Bake Time: 50–60 minutes
Cooling Time: 20 minutes
Total Time: About 1 hour 30 minutes
Servings: 10 slices
Course: Breakfast, Snack, Dessert
Cuisine: American
Method: Baking
Difficulty: Easy
Ingredients
- 3 large very ripe bananas, about 1 1/2 cups mashed
- 1 box (15.25 ounces) yellow cake mix
- 2 large eggs
That’s it! You only need three ingredients for the basic recipe.
Instructions
1. Preheat the Oven
Preheat your oven to 350°F.
Grease a 9×5-inch loaf pan with nonstick cooking spray. For easier removal, line the pan with parchment paper, leaving some overhang along the sides.
2. Mash the Bananas
Peel the ripe bananas and place them in a large mixing bowl.
Mash thoroughly with a fork or potato masher until mostly smooth. A few small banana pieces are perfectly fine.
For consistent results, aim for approximately 1 1/2 cups mashed banana.
3. Add the Eggs
Add the eggs to the mashed bananas.
Whisk until the eggs and bananas are thoroughly combined.
4. Add the Cake Mix
Pour the dry yellow cake mix into the banana mixture.
Use a rubber spatula or wooden spoon to gently stir until no large pockets of dry cake mix remain.
Don’t overmix the batter. Stir only until everything is combined.
5. Fill the Loaf Pan
Transfer the batter to the prepared 9×5-inch loaf pan.
Spread the batter evenly and smooth the top with a spatula.
6. Bake
Bake at 350°F for 50–60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Because ovens and loaf pans vary, begin checking around the 50-minute mark.
If the top becomes too brown before the center is fully baked, loosely cover the loaf with aluminum foil and continue baking.
7. Cool
Remove the banana bread from the oven and place the pan on a wire rack.
Let it cool in the pan for approximately 15–20 minutes.
Carefully remove the loaf and transfer it directly to the rack.
For cleaner slices, allow the bread to cool further before cutting.
Tips for the Best 3-Ingredient Banana Bread
Use very ripe bananas. Bananas covered in brown spots provide more sweetness, moisture, and banana flavor.
Measure the mashed banana when possible. Banana sizes vary. About 1 1/2 cups of mashed banana works well for this recipe.
Don’t prepare the cake mix according to the box. Add the dry cake mix directly from the package. Don’t add the oil, water, or other ingredients listed on the box.
Don’t overmix. Stir just until the cake mix disappears into the wet ingredients.
Use a 9×5-inch loaf pan. A different pan size can change the baking time.
Check the center before removing the loaf. The outside may look completely baked while the center still needs additional time.
Let it cool before slicing. Warm banana bread is delicious, but cutting it immediately can cause the soft loaf to fall apart.
What Cake Mix Is Best for 3-Ingredient Banana Bread?
A standard 15.25-ounce box of yellow cake mix gives this banana bread a classic sweet flavor.
You can also experiment with other cake mix flavors. Keep in mind that changing the cake mix will change the flavor and potentially the texture of the finished bread.
Some delicious options include:
- Spice cake mix
- Butter pecan cake mix
- Chocolate cake mix
- White cake mix
Yellow cake mix is the best place to start if you want a simple, classic banana bread flavor.
How Ripe Should Bananas Be?
For baking, the best bananas are usually past the stage when many people would want to eat them fresh.
Look for bananas with lots of brown spots or skins that have become mostly brown.
Very ripe bananas are softer and sweeter, which means they’re easier to mash and provide stronger banana flavor.
Avoid using green or firm underripe bananas for this recipe.
Optional Add-Ins
The basic banana bread requires only three ingredients, but you can customize it with additional ingredients if you don’t mind turning it into a 4-ingredient-or-more recipe.
Try adding:
- 1/2 cup semisweet chocolate chips
- 1/2 cup chopped walnuts
- 1/2 cup chopped pecans
- 1 teaspoon ground cinnamon
- 1/2 cup peanut butter chips
- 1/2 cup shredded coconut
Fold your chosen add-ins into the batter immediately before transferring it to the loaf pan.
