Directions

Step 1 -Preheat the oven to 350 degrees F.

Step 2 -Spray all the surfaces of a 16-cup nonstick angel food cake pan with nonstick cooking spray.

Step 3 -Flour the inside of the pan.

Step 4 -Add 1/2 cup of the walnuts to a food processor and pulse 3 times.

Step 5 -Add 1/2 cup of the flour, the brown sugar, 1/2 tablespoon of the cinnamon, pulsing a few times to combine.

Step 6 -Sprinkle 4 tablespoons of the cold butter over the top of the mixture and pulse until the walnuts are completely chopped and the mixture resembles small pebbles.

Step 7 -Place the streusel mixture in the fridge while you make the other parts of the cake.

Step 8 -In a medium bowl, whisk the remaining flour, the baking powder, the baking soda, the salt, and the remaining cinnamon.

Step 9 -In the bowl of a stand mixer, beat the remaining butter and 1 1/2 cups of the sugar until fluffy on medium-high speed, about 3 minutes.

Step 10 -Add the eggs one at a time, beating just until the yellow disappears after each egg before adding the next one.

Step 11 -Mix in 1 tablespoon of the vanilla extract and the bananas until just combined.

Step 12 -Gradually add the flour mixture to the banana mixture in thirds alternating with the sour cream between each third, beating until just combined.

Step 13 -Measure out 1/4 cup of the batter, setting it aside for the cream cheese filling.

Step 14 -Stir in the chocolate chips and the remaining walnuts into the remaining batter until just combined.

Step 15 -Measure out 1 cup of the batter to top the cream cheese layer, spooning the rest of the batter into the prepared pan.

Step 16 -In a mixing bowl, add the cream cheese, 1/4 cup of the reserved batter, 1/4 cup of the sugar, and 1 teaspoon of the vanilla extract.

Step 17 -Beat the cream cheese mixture on medium-high speed until smooth and creamy, about 1 minute.

Step 18 -Spoon the cream cheese filling over the batter in the pan and gently smooth it out without touching the sides of the pan. Leave at least 1/4-inch of space on all sides.

Step 19 -Spread the reserved 1 cup of the batter evenly over the filling.

Step 20 -Gently tap the pan on the counter a few times to remove any air bubbles.

Step 21 -Sprinkle the top of the batter evenly with the streusel.

Step 22 -Bake until a toothpick inserted into the cake (without going through the cream cheese center) comes out clean, about 55-60 minutes.

Step 23 -Transfer the cake to a wire rack and allow to cool for 1 hour.

Step 24 -Gently transfer the cake from the pan and allow it to cool on the wire rack until room temperature.

Step 25 -Whisk the powdered sugar, the remaining vanilla, and the milk together in a medium bowl.

Step 26 -Drizzle the glaze over the cake.

Step 27 -Sprinkle the mini chocolate chips over the top.

Step 28 -Serve.
