Preheat your oven to 425°F (220°C).
In a mixing bowl, whisk together the eggs until frothy. Add the whole milk, sugar, sea salt, and nutmeg. Mix until combined. Gradually add the flour, whisking until smooth.
Heat your oven-safe skillet over medium heat. Add the butter and let it melt, swirling to coat the skillet.
Pour the batter into the hot skillet and immediately transfer it to the preheated oven. Bake for 20-25 minutes until golden brown.
Dust with powdered sugar and serve warm with fresh berries on top.
