Sift dry ingredients:

Sift the flour, baking powder, sugar, and salt together in a large bowl.

Whisk wet mixture:

Create a well in the middle. Pour in the milk, egg, melted butter, and vanilla. Whisk until just blended; avoid overmixing.

Cook spiderweb pattern:

Grease a griddle or frying pan lightly and preheat to medium-high (375°F / 190°C). Transfer the batter to a squeezable condiment bottle. Once hot, cautiously squeeze a spiderweb pattern on the griddle: begin with four crossing lines, then join them with curving lines. Cook until the batter sets, typically less than a minute.

Flip and finish:

Turn over and cook for another 30 seconds. Modify cooking time depending on line thickness.

Serve with syrup:

Accompany with maple syrup for dipping.
