Preheat. Heat 12" cast iron skillet or oven safe skillet in oven set for 425°F.

Mix. In a medium mixing bowl, whisk eggs, milk, flour, vanilla, maple syrup and salt until well combined and there are no clumps.

Brown the butter. Add 2 tbsp. of unsalted butter to hot cast iron skillet. Then, add skillet back to the oven for a minute or so, to melt and brown the butter.

Bake. Pour Dutch Baby batter into cast iron skillet and bake for 15-20 minutes or until golden brown. When time is up, remove Dutch Baby from the oven. It will be puffy but deflate quickly. This is completely normal and kind of fun to watch, too!

Enjoy. Serve with powdered sugar, fresh berries, maple syrup or jam. Any way you enjoy it, it'll be delicious!
