To prepare cake: Preheat oven to 350 degrees F. Coat a 12-cup Bundt or tube pan with cooking spray. Dust pan with flour, tilting to coat and tapping out the excess (or use cooking spray with flour).Advertisement
Whisk whole-wheat flour, all-purpose flour, baking soda, salt, cinnamon, allspice, nutmeg and cloves in a medium bowl.
Combine eggs, egg white and 1 1/2 cups brown sugar in a large mixing bowl. Beat with an electric mixer until fluffy, 3 to 5 minutes. Add pumpkin, orange juice, oil and vanilla; beat until smooth.
Add the dry ingredients to the wet ingredients and stir until just combined. Set aside 2 tablespoons walnuts for the glaze and fold the rest into the batter. Scrape the batter into the prepared pan. Bake the cake until a skewer inserted in the center comes out clean, 50 to 60 minutes. Transfer to a wire rack. Let cool in the pan for 10 minutes.
To prepare glaze & finish cake: Combine 3 tablespoons brown sugar, milk and butter in a small saucepan. Bring to a boil over medium heat, stirring frequently. Cook for 1 minute. Remove from heat and stir in the reserved 2 tablespoons walnuts.
Turn the cake out onto the rack; place the rack over a baking sheet. Drizzle the warm glaze over the top and sides of the cake. Transfer to a serving plate; spoon any glaze from the baking sheet over the cake. Let cool completely.
Equipment: 12-cup Bundt or tube pan
Tip: To toast chopped walnuts: Place in a small dry skillet and cook over medium-low heat, stirring constantly, until fragrant and lightly browned, 2 to 4 minutes.
