01 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt until evenly combined.
02 - In a separate bowl, whisk together the whole milk, large egg, melted unsalted butter, and pure vanilla extract until smooth.
03 - Pour the wet ingredient mixture into the dry ingredients and stir gently until just combined. Avoid overmixing to keep the pancakes light and fluffy.
04 - Heat a non-stick griddle or skillet over medium heat and lightly grease if necessary. Pour approximately 1/4 cup of batter per pancake onto the cooking surface. Cook until bubbles rise across the surface and edges appear set, roughly 2 minutes, then flip and cook for an additional 1 to 2 minutes until golden brown.
05 - Transfer the cooked pancakes to a plate and allow them to cool slightly so they become pliable without cracking. Gently fold each pancake into a taco shell shape.
06 - Arrange an assortment of sweet fillings such as sliced strawberries, blueberries, banana rounds, Greek yogurt, granola, and maple syrup, or savory fillings like scrambled eggs, crumbled bacon, shredded cheddar cheese, and salsa inside each folded pancake. Serve immediately while warm.
