How to Make It
Preheat oven to 375°F. Place a 9-inch or 10-inch cast-iron skillet in the oven to heat with the oven. Once preheated, add 1 stick butter to hot skillet and allow to rest in oven until melted.
Meanwhile, combine the remaining Cobbler Batter ingredients in a bowl; set aside.
In a separate bowl, make the Pecan Filling by combining the brown sugar, egg, vanilla, salt, melted butter, bourbon, and pecans. Stir until sugar is partially dissolved.
Carefully remove skillet from oven. Pour batter over melted butter (do not stir—the batter should be separated from the butter). Pour Pecan Filling in center of skillet. Transfer to oven and bake until browned and edges slightly pull away from pan, 30 to 35 minutes. Brush with maple syrup, if desired. Serve warm.
