Preheat your oven to 425°F (220°C).

Place your oven-safe skillet in the oven with the butter to melt.

In a mixing bowl, whisk together the eggs, milk, and vanilla extract.

Add the flour and salt to the wet mixture, whisking until smooth.

Once the butter has melted, carefully remove the skillet from the oven and pour in the batter.

Return the skillet to the oven and bake for about 20 minutes.

Remove the pancake from the oven, let it cool slightly, then slice into wedges.

Dust with powdered sugar and serve with lemon wedges or your favorite toppings.
