2/3 cup milk, room temp

1/2 cup packed flour

3 large eggs, room temp

6-8 drops vanilla aroma (German) or 1/4 tsp vanilla extract (US)

1/4 tsp salt

4 tbsp unsalted butter

powdered sugar for dusting

Preheat oven to 220°C.

Mix milk, flour, eggs, vanilla aroma and salt in a blender until the batter is smooth.

Melt 3 tbsp of the butter in a 10in cast iron skillet over high heat until bubbling, pour batter into center of the skillet. It will look like you ruined it, that is normal.

Bake skillet in the preheated oven until puffed and golden, 20-25min. Dust with powdered sugar and serve.
