Single Serving Fluffy Pancakes

In a bowl, mix together the all-purpose flour, baking powder, sugar, and salt until well combined.

In a separate bowl, whisk together the milk, egg, and vanilla extract until smooth.

Pour the wet ingredients into the dry ingredients and stir gently until just combined. Do not overmix; it's okay if there are a few lumps.

Heat a non-stick skillet or griddle over medium heat and add the butter. Once melted and bubbling, pour about 1/4 cup of pancake batter onto the skillet.

Cook until bubbles form on the surface and the edges look set, about 2-3 minutes. Flip the pancake and cook for another 1-2 minutes until golden brown.

Repeat with the remaining batter, adding more butter to the skillet as needed.
