Step 1

Preheat the oven to 375 degrees F.

Step 2

Combine the sugar and 1 teaspoon cinnamon in a small bowl and set aside. Melt 1 tablespoon butter. Spread the melted butter over the pie crust and sprinkle evenly with the cinnamon sugar. Bake until golden brown, 8 to 10 minutes. Let cool completely, then crumble and set aside.

Step 3

Melt the remaining tablespoon butter in a medium saute pan. Add the apples, vanilla, a pinch of salt and the remaining 1/2 teaspoon cinnamon. Cook, stirring occasionally, until the apples are soft, 12 to 15 minutes. Remove from the heat and allow to cool completely.

Step 4

Build your sundaes starting with the ice cream, dipping the scoop in a mug of hot water if necessary. Top with the sauteed apples, pie crust crumbles, caramel sauce and candied pecans. Serve immediately.
