Preheat oven to 350°F. Spray a large tube pan or a 10” x 10” square baking pan with nonstick cooking spray and lightly coat with flour. Blend the margarine, applesauce, 1/2 cup sugar, and 1/2 cup Splenda together. Add the eggs, sour cream, and vanilla, beating until well combined. Add the all-purpose and whole wheat flours, baking powder, baking soda, and salt, mixing until incorporated. In a separate bowl, combine 1/4 cup sugar, 1/4 cup Splenda, cinnamon, and nuts; set aside. Pour half of the batter into the prepared pan. Sprinkle three-quarters of the sugar–nut mixture over the batter. Top with the remaining batter and sprinkle with the rest of the sugar–nut mixture. Bake for 50–60 minutes, until a cake tester inserted into the center of the pan comes out clean. Let the coffee cake cool for 10 minutes. If you baked the cake in a tube pan, invert and remove from the pan.
