01 - Toss diced apples with lemon juice, sugar, and cinnamon in a medium bowl. Set aside while preparing the batter.
02 - Whisk together flour, sugar, baking powder, baking soda, salt, cinnamon, and nutmeg in a large bowl until well combined.
03 - In a separate bowl, whisk together milk, eggs, melted butter, and vanilla extract until smooth.
04 - Pour wet ingredients into dry ingredients and mix gently 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 until evenly distributed.
06 - Heat a large skillet or griddle over medium heat. Lightly grease with butter or oil.
07 - Drop 1/4 cup portions of batter onto the hot skillet. Cook until bubbles form on the surface and edges appear set, about 2-3 minutes. Flip and cook the other side until golden brown, approximately 2 minutes. Repeat with remaining batter, greasing pan as needed.
08 - Whisk powdered sugar, milk, and vanilla extract in a small bowl until smooth and pourable. Adjust consistency with additional milk if necessary.
09 - Drizzle warm pancakes generously with glaze immediately before serving.
