Instructions

Preheat the oven to 350℉. Grease a 9X9-inch pan with non-stick cooking spray and line it with parchment paper.

In a large bowl using an electric handheld mixer, cream together the butter and sugar on high until fluffy. Add the egg, vanilla, mashed bananas, and sour cream and continue beating on medium until fully combined.

In another bowl, whisk together the flour, baking soda, baking powder, and salt. Add to the wet ingredients and beat on low just until all the flour mixture is incorporated.

Mix together the brown sugar, cinnamon, and chocolate chips to make the filling/topping. Spread half of the batter evenly into the prepared pan and sprinkle half of the filling mixture on top. Then, gently spread the rest of the batter on top, and lastly, sprinkle on the last of the topping.

Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean. Let cool for at least 30 minutes before serving. Enjoy!

Tips & Tricks (5)

Banana Ripeness Perfection 🍌
Use overripe bananas with dark brown spots for maximum sweetness and moisture in your coffee cake, as they'll provide the most intense banana flavor and natural sugars.
Chocolate Chip Distribution Hack 🍫
Toss chocolate chips in a tablespoon of flour before folding into the batter to prevent them from sinking to the bottom during baking, ensuring even chocolate throughout the cake.
Sour Cream Secret Weapon 🥛
Allow sour cream to come to room temperature before mixing to ensure smoother incorporation and a more tender, velvety cake texture with better rise.
Cinnamon Sugar Swirl Technique 🌀
Create a beautiful layered effect by dividing your cinnamon-brown sugar mixture, using half in the middle of the batter and half as a crumbly topping for maximum flavor and visual appeal.
Moisture Preservation Trick 💧
Cover the cake loosely with aluminum foil halfway through baking to prevent over-browning and lock in moisture, ensuring a perfectly tender and soft coffee cake.
