3/4 cup chopped pecans

1 tablesoon milk

Combine the first five ingredients; set aside. Prepare cake mix
according to package directions. Pour half of the batter into a greased 13 x 9
baking pan. Sprinke with half of the graham cracker mixture. Carefully spoon the
remaining batter on top. Sprinkle with the remaining graham cracker mixture.
Bake at 350 for 40-45 minutes or until a toothpick inserted near the center
comes out clean. Cool on a wire rack. Combine confectioners' sugar and milk
drizzle over cake. Yield: 12 - 16 servings.

I have never done this put a friend of mine put sliced apples in between the
layers. She said it was really good.

Hope you enjoy it.
