The ones I make look similar to this. She has the same ingredients in hers, but some ingredients call for different amounts.

1 cup walnuts (optional)
Cinnamon and Sugar mixture: 1/2 cup sugar to 1 1/2 tsp. cinnamon
Melt butter. Beat in sugars, eggs, cinnamon and vanilla. Stir in flour baking powder and salt. Stir in apples and walnuts. Spread into greased 9 x 13 pan. Sprinkle with cinnamon and sugar mixture. Bake at 350 for 35 minutes. Cool and cut into squares.
