Transform your overripe bananas into a batch of irresistibly moist and flavorful Chocolate Chip Banana Walnut Muffins using cake mix! This simple, time-saving recipe combines the convenience of a boxed yellow or white cake mix with classic ingredients like mashed bananas, semi-sweet chocolate chips, and crunchy walnuts for a bakery-style treat packed with comforting flavors and textures. Requiring just 15 minutes of prep time, these muffins are perfect for busy mornings, midday snacks, or dessert. With their soft, fluffy crumb and a hint of optional vanilla, each bite strikes the perfect balance between sweet chocolate, nutty crunch, and natural banana goodness. Whether served warm alongside a cup of coffee or enjoyed on-the-go, these muffins will quickly become a family favorite.
Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners or grease them lightly with cooking spray.
In a large mixing bowl, mash the ripe bananas with a fork until smooth.
Add the cake mix, eggs, vegetable oil, milk, and vanilla extract (if using) to the mashed bananas. Stir until the batter is smooth and well combined.
Fold in the chocolate chips and chopped walnuts gently using a spatula.
Evenly divide the batter among the prepared muffin cups, filling each about 2/3 to 3/4 full.
Bake in the preheated oven for 18–22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Remove the muffins from the oven and let them cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely.
Serve warm or at room temperature. Enjoy!
