Ingredients

• 3 medium ripe bananas
• 2 large eggs
• 1 cup plain Greek yogurt
• 1 1/2 cups whole-wheat flour
• 1/2 cup vanilla or unflavored protein powder (optional)
• 1/4 cup honey or maple syrup
• 1 teaspoon vanilla extract
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 2 tablespoons olive oil or melted coconut oil
• 1/3 cup chopped walnuts (optional)
• 1/4 cup dark chocolate chips (optional)

Note: If you use protein powder, the batter may become thicker and the bread may bake differently. For a more reliable texture, you can omit the protein powder and use an additional 1/2 cup flour instead.

Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9 x 5-inch loaf pan or line it with baking paper.

Preparing the pan first makes it easier to transfer the batter and remove the bread after baking. Set the pan aside while you prepare the ingredients.

Step 2: Mash the Bananas

Peel the ripe bananas and place them in a large mixing bowl. Mash them with a fork until mostly smooth.

Bananas with plenty of brown spots are ideal because they are naturally sweeter and easier to mash. They also contribute moisture, helping the finished bread stay soft.

A few small banana lumps are perfectly fine and can add little pockets of banana flavor throughout the loaf.

Step 3: Add the Wet Ingredients

Add the eggs, Greek yogurt, honey or maple syrup, vanilla extract, and olive oil to the mashed bananas.

Whisk everything together until the mixture is smooth and well combined.

Greek yogurt provides a creamy texture and contributes protein. It also adds moisture, which is especially helpful when using whole-wheat flour.

For the best results, use plain, unsweetened Greek yogurt. You can use full-fat or low-fat yogurt depending on your preference.

Step 4: Combine the Dry Ingredients

In a separate bowl, combine the whole-wheat flour, protein powder if using, baking soda, baking powder, cinnamon, and salt.

Stir well to distribute the raising agents and spices evenly.

If you prefer a milder banana flavor, you can reduce the cinnamon slightly. For a warmer flavor, add a small pinch of nutmeg.

Step 5: Mix the Batter

Gradually add the dry ingredients to the wet mixture. Fold gently with a spatula until no large pockets of dry flour remain.

Avoid overmixing. Stirring too much can make the bread dense, particularly when using whole-wheat flour.

The batter should be thick but spoonable. If you have included protein powder and the batter seems unusually stiff, add one or two tablespoons of milk until it reaches the right consistency.

Fold in the chopped walnuts or chocolate chips if desired.

Step 6: Transfer to the Loaf Pan

Pour the batter into the prepared loaf pan and spread it evenly.

If you like, slice an additional banana lengthwise and place it on top for decoration. You can also sprinkle a few chopped walnuts over the surface.

Keep in mind that extra toppings may add calories and natural sugars, depending on what you choose.

Step 7: Bake the Banana Bread

Place the loaf pan in the preheated oven and bake for approximately 45–55 minutes.

Start checking around the 40-minute mark, especially if your oven runs hot. Insert a toothpick into the center. It should come out clean or with a few moist crumbs, but without wet batter.

If the top becomes too dark before the center is cooked, loosely cover it with foil and continue baking.

Protein powder can change the texture and baking time, so check the center carefully rather than relying only on the clock.

Step 8: Cool Before Slicing

Remove the bread from the oven and allow it to rest in the pan for 10–15 minutes.

Carefully transfer it to a wire rack and let it cool further before slicing.

This step helps the loaf finish setting and prevents the slices from crumbling. Cutting it while very hot can also make the center seem gummy.

Once cooled, slice into approximately 10 pieces and serve.

Tips for the Best High-Protein Banana Bread

• Use ripe bananas: They provide natural sweetness and moisture.
• Choose thick Greek yogurt: A thick yogurt helps create a tender loaf without making the batter too watery.
• Measure flour accurately: Too much flour can make banana bread dry and heavy.
• Avoid overmixing: Gently fold the ingredients together for a softer texture.
• Check the center: Protein powder can affect baking time, so test the loaf before removing it from the oven.
• Let it cool: Cooling improves the texture and makes slicing easier.

Easy Recipe Variations

1. Chocolate Banana Bread

Add dark chocolate chips or one tablespoon of unsweetened cocoa powder. This variation is perfect for anyone who enjoys a richer dessert-style loaf.

2. Peanut Butter Banana Bread

Swirl two tablespoons of peanut butter into the batter before baking. The nutty flavor pairs beautifully with banana and Greek yogurt.

3. Blueberry Banana Bread

Fold in 1/2 cup fresh or frozen blueberries. If using frozen berries, add them directly from the freezer and fold gently to avoid turning the batter purple.

4. Cinnamon Walnut Banana Bread

Add chopped walnuts and an extra pinch of cinnamon for a comforting, slightly crunchy loaf.

5. No-Protein-Powder Version

Skip the protein powder and use 2 cups of whole-wheat flour in total. The recipe will still contain protein from the eggs and Greek yogurt, although the amount per slice will be lower.

How to Serve

Enjoy a slice for breakfast with coffee or tea. For an extra-protein meal, serve it with additional Greek yogurt or cottage cheese.

You can also toast a slice lightly and spread it with peanut butter or almond butter. Fresh berries make a refreshing side.

Remember that adding toppings changes the nutritional content, so adjust portions to suit your needs.

Storage Instructions

Store cooled banana bread in an airtight container in the refrigerator for up to 4–5 days because it contains yogurt and moisture-rich ingredients.

For longer storage, slice the loaf and freeze individual portions for up to 2–3 months for the best quality. Separate slices with baking paper so they do not stick together.

To serve, thaw a slice in the refrigerator or microwave it briefly until warmed through. You can also toast thawed slices for lightly crisp edges.

Frequently Asked Questions

Is this banana bread high in protein?

It contains protein from Greek yogurt and eggs. Adding protein powder can increase the amount further, but the exact protein content depends on your ingredients and serving size.

Can I make it without honey or maple syrup?

Yes. Very ripe bananas provide natural sweetness, so you can reduce or omit the added sweetener if you prefer. The final flavor will be less sweet.

Can I use all-purpose flour?

Yes. All-purpose flour can replace whole-wheat flour in the same quantity, although the texture and fiber content will differ.

Can I use flavored Greek yogurt?

You can, but flavored yogurt often contains added sugar. Plain Greek yogurt gives you better control over the sweetness.

Why is my banana bread gummy in the middle?

It may need more baking time, or the loaf may have been sliced while too hot. Make sure the center is fully cooked and allow the bread to cool before cutting.
