01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly mixed.
02 - In a separate bowl, whisk the milk, eggs, melted butter, and vanilla extract until smooth and homogenous.
03 - Pour the wet mixture into the dry ingredients and gently stir until just combined, allowing some lumps to remain; avoid overmixing.
04 - Fold in the semi-sweet chocolate chips evenly throughout the batter.
05 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter.
06 - Pour 1/4 cup of batter per pancake onto the skillet. Cook for 2 to 3 minutes until bubbles form and edges appear set.
07 - Flip pancakes and cook an additional 1 to 2 minutes until golden brown and fully cooked through.
08 - Continue with remaining batter, adding butter to the skillet as needed to prevent sticking.
09 - Stack warm pancakes and drizzle generously with maple syrup before serving.
