Chocolate Chip Sheet Pan Pancakes

0 Preheat your oven to 425°F (220°C). Lightly grease a standard-sized sheet pan or line it with parchment paper for easier cleanup.
1 In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until well combined.
2 In another bowl, whisk the eggs until lightly beaten. Add in the milk, melted butter, and vanilla extract, and whisk until well combined.
3 Pour the wet ingredients into the bowl of dry ingredients. Use a spatula or wooden spoon to gently fold the mixture together until just combined. Do not overmix; a few lumps are fine.
4 Gently fold in the chocolate chips until evenly distributed throughout the batter.
5 Pour the pancake batter onto the prepared sheet pan, spreading it out evenly with a spatula. ( I used 9 x 13 pan) 
6 Place the sheet pan in the preheated oven and bake for 12-15 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
7 Once baked, remove the sheet pan from the oven and let it cool for a few minutes. Then, slice the sheet pan pancakes into squares or rectangles and serve warm with your favorite pancake toppings, such as maple syrup, whipped cream, or fresh berries.
