Method
Step-by-Step
- Heat the oven to 350°F (175°C). Grease a 9-by-13-inch baking pan and line the bottom with parchment.
- Beat the softened cream cheese, sugar, egg yolk, vanilla, and flour until smooth. Set the filling aside.
- Whisk the flour, baking soda, and salt together in a separate bowl.
- Beat the softened butter and sugar until light and creamy. Beat in the eggs one at a time, then mix in the vanilla and mashed banana.
- Add the dry ingredients to the banana mixture and mix just until combined. Fold in the chocolate chips without overmixing.
- Spread approximately half of the banana batter in the prepared pan. Carefully spread the cream cheese mixture over it, leaving a narrow border around the edges, then spoon and gently spread the remaining batter over the filling.
- For the crumb topping, combine the flour, brown sugar, and cinnamon. Cut in the cold butter until coarse crumbs form, then mix in the chocolate chips and sprinkle over the batter.
- Bake for 55–70 minutes, checking around 55 minutes, until the top is set and a toothpick inserted into the banana-bread portion comes out with moist crumbs but no wet batter. If the top browns early, tent the pan loosely with foil.
- Cool in the pan for at least 30 minutes before slicing. For cleaner layers, refrigerate the cooled coffee cake for 1–2 hours before cutting.
Notes
Use very ripe, heavily speckled bananas for the best moisture and flavor. Keep the cream cheese filling as a distinct middle layer instead of swirling it heavily. Store covered in the refrigerator because of the cream cheese filling.
