3 medium sweet-tart apples (such as Granny Smith or Honeycrisp), peeled, cored, and chopped
Instructions
Preheat oven to 350° with a rack in the middle position; lightly coat an 8” round cake pan with cooking spray.
In a medium bowl, whisk together flour, baking powder, and salt.
In a large bowl, whisk eggs until foamy.
Add melted butter, 3/4 cup sugar, rum, and vanilla and whisk to combine.
Add dry ingredients and stir with a wooden spoon or rubber spatula until evenly incorporated.
Fold in apples, and transfer batter to prepared pan. Sprinkle top with remaining 1 tablespoon sugar.
Bake until golden and a toothpick inserted in the middle comes out clean, about 55 minutes. Let cool 15 minutes before inverting onto a cooling rack to cool completely.
