carefully and cook the second side until golden brown, about 2 additional minutes. Repeat with remaining batter, greasing pan as needed between batches.
08 - While pancakes cook, whisk powdered sugar, milk, and vanilla in a small bowl until smooth and pourable. Add additional milk 1 teaspoon at a time if needed to reach desired consistency.
09 - Drizzle warm pancakes generously with glaze immediately before serving. For best results, serve hot and fresh from the griddle.
