Streusel:
1 cup light brown sugar
1 cup chopped apples
1 cup sliced almonds, pecans or walnuts
1/4 cup all-purpose flour
1 teaspoon ground cinnamon
3 tablespoons butter, melted

Preheat oven to 350. Grease a 9 or 10-inch tube pan. To prepare streusel, in a medium bowl, combine brown sugar, apples, nuts, flour, and cinnamon. Stir in melted butter.

CAKE:

2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1 stick butter, softened
1/2 cup granulated sugar
3 large eggs
1/2 teaspoon vanilla extract
1/3 cup orange juice

In a medium bowl, combine flour, baking powder, and baking soda; mix well. In a large bowl, using an electric mixer set on medium speed, beat butter and sugar until light and fluffy. Add eggs, one at a time; beat well after each egg. Add vanilla. Set mixer to low; alternately beat flour mixture and orange juice into egg mixture. Spoon half of batter into tube pan. Sprinkle with half of streusel. Spoon the remaining batter over the streusel, spreading to make an even layer. Swirl batter with a knife to create a marbleized effect. Bake for 15 minutes. Remove cake from oven; sprinkle top with remaining streusel. Return cake to the oven; bake until a toothpick inserted in center comes out clean, about 30-35 minutes. Transfer to a wire rack. Cool completely.

GLAZE: Combine 1/2 cup powdered sugar and 2 1/2 teaspoons orange juice. Mix well. Turn cake out onto a serving plate; invert so streusel is on top. Drizzle glaze over cake; serve. Yields 12 servings. Tip: Sprinkle the glaze with cinnamon for a special touch.

HELPFUL HINT: When brown sugar hardens, add an apple wedge to the container and let stand a couple of days.
