Given hectic lifestyles & dealing with your busy family, sometimes you forget about the bananas sitting on the counter. By the end of the week, you might find yourself with four very ripe bananas that no one really wants to eat. Due to their soft mushy texture, the ripe bananas might not be right for placing on your children’s breakfast cereal. However, they are perfect for making banana breads!

You can make a traditional banana bread that usually uses 3 ripe bananas. But then you are left with one extra banana that might go to waste. The solution?? Make a banana bread with 4 bananas.

Therefore, I have created a nice “emergency” 4 banana bread recipe that uses 4 large ripe bananas. It allows you to make a moist banana bread without wasting any of your ripe bananas. FYI – Ripe bananas (soft with many black & brown spots on the yellow exterior) have much more banana flavor than unripe hard yellow bananas.

However, if you have only 4 medium or small ripe bananas, please see the tips section lower down the page. It has a method to make up for the smaller quantity of mashed bananas.

4 Banana Bread Recipe – Walnuts or Chocolate Chips are Optional

Ingredients

• 4 – Bananas (ripe & LARGE sized) – 460 grams – Use exactly 2 cups of mashed bananas for the best results. Bananas vary in size and this can throw off a recipe.

• 2 – Large Eggs
• 1 Cup – Light Brown Sugar (packed) – 215 grams
• 2 Cups – All Purpose Flour – 240 grams
• 1 Teaspoon – Vanilla Extract – 5 milliliters
• 1 Teaspoon – Baking Soda – 5 grams
• 1 Teaspoon – Baking Powder – 4 grams
• 1/2 Teaspoon – Salt – 3 grams
• Optional – 1/2 Teaspoon – Ground Cinnamon – 1.5 grams
• Optional – 1 Cup – Chopped Walnuts – 115 grams

Servings – Roughly 12 slices

Equipment Needed – Measuring cup & spoons, mixing bowl, long wooden spoon, 9 by 5 metal bread pan, oven mitts, silicon spatula, cooling rack and an oven.

4 Large Bananas Should Equal 2 Cups of Mashed Bananas

Instructions

• Preheat oven to 325 degrees F.
• Mash bananas with a fork.
• Lightly beat eggs.
• Stir bananas, vegetable oil, eggs and brown sugar together in a large mixing bowl. Mix until fully blended. FYI – Mixing in the brown sugar now helps to completely blend the sugar (as it dissolves in the liquids) and allows you to spot any hard sugar lumps (that are easy to smash with a fork).
• Mix in remaining ingredients. Stir until the batter is fully mixed.
• Optional – If you want to enhance this 4 banana bread recipe, you can stir in 1 cup of chopped walnuts after you have mixed the batter.
• Pour the finished batter into a nonstick bread pan. Smooth out the top of the batter within the bread pan.
• Bake in the oven for 67-72 minutes at 325 F or until golden brown.
• Take out of oven and let the banana bread cool down in the bread pan for 10 minutes. Do not remove the banana bread from the bread pan during this 10 minute cool down period. Use oven mitts as the bread pan will be very hot coming out of the oven.
• After 10 minutes, remove the banana bread from the bread pan. Place the banana bread on a cooling rack in order to completely cool. This cool down may take 1-2 hours.
• Please read the tips section below for extra information on how to make this recipe successfully & to avoid common banana bread problems. FYI – Given the higher moisture variability of 4 different sized bananas, please make sure to read the tips below on the “toothpick test” & thermometer test as well as the tip regarding the use of an aluminum foil tent (to prevent excess browning if you need to bake longer than expected).

• Click on our “print recipe” link if you want to print out this recipe. It includes all of the recipe’s ingredients and instructions. However, the recipe print function does not include our tips section. Please read the tips section in order to avoid common recipe problems.
• This recipe is part of Bread Dad’s series on easy Banana Bread Recipes such as walnut banana bread, Greek yogurt banana bread and blueberry banana bread.

• Benefits of banana bread with 4 bananas – If you use fully ripe bananas, it will have a little more banana flavor than many 3 banana breads. It will also be a little moister (but this can also be a downside as you need to make sure the banana bread is not underbaked). See tips below about “toothpick test” and thermometer test.
• Use RIPE bananas for the best results!! Perfectly yellow bananas look great but it also means that they are not fully ripe yet.
• Ripe bananas are soft and have many small brown & black spots on the exterior of the yellow banana peel. The natural sweetness of ripe bananas works best when making banana bread recipes.
• If you use unripe green or yellow bananas, your banana bread will come out bland (with little banana flavor). Unripe bananas are hard and have more starch & less sugar than ripe bananas.

