1/2 cup chopped walnuts
1/2 cup Grape-Nuts cereal
1/2 cup packed light brown sugar
1/2 tablespoon instant coffee powder
3 1/3 cups unsifted cake flour
1 tablespoon baking powder
1 teaspoon baking soda
1 1/2 teaspoons ground cinnamon
1/2 teaspoon salt
1 cup grated peeled apple
3/4 cup nonfat plain yogurt
3 tablespoons canola oil
1 cup plus 1 tablespoon granulated sugar, divided
1/3 cup fruit puree fat replacement
2 large eggs
1 teaspoon vanilla extract
Preheat oven to 350 °F. Coat a 9-inch springform tube pan (10-cup capacity) or coat it with cooking spray.
Stir together walnuts, Grape-Nuts, brown sugar and coffee powder in a small bowl.
Whisk flour, baking powder, baking soda, cinnamon and salt in a mixing bowl. Combine grated apple, yogurt and oil in a small bowl.
Beat 1 cup granulated sugar, fruit puree fat replacement and eggs in another mixing bowl with an electric mixer on medium speed until thickened and pale, 3 to 5 minutes. Blend in vanilla.
Add reserved flour mixture and apple mixture alternately to fruit puree mixture, beating at low speed just until blended, making 3 additions of flour mixture and 2 additions of apple mixture.
Spoon two-thirds of the batter into prepared pan. Spread into an even layer with a rubber spatula. Sprinkle
1 cup of the reserved walnut mixture in a ring on top of the batter in the pan. Cover with remaining batter and smooth top with the spatula. Add remaining 1 tablespoon granulated sugar to remaining walnut mixture
and sprinkle over the top. Bake until the top springs back when lightly touched in the center, 35 to 45 minutes. Cool in the pan for 10 minutes, then turn out onto a wire rack to cool, right-side up.
