Preheat your oven to 425°F (220°C) and place a 9x13-inch metal baking dish inside to warm it up. Add 2 tablespoons of butter to the dish and let it melt completely.

In a blender, combine 4 large eggs, 1 cup of milk, 1 cup of all-purpose flour, a pinch of salt, and 1 teaspoon of vanilla extract. Blend until smooth and frothy, about 30-40 seconds.

Once the butter has melted in the baking dish, carefully remove it from the oven. Pour the blended batter over the melted butter evenly.

Return the baking dish to the oven and bake for 22-27 minutes until golden brown around the edges. Avoid opening the oven door while baking.

Once baked, remove from oven and let cool slightly. Serve warm with powdered sugar and syrup, and add fresh fruit or whipped cream if desired.
