A clean, deep caramel-brown crust with a tender, moist crumb underneath, that’s what this banana bread with cake mix delivers every time. The boxed mix already has leavening and stabilizers balanced, so you skip measuring flour and baking soda, and the extra sugar in the mix caramelizes the crust. Ripe bananas bring sweetness and moisture, and the batter is forgiving: add another banana if it looks stiff.
The result is a consistently tender loaf with a crisp edge, no guesswork required.
People always think a single big pan saves time, but then they end up with a gummy, sunken middle that’s raw even after an hour.
Cake mix as the base
Cake mix already has leavening and stabilizers balanced, so you skip measuring flour, baking soda, and salt. The mix’s sugar content helps caramelize the crust and keep the bread moist. Yellow cake mix adds a vanilla flavor that complements bananas.
For banana bread with cake mix recipes, this shortcut delivers a consistent crumb every time, no guesswork.
Why banana ripeness matters
Ripe bananas with brown spots are sweeter, reducing the need for extra sugar. They mash easily and add moisture, critical because cake mix can be dry. The recipe suggests using more bananas if the batter seems dry, ensuring proper hydration.
In banana bread recipes, this step makes the difference between a dense loaf and a tender one.
Two small pans for even baking
Smaller pans, 5×3 inches, allow heat to penetrate evenly, preventing a raw center. They reduce baking time to 25 to 35 minutes, compared to a standard loaf pan which would need longer. Using two pans also makes the bread easier to gift or freeze in portions.
For easy banana bread recipes, this is a practical trick.

Ingredient notes for this banana bread
Yellow cake mix: Already has leavening and stabilizers, so you skip measuring flour, baking soda, and salt.
Ripe bananas: Brown spotted bananas are sweeter and mash easily, adding moisture and reducing extra sugar.
Chocolate chips: Optional and used as a topping; sprinkle on before baking for even distribution.
Make the banana cake batter
Mash the bananas
Fork-mash ripe bananas in a big bowl until smooth, with no large lumps. The finer the mash, the more evenly the moisture integrates into the dry mix.
Combine with cake mix and eggs
Stir in the cake mix and eggs until no dry pockets remain. The batter will be thick but scoopable. If it looks stiff, add another banana, it should drop heavily from a spoon.
Fill the pans
Divide batter evenly between two greased 5×3-inch loaf pans. Smooth the tops with a spatula. Drop the pans gently on the counter to settle any air gaps.
Bake until done
Bake at 350°F for 25 to 35 minutes. Test with a toothpick at 25 minutes, if it comes out clean or with a few moist crumbs, it’s done. Overbaking dries the crust, so check early.
Banana Bread with Cake Mix
Ingredients
- 1 box yellow cake mix
- 3 large ripe bananas more if dry
- 2 large eggs
- 1 handful chocolate chips optional
Instructions
Preheat oven and prep pans:
Heat oven to 350°F (175°C). Grease or line 2 small loaf pans (about 5×3 inches).Mash bananas and mix batter:
In a big bowl, fork-mash bananas until smooth. Stir in cake mix and eggs; combine thoroughly.Fill pans and add toppings:
Evenly split batter into the prepared pans. Sprinkle chocolate chips, walnuts, or other toppings on top if desired.Bake until toothpick clean:
Bake for 25-35 minutes, until a toothpick inserted in the center emerges clean.
Storage and Serving
Let the loaves cool completely in the pans on a rack, about 1 hour. Once cool, wrap each tightly in plastic wrap and then foil.
Store at room temperature for up to 3 days. The crust softens over time, so for the crispest edge, eat within the first 24 hours.
To freeze, wrap the same way and place in a freezer bag for up to 3 months. Thaw at room temperature, still wrapped, for about 2 hours.
Reheat slices in a 300°F oven for 5 minutes to revive the crust. Serve plain, or with butter or cream cheese spread.
The bread is best within the first 2 days; after that, the crumb becomes denser and the crust more tender.
What to swap and what to leave alone in banana bread with cake mix
Yellow cake mix: Any flavor boxed cake mix works: white, butter, or even spice cake. Gluten-free cake mix also works well.
Flavor shifts with the mix you pick, spice cake adds cinnamon notes. Gluten-free mixes vary in moisture; add one extra banana if the batter looks stiff.
Ripe bananas (3 large): No substitute for the moisture and sweetness they provide. Don’t swap with applesauce or yogurt, those change the batter too much. Fewer bananas leave the loaf dry.
More bananas (up to 4) add moisture without hurting structure. The ripeness matters: underripe bananas won’t mash smooth and give less sweetness.
Large eggs (2): Swap each egg with 1/4 cup unsweetened applesauce or 1 flax egg (1 Tbs ground flax + 3 Tbs water). Applesauce keeps the loaf moist but adds a slight apple note. Flax eggs make the crumb a bit denser, still good.
Don’t leave eggs out entirely, they bind the batter.
Chocolate chips (optional, as topping): Swap with walnuts, pecans, dried cranberries, or shredded coconut. No amount change, sprinkle a handful. Walnuts add crunch and a savory note.
Dried cranberries give tart bursts. Coconut toasts into chewy bits.
All mix into the batter fine or top as written.
Tips
- If your bananas are not fully spotted, peel and microwave them for 20 seconds to soften and concentrate sweetness.
- For a more pronounced banana flavor, add 1/2 teaspoon banana extract to the batter; it doesn’t affect moisture.
Frequently Asked Questions
Can I make this banana bread ahead of time and freeze it?
Yes, wrap cooled loaves tightly in plastic wrap and foil, then freeze up to 3 months. Thaw wrapped at room temperature for about 2 hours. Revive the crust by reheating slices in a 300°F oven for 5 minutes.
Why did my banana bread sink in the middle?
The most likely cause is underbaking, the center wasn’t set when you pulled it. Bake until a toothpick inserted in the center comes out clean, which at 350°F takes 25 to 35 minutes. Another cause could be too much banana; if the batter seemed very loose, use 3 large ripe bananas next time.
How is this different from traditional banana bread made from scratch?
It uses a boxed yellow cake mix instead of measuring flour, baking soda, and salt separately. The cake mix already has leavening and stabilizers balanced, so the crumb is consistently tender with less effort. The mix also adds extra sugar that caramelizes the crust for a deeper color.
Can I bake this in a single 9×5 loaf pan instead of two small ones?
You can, but the bake time will increase significantly, expect 45 to 55 minutes, and the center may not bake evenly. The recipe uses two 5×3-inch pans to ensure even heat penetration and a shorter bake. If using one large pan, check the center with a toothpick and cover the top with foil if it browns too fast.