• For the most accurate results, the 4 bananas should equal exactly 2 cups of mashed bananas. This will prevent the banana bread from being too dry or too wet. Too much moisture (too wet) can lead to the banana bread being underbaked.
• Try not to add more than 2 cups of mashed bananas or you will have added too much moisture to the banana bread and it might come out undercooked & mushy. If you add more than 2 cups of mashed bananas, you will probably need to bake the banana bread for longer than expected.
• Try not to use a lot less than 2 cups of mashed bananas, your banana bread might come out a little dry.
• Bananas vary in size and this can throw off banana bread recipes (as large bananas contain more moisture than small/medium bananas). FYI – 4 large-sized bananas equal roughly 1 3/4 to 2 1/4 cups of mashed bananas. In contrast, 4 medium-sized bananas equal roughly 1 1/4 to 1 2/3 cups of mashed bananas. Of course, banana sizes can vary greatly… and my version of medium and large-sized bananas may differ from yours!

• If you don’t have the 2 cups of mashed bananas (i.e. because you have only 4 medium sized bananas), you can make up the missing liquid by adding milk to top things off within the measuring cup. For example, if you have only 1 3/4 cups of mashed bananas, you should add 1/4 cup of milk. As long as the combined mashed bananas & milk equals 2 cups. FYI – Some people like to use yogurt or sour cream if they do not have enough bananas to equal two cups. However, only try to replace a small amount of missing bananas (i.e. 1/4-1/3 cup) as the liquid ratios will start to vary a lot and there will be a greater chance of adding too much or too little moisture (and this will cause the banana bread to be under or overbaked).
• If you prefer not to use milk (i.e. due to lactose intolerance), you can use applesauce as an easy alternative for the missing mashed bananas. They have very similar consistencies & moisture levels. Just add the applesauce to the mashed bananas until the total equals 2 cups in your measuring cup.
• Given the moisture variability of 4 different sized bananas (if you don’t use exactly 2 cups of mashed bananas), please make sure to read the tips below on the “toothpick test” & thermometer test as well as the tip regarding the use of an aluminum foil tent (to prevent excess browning of the banana bread top if you need to bake longer than expected). Please use the aluminum foil tent if you need to place the banana bread back in the oven again for longer baking (i.e. it was undercooked when taken out the first time because you used too much mashed bananas).

• Optional – This recipe helps you to create a delicious & moist banana bread. However, if you want to “enhance” this banana bread recipe, you can add 1 cup of chopped walnuts after you have completely mixed all of the other ingredients. Of course, always check for potential nut allergies before serving any banana breads that include tree nuts or peanuts. Do not add the chopped walnuts if anyone who might eat your banana bread has a nut allergy.
• Optional – If you would like to add chocolate chips instead of chopped walnuts, you can use 3/4 cup of MINI chocolate chips. “Normal” sized chocolate chips tend to sink to the bottom of this moist banana bread. Mini-sized chocolate chips tend to spread out better in the batter.
• Optional – If my bananas are not super ripe, I sometimes add a 1/2 teaspoon of ground cinnamon in order to add a little extra flavor. However, if my bananas are fully ripe, I generally find that the banana bread doesn’t need any extra spices.
• Visitors – What additional ingredients (i.e. chopped walnuts) have you added to this recipe to make it more unique or special? Please post your ingredient additions in the comment section below. Your tips & suggestions are a great help to beginning banana bread makers.

• You should use a NEUTRAL flavored vegetable oil (i.e. corn or canola oil) in order to make this four banana bread recipe. Stronger flavored oils (i.e. peanut oil or olive oil) may negatively impact the banana bread taste.
• You can also use unsalted butter instead of vegetable oil if you want to add a slightly buttery taste to your banana bread. Just replace the oil with butter on a 1:1 basis.
• However, I find that vegetable oil creates a slightly moister banana bread because vegetable oil stays liquid at room temperature (whereas butter is a solid at room temperature).
• Alternative to this 4 banana bread recipe – You can make two loaves of our 2 Banana Bread Recipe (2 + 2 = 4).
• Of course, if you have 4 ripe bananas, you can always freeze one banana and make a regular 3 banana bread. However, that one frozen banana will take up space in your freezer and be forgotten forever!

