01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk together the milk, eggs, melted butter, and vanilla extract.
03 - Pour the wet mixture into the dry ingredients and stir gently until just combined; some lumps are acceptable.
04 - Fold in the chocolate chips carefully, avoiding overmixing to maintain a tender batter.
05 - Heat a non-stick skillet or griddle over medium heat and lightly grease with butter or oil.
06 - Pour 1/4 cup of batter per pancake onto the skillet. Cook until bubbles appear on the surface and edges are set, about 2 to 3 minutes.
07 - Flip each pancake and cook for an additional 1 to 2 minutes until golden brown and cooked through.
08 - Repeat with remaining batter, greasing the skillet as needed. Serve warm with extra chocolate chips and maple syrup if desired.
