01 - In a bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt until evenly blended.
02 - In a separate bowl, whisk the whole milk, egg, melted unsalted butter, and vanilla extract until thoroughly combined.
03 - Add the wet mixture to the dry ingredients and stir gently until just incorporated. A few lumps are acceptable; avoid overmixing.
04 - Transfer the batter to a piping bag, squeeze bottle, or use a teaspoon for easy portioning.
05 - Place a large nonstick skillet or griddle over medium heat and lightly grease with additional melted butter.
06 - Pipe or drop small rounds of batter, approximately 1/2 inch in diameter, onto the hot surface, spacing slightly apart.
07 - Cook for 1 to 2 minutes until bubbles appear and edges begin to set, then flip each mini pancake using a spatula or chopstick. Cook for 1 minute more until golden brown.
08 - Continue cooking remaining batter, greasing the pan as necessary to prevent sticking.
09 - Serve warm in a bowl. Pour milk over the mini pancakes for a cereal-like experience or drizzle with maple syrup and garnish with fresh fruit.