• The brown sugar adds a slightly richer flavor to banana breads (versus the use of white granulated sugar).
• However, you can use a 50/50 mix of brown & white granulated sugar if you want less brown sugar flavor.
• Use FRESH ingredients (i.e. baking soda and flour) for the best results. For example, if you use stale baking soda and/or baking powder, your quick bread will not rise properly and will be too dense. Baking soda & powder is best if used within 6 months of opening the container. Using baking soda from an open container (that has been deodorizing your refrigerator for months) will lead to subpar results. Old & hard baking soda/powder may result in rising problems and/or leave small bitter clumps in your quick bread.
• Store your ingredients (i.e. flour & sugar) in airtight containers to avoid “funky” flavors in your baked goods as well as to prevent contamination by moisture (in the air), dust, pests, etc.
• Do not overmix the batter or your 4 banana bread will come out dense and gummy. I never use an electric mixer when making banana bread. It is too easy to overmix the batter with an electric mixer. Stick with a large spoon when mixing your batter.
• Do NOT use an electric mixer to mix your ingredients (when combining the wet and dry ingredients). Stick to an old fashioned wooden spoon. An electric mixer can overmix the ingredients and the banana bread will turn out rubbery & gummy.

• To prevent your bananas breads from sticking to the bottom of your bread pan (especially if you are using “sticky” ingredients such as chocolate chips or blueberries), you should consider either “greasing” the bottom of the pan with butter or vegetable oil, using a cooking spray, using a nonstick pan or lining the interior of the bread pan with baking parchment paper.
• However, don’t grease the bread pan near the top of the pan. There will be nothing for the batter to cling to as it rises. This could cause the bread top to collapse as it rises.
• Please use the suggested 9 x 5 bread pan to make this banana bread recipe. If you start using different sized pans, there is a greater potential for bread top collapses (potentially less bread pan “wall” support for the quick bread as it rises), different interior batter to exterior bread ratios (thus the need for different baking time lengths), smaller pans are more likely to overflow, etc.
• Use a metal bread pan (and not a glass bread pan) to make this banana bread recipe. Glass pans bake faster than metal and can overbake this banana bread.
• This recipe is based on using a traditional oven (which most people have) and NOT a convection oven. Convection ovens blow air around inside the oven and this bakes things faster than in a traditional oven. Therefore, if you use a convection oven, this recipe is more likely to be overbaked.
• Place your banana bread in the middle of your oven. If you place it on the top or bottom racks, the banana bread may be too near the oven’s heating element and bake faster than expected.

• This doesn’t happen often but if the top of the banana bread looks too moist or undercooked, you should try the “toothpick test”. Gently push a long wooden toothpick or wooden skewer into the top of the bread and see if any batter sticks to the toothpick. If batter is sticking to the toothpick/skewer then it hasn’t completely cooked. Place the bread pan back into the still hot oven for another 3 to 5 minutes. Make sure to wear oven gloves because the bread pan will be very hot. After the 3 to 5 minutes, remove the bread pan and test the quick bread again with a toothpick/skewer.
• Instead of the “toothpick test”, some people like to use a bread thermometer to test if their banana bread is done. Generally, a “quick bread” (i.e. banana bread or pumpkin bread) is done when the internal temperature reaches 200-205 degrees F. Just make sure to measure the temperature in the center of the loaf for the most accurate reading.
• Make sure that your oven has been completely preheated. If the oven has not been properly preheated, this quick bread could come out undercooked. Use an oven thermometer (i.e. one that hangs inside your oven) to check the interior oven temperature before baking.
• Portable oven thermometers are also great for telling if your oven temperature matches what you set on the oven temperature dial. Some ovens (esp. older ovens) can be off by 25+ degrees.

• If your banana breads suffer from over browning, it could be due to your oven running hotter than the dial temp (use a portable oven thermometer to check the internal temperature), using a glass bread pan vs a metal bread pan (glass pans cook faster than metal pans), using a convection oven vs a traditional oven (most recipes are designed for traditional ovens and convection ovens bake the exterior of a banana bread faster than traditional ovens), etc.
• Some people like to prevent over browning of their banana bread tops by placing an aluminum foil “tent” over the bread pan after the banana bread has been baking for roughly 40 minutes. They take a sheet of aluminum foil and bend it in half so it is shaped like a tent/triangle. This shape prevents the foil from touching the top of the batter during the baking process. Always wear oven mitts when placing foil over a hot bread pan.
• Long-term storage – If you want to keep your banana bread for more than 1-2 days (depending on your home’s temperature & humidity), you will need to freeze it. Please read Bread Dad’s How To Freeze Banana Bread for more details.

• If you have a problem with a quick bread recipe, please make sure that you are following the recipe exactly (i.e. using the correct oven temperature), using the correct amounts of ingredients (i.e. don’t eyeball the measurements versus using a measuring cup or accidentally add a tablespoon when a teaspoon is called for), using the correct ingredients (i.e. baking soda/powder versus yeast or all purpose flour versus bread flour), etc. Please don’t “wing” things with recipes.
