1/2 c melted butter
1 1/2 cups granulated sugar
2 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
1 cup whole-wheat flour
1 teaspoon baking soda
1 teaspoon salt
1 teaspoon ground cinnamon
3 medium apples, peeled and cut into chunks
1 cup chopped walnuts
Preheat oven to 350 degrees Fahrenheit.
Stir together butter, sugar, eggs and vanilla.
In a separate bowl, combine flours, baking soda, salt and cinnamon.
Add dry ingredients to wet; stir until combined.
Stir in apples and walnuts. Batter will be thick, more like a cookie dough than a cake batter.
Spoon into a greased 13 x 9 x 2-inch pan.
Bake at 350 degrees for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean.
For glaze, combine 1 cup powdered sugar, 1 teaspoon maple extract and enough maple syrup to make a pourable glaze. Drizzle over partially cooled cake.
