Preheat oven to 375 degrees. Grease a 9-inch oven proof skillet.

Mix the melted butter, granulated sugar, vanilla bean paste, and egg together. Sprinkle in the flour, salt, baking soda, cardamom, and ground nutmeg. Mix until incorporated. Fold in the cinnamon just until that batter starts to ribbon with cinnamon.

Pour batter into skillet and spread until it meets the edges. Sprinkle the 2 tablespoons of sugar evenly onto the top of cookie before sprinkling on the 2 tablespoons of dusting sugar.

Bake in the oven for 18-20 minutes. Let cool for at least 30 minutes before serving. Cut into wedges.
