01 - Toss diced apples with lemon juice, sugar, and cinnamon in a medium bowl. Set aside to allow flavors to meld 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 fully incorporated.
04 - Pour the wet ingredients into the 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 apples into the batter, being careful not to overmix.
06 - Heat a large skillet or griddle over medium heat and 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 more minutes. Repeat with remaining batter, greasing the pan as needed between batches.
08 - Whisk powdered sugar, milk, and vanilla in a small bowl until smooth and pourable, adjusting milk consistency as needed.
09 - Drizzle warm pancakes with glaze immediately before serving.
