Instructions

1 Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9×13 inch pan. Make the topping by mixing together 1/4 cup brown sugar, 1/4 cup white sugar, chopped walnuts and 1/2 teaspoon cinnamon. Set aside.

2 In large bowl, mix together 1 cup white sugar, 1/2 cup brown sugar, flour, salt, baking soda and cinnamon. Make a well in the center, and pour in the oil, eggs and sour milk. Beat until smooth, then fold in chopped apples.

3 Pour batter into prepared pan. Sprinkle with topping mixture. Bake in the preheated oven for 45 minutes, or until a toothpick inserted into the center of the cake comes out clean.
