In a large cast iron pan, melt butter over medium heat. Add the apples, brown sugar, cinnamon, nutmeg, allspice and salt. Cook until apples and slightly caramelized and soft about 5 to 6 minutes.
In a small bowl, whisk together the lemon juice and cornstarch. Add the mixture to the apples then remove from heat.
In a medium bowl, combine the flour, 2 tablespoons granulated sugar, baking powder, salt and 1 teaspoon cinnamon. In another small bowl, stir together the heavy cream, vanilla and melted butter. Stir in the dry ingredients until just combined.
In another small bowl, mix together the remaining sugar and cinnamon.
Spread the dough evenly on top of the apple using a spatula. Sprinkle the sugar cinnamon mixture over the dough.
Bake for 20 to 22 minutes until bubbly. Serve with vanilla ice cream.
