Ingredients
  

  • Before you even preheat the oven let’s get your pantry staple ingredients lined up. Everything here is easy to find, and each item plays a role in creating that yellow cake mix banana bread that’s unbelievably soft and moist.

Core Ingredients

  • 1 box about 15.25 oz yellow or vanilla cake mix
  • This is your no-fail box cake mix base so you don’t have to measure flour, sugar, or leavening—perfect for quick, consistent results.
  • 3 large overripe bananas mashed
  • The darker and spottier the better. Overripe bananas for baking add natural sweetness, moisture, and that classic banana bread flavor.
  • 2 large eggs
  • Eggs help bind the batter and give your loaf structure so it slices cleanly but still feels tender.
  • 1/3 cup vegetable oil or melted butter
  • Oil makes the loaf extra moist and soft while butter adds a richer flavor. Use whichever you prefer or have on hand.
  • 1/4 cup milk or sour cream
  • A small splash of dairy keeps the crumb velvety and prevents dry banana bread. Sour cream adds a subtle tang and extra moisture.
  • 1 teaspoon vanilla extract
  • This gives you that cozy vanilla scented banana bread aroma that fills the kitchen while it bakes.
  • 1 teaspoon ground cinnamon optional but recommended
  • A little cinnamon adds warmth and depth especially if you love that classic banana bread vibe.

Optional Mix-Ins

  • These extras are completely flexible—use one a mix, or skip them if you’re craving a simpler loaf.
  • 1/2 –3/4 cup chocolate chips
  • For a dessert-style twist fold in chocolate chips to turn this into a true sweet treat.
  • 1/2 cup chopped walnuts or pecans
  • Add crunchy walnut topping vibes inside the loaf for texture and a nutty finish.
  • 1 –2 tablespoons coarse sugar or cinnamon sugar for topping
  • Sprinkle over the batter before baking for a light crunch and a pretty golden crust.

Prep Essentials

  • 1 standard loaf pan about 9x5 inches
  • This size works best for even baking and a tall impressive loaf.
  • Nonstick cooking spray or parchment paper
  • Grease the pan well or line it with parchment so your cake mix banana bread slides right out without sticking.
  • With these simple ingredients ready to go you’re just a few steps away from a soft, tender loaf that tastes like you spent all afternoon baking—even though it came together in minutes.

Instructions
 

  • Ready to bake? This cake mix banana bread comes together in one bowl with almost no effort. Follow these simple steps and you’ll have a soft, cozy loaf cooling on your counter in no time.

Preheat and Prep

  • Preheat your oven to 350°F (175°C).
  • Grease a 9x5-inch loaf pan with nonstick spray or line it with parchment paper.
  • A well-greased pan helps the loaf release easily and keeps the crust intact.

Mash the Bananas

  • In a large mixing bowl, add your overripe bananas.
  • Use a fork or potato masher to mash the bananas until smooth with just a few small lumps.
  • The smoother the bananas, the more even your one bowl banana bread texture will be.

Mix the Wet Ingredients

  • Add the eggs, oil (or melted butter), milk or sour cream, and vanilla extract to the mashed bananas.
  • Whisk until everything is well combined and looks creamy.
  • This step builds the base for a super moist, tender crumb.

Add the Cake Mix and Cinnamon

  • Sprinkle the cake mix and cinnamon over the wet mixture.
  • Using a spatula, gently fold in the dry mix until you no longer see streaks of powder.
  • Try not to stir aggressively—do not overmix batter, or the loaf can turn dense instead of soft.

Fold in Optional Mix-Ins

  • If you’re using chocolate chips, walnuts, or pecans, add them now.
  • Fold them through the batter just a few times so they’re evenly distributed.
  • This is where you can really customize your step by step banana bread to fit your cravings.

Fill the Pan and Top

  • Pour the batter into your greased loaf pan, smoothing the top with a spatula.
  • For a pretty finish, sprinkle coarse sugar or cinnamon sugar over the surface if you like.

Bake Until Golden and Set

  • Place the pan on the middle rack of your preheated oven.
  • Bake for 45–60 minutes, or until the top is golden and the center is set.
  • To check doneness, insert a toothpick into the center:
  • If it comes out clean or with a few moist crumbs, your loaf is ready.
  • If you see wet batter, bake for another 5–10 minutes and test again.

Cool Before Slicing

  • Remove the pan from the oven and let your cake mix banana bread cool in the pan for about 10–15 minutes.
  • Carefully lift it out and transfer to a cooling rack to cool completely.
  • Letting it cool helps the loaf firm up, so you get neat slices instead of crumbling pieces.
  • Once your banana bread is cool, slice it thick and enjoy—plain, toasted, or with a swipe of butter. With this simple method, you’ll feel confident baking a loaf that tastes like it came from a bakery, not a box.
