Ingredients

• 1.5 cups packed light brown sugar
• 0.75 cups all-purpose flour
• 2 teaspoons ground cinnamon
• 0.5 cups butter , chilled and diced
• 1 cup chopped walnuts

Instructions

1. 1 Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9- or 10-inch Bundt pan.
2. 2 Make streusel: Combine brown sugar, flour, and cinnamon in a medium bowl. Cut in cold butter with a fork until crumbly. Stir in walnuts and set aside.
3. 3 Make cake: Stir together flour, baking powder, and baking soda in a medium bowl. Set aside.
4. 4 Cream together sugar and butter in a large bowl until light and fluffy. Beat in eggs one at a time, mixing well after each addition. Stir in yogurt and vanilla. Stir in flour mixture just until blended.
5. 5 Pour 3 cups batter into the prepared Bundt pan. Sprinkle with 1/4 of the streusel, then layer with apples. Sprinkle with 1/2 of the remaining streusel. Pour in remaining batter and top with remaining streusel. Lightly pat down top layer of streusel into batter.
6. 6 Bake in the preheated oven until a toothpick inserted into the center comes out clean, 50 to 60 minutes. Cool in the pan on a wire rack for 15 minutes. Place a cookie sheet over the pan and carefully invert both. Remove the pan; let cake cool completely.
