Stir the dry mixture into the wet until fully combined.
Pour the batter into the pan over the apples. Bake in the preheated oven for 40-45 minutes or until a toothpick inserted near the center of the cake comes out with a few crumbs.
Cool the cake in the pan for 30 minutes on a wire rack, use a knife to loosen up the sides and flip onto a plate.
Let cool for 1 hour before serving.
Store at room temperature for 2 days or in the refrigerator for up to 3 days or freeze.
