The apple keeps this cake particularly moist.
Preheat oven to 325 degrees Fahrenheit
4 cups all-purpose flour
2 cups white sugar
1 cup packed brown sugar
4 teaspoons grated lemon peel
1/2 cup melted salted butter
1/2 cup canola oil
1/4 cup lemon juice
1/2 teaspoon salt
In a large bowl, blend together until crumbly and set aside 2 cups for the topping.
1 cup sour cream
1 cup milk
2 teaspoons baking powder
2 teaspoons baking soda
2 eggs
2 teaspoons vanilla
1 large apple cut into small cubes
1/2 teaspoon cinnamon or cardamom
Blend the remaining ingredients into the first mixture in the large bowl. Pour into greased 9x12 inch pan. Top with the 2 cups of reserved crumbly topping. You could even add in 1/2 cup of chopped nuts (I used almonds in this recipe and it was delicious) to the crumbly mixture. Bake for 50-60 minutes until a toothpick comes out clean near the middle.
