Heat oven to 425°F. Place a 12-inch ovenproof skillet with 4 tablespoon butter in oven (you can also use a 10-inch skillet, but bake pancake for 20 to 22 min).
In a blender, combine eggs, flour, salt and milk until a thin batter forms, about 30 sec.
Remove pan with butter from oven and pour in batter. Return to oven and bake until pancake is puffy, golden and set, 18 to 20 min.
Serve from skillet or transfer pancake to a plate. Drizzle with more melted butter, if desired, and lemon juice; dust with sugar. Serve immediately with fruit.
Notes
Easy to assemble, fun to watch it bake, delicious to eat!
