Time 40m

Number Of Ingredients 10

4 tablespoons unsalted butter
1/3 cup sugar
1/4 teaspoon ground cardamom
3 large eggs, room temperature
1/2 cup unbleached all-purpose flour
1/2 teaspoon kosher salt
2/3 cup whole milk, room temperature
1/2 teaspoon pure vanilla extract
1 Granny Smith apple, cored, peeled, and cut into 1/4-inch wedges
Sour cream, for serving

Steps:

Preheat oven to 450 degrees with a 10-inch cast-iron skillet on center rack. Melt butter in a medium saucepan over medium-high. When it boils, reduce heat to medium; simmer until foamy. Continue cooking, stirring occasionally and scraping bottom of pan, until foam subsides, butter turns golden brown with a nutty aroma, and milk solids separate into brown specks that sink to bottom, 2 to 7 minutes. Remove from heat; immediately transfer to a heatproof bowl.
Stir together sugar and cardamom. In a large bowl, beat eggs on medium-high until pale and frothy, about 2 minutes. Add flour, salt, milk, vanilla, and 1 tablespoon cardamom sugar; beat until smooth, about 1 minute (batter will be thin).
Carefully remove skillet from oven. Add brown butter and apple, stirring a few times to evenly coat. Spread apple into a single layer; pour batter into skillet. Bake until puffed, crisp on top, and golden brown in places, 20 to 25 minutes. Immediately sprinkle with 2 tablespoons cardamom sugar. Cut into wedges and serve, with sour cream and remaining cardamom sugar.
