01 - In a mixing bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt until evenly blended.
02 - In a separate bowl, whisk whole milk, large egg, melted butter, and vanilla extract until well combined.
03 - Pour the wet ingredients into the bowl with the dry ingredients and stir gently until just combined; do not overmix, a few lumps are acceptable.
04 - Spoon the batter into a piping bag, squeeze bottle, or use a teaspoon for portioning.
05 - Heat a large nonstick skillet or griddle over medium heat and coat lightly with melted butter.
06 - Dispense small dots of batter, about 1/2 inch wide, onto the skillet, spacing them apart to prevent sticking.
07 - Allow pancakes to cook for 1 to 2 minutes until bubbles appear and edges are set, then flip using a spatula or chopstick and cook an additional 1 minute until golden brown.
08 - Continue with any remaining batter, greasing the pan as necessary between batches.
09 - Serve pancakes warm in a bowl; pour over milk for a cereal-style dish or drizzle with maple syrup and add fresh fruit as desired.
