01 - Toss diced apples with lemon juice, sugar, and cinnamon in a medium bowl. Set aside to allow flavors to meld.
02 - Whisk together flour, sugar, baking powder, baking soda, salt, cinnamon, and nutmeg in a large bowl until well blended.
03 - In a separate bowl, whisk together milk, eggs, melted butter, and vanilla extract until smooth.
04 - Pour the wet ingredients into the dry ingredients. Mix gently until just combined, being careful not to overmix—a few lumps are acceptable.
05 - Fold the prepared cinnamon apples into the batter gently to distribute evenly.
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, approximately 2-3 minutes. Flip and cook the other side until golden brown, about 2 more minutes. Repeat with remaining batter, greasing the pan as needed.
08 - Whisk powdered sugar, milk, and vanilla in a small bowl until smooth and pourable, adjusting milk consistency as desired.
09 - Drizzle warm pancakes generously with glaze before serving immediately.
