Separate dough into 10 biscuits. Separate each biscuit into 2 layers. In another small bowl, combine 1/4 cup sugar and 1/2 teaspoon cinnamon. Dip one side of each biscuit in melted butter, then in sugar mixture. Arrange biscuits, sugared side up, over hot apple mixture, overlapping to make 2 rows. Sprinkle with 1/4 cup nuts.