Easy Variations
3-Ingredient Chocolate Banana Bread
Use chocolate cake mix instead of yellow cake mix.
The result is a simple chocolate-banana loaf that’s especially good with chocolate chips added.
3-Ingredient Spice Banana Bread
Replace the yellow cake mix with spice cake mix for warm cinnamon and spice flavors.
This variation is particularly good during fall and the holiday season.
Banana Bread Muffins
Use the same batter to make muffins.
Line a standard muffin pan with paper liners and fill each cup about two-thirds full.
Bake at 350°F for approximately 18–22 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Chocolate Chip Banana Bread
Prepare the three-ingredient recipe as directed, then fold in 1/2 cup chocolate chips before baking.
Sprinkle a few additional chocolate chips over the top for a bakery-style appearance.
Walnut Banana Bread
Fold 1/2 cup chopped walnuts into the batter.
Add a few extra walnuts over the top before baking for extra crunch.
What to Serve With Banana Bread
This easy banana bread is delicious by itself, but you can also serve it with:
- Butter
- Peanut butter
- Cream cheese
- Honey
- Fresh berries
- Greek yogurt
- Scrambled eggs
- Hot coffee
- Cold milk
- Hot tea
For breakfast, serve a slice with fresh fruit and yogurt. For dessert, try warming a slice and serving it with vanilla ice cream.
Make-Ahead Instructions
This banana bread can easily be made a day before you plan to serve it.
Allow the loaf to cool completely before wrapping it tightly or transferring it to an airtight container.
The banana flavor is still delicious the next day, making this an easy option for breakfast, brunch, or meal prep.
Storage
Store completely cooled banana bread in an airtight container or wrap it tightly in plastic wrap.
Keep it at room temperature for up to 3 days.
For longer storage, refrigerate the loaf for up to 5 days.
Refrigerated banana bread can become slightly firmer, so allow individual slices to return to room temperature or warm them briefly before serving.
Can You Freeze 3-Ingredient Banana Bread?
Yes. Banana bread freezes very well.
Allow the loaf to cool completely, then wrap it tightly in plastic wrap followed by aluminum foil or place it in a freezer-safe bag.
Freeze for up to 3 months.
Thaw overnight in the refrigerator or for several hours at room temperature.
You can also freeze individual slices. Wrap each slice separately and place them together in a freezer-safe container.
This makes it easy to grab one serving whenever you want it.
How to Reheat
Microwave an individual slice for approximately 10–15 seconds for a warm, soft texture.
You can also warm slices briefly in a toaster oven.
Try adding a little butter to the warm bread before serving.
Frequently Asked Questions
Can banana bread really be made with only three ingredients?
Yes. Cake mix already contains ingredients such as flour, sugar, and leavening, which is why you don’t need to measure them separately. Bananas provide flavor and moisture, while eggs help give the loaf structure.
Do I make the cake mix according to the box first?
No. Use only the dry cake mix straight from the package. Don’t add the water, oil, or other ingredients listed in the cake directions.
Can I use frozen bananas?
Yes. Thaw frozen ripe bananas before using them. If they release a large amount of watery liquid, drain off the excess before mashing and measuring.
Why is my banana bread still wet in the middle?
The loaf may simply need more baking time. If the top is already brown, loosely cover it with foil and continue baking until the center is set.
Can I make this recipe without eggs?
This particular three-ingredient version relies on eggs for structure. Replacing them may require additional ingredients or adjustments and would change the original recipe.
Can I use a different flavor of cake mix?
Yes. Spice, chocolate, white, and butter-style cake mixes can all create delicious variations.
Can I turn this recipe into muffins?
Yes. Divide the batter among lined muffin cups and bake at 350°F for approximately 18–22 minutes, checking for doneness before removing them from the oven.
