Preheat the oven to 220°C (428°F).
In a bowl, mix together eggs, milk, flour, sugar, and salt until well combined.
Place butter in an oven-safe pan and put it in the oven to melt.
Once the butter is melted, take the pan out and pour in the batter.
Return the pan to the oven and bake for 20 minutes.
After baking, top with powdered sugar, fruit, syrup, or your favorite toppings.
