- 2 large eggs
- 3 tablespoons plain Greek yogurt
- 2 tablespoons oat flour
- ½ teaspoon baking powder
- ¼ teaspoon ground cinnamon (optional)
- ½ teaspoon vanilla extract (optional)
- 1 pinch of salt

- 1 teaspoon chia seeds
Optional Additions

Tip: Very ripe bananas with brown spots provide more natural sweetness, so you may not need any additional sweetener.
👩🍳 Step-by-Step Instructions
Step 1: Prepare the Bananas 🍌
Peel two medium ripe bananas and place them into a large microwave-safe ceramic bowl.
Use a fork to mash the bananas until they become soft and creamy.
A few tiny banana lumps are perfectly fine, but avoid leaving large chunks.
The smoother the mashed bananas, the more evenly the cake will cook.
Pro tip: Choose ripe bananas rather than firm, underripe ones. Ripe bananas mash more easily and give the cake a sweeter, richer flavor.
Step 2: Add the Eggs and Greek Yogurt
Crack two large eggs into the bowl of mashed bananas.
Add three tablespoons of thick plain Greek yogurt.
Using a whisk, mix everything thoroughly until the ingredients are well combined.
The mixture should become smooth, creamy, and slightly frothy.
Greek yogurt helps create a tender texture and adds a subtle tangy flavor that balances the sweetness of the bananas.
Step 3: Add the Dry Ingredients
Sprinkle the following ingredients into the banana mixture:
- 2 tablespoons oat flour
- ½ teaspoon baking powder
- A pinch of salt
- Ground cinnamon, if using
Gently whisk until no dry pockets remain.
The batter should be thick but still easy to stir.
Avoid excessive whisking once the dry ingredients are incorporated.
Important: This recipe produces a soft, moist microwave banana cake rather than a firm, traditional oven-baked loaf.
Step 4: Prepare the Mixed Nuts and Seeds 🌰
In a small bowl, combine:
- Chopped walnuts
- Sliced almonds
- Pumpkin seeds
- Chia seeds
Mix them together.
Set aside approximately one-third of the mixture for the topping.
Fold the remaining nuts and seeds into the banana batter.
This creates delicious little crunchy bites throughout the cake.
Tip: Chop large walnut pieces into smaller bits so they distribute evenly and don’t weigh down the batter.
Step 5: Add the Crunchy Topping
Sprinkle the reserved nuts and seeds evenly over the surface of the banana batter.
Make sure the walnuts, almonds, pumpkin seeds, and chia seeds are spread across the top.
The topping gives the finished banana bread a beautiful homemade appearance.
For an extra aromatic flavor, you can lightly toast the walnuts and almonds in a dry skillet before adding them.
Step 6: Microwave the Banana Bread
Place the microwave-safe bowl inside the microwave.
For a microwave rated at approximately 900–1,000 watts, start with 3 minutes on high.
Carefully check the cake.
If the center is still wet or visibly runny, continue cooking in 20–30-second intervals.
Depending on the microwave, bowl dimensions, and batter thickness, the cake may need approximately 3–5 minutes or longer.
The banana bread is ready when:
- The surface looks set.
- The center no longer contains liquid batter.
- The cake has risen slightly.
- A toothpick inserted near the center comes out without wet batter.
- The center reaches at least 160°F (71°C) because the recipe contains eggs.
Safety note: Use only microwave-safe cookware. A large, relatively shallow bowl cooks more evenly than a narrow, deep bowl. If the cake is very thick, divide the batter between two microwave-safe dishes to avoid an undercooked center.
Step 7: Let the Cake Rest
Once the cake is fully cooked, carefully remove the bowl using oven mitts.
The bowl will be very hot!
Let the banana bread rest for approximately 2 minutes.
During this time, the crumb will finish setting and become easier to slice.
Avoid cutting it immediately while it is extremely hot, as the soft interior may fall apart.
Step 8: Slice and Enjoy! 🍰
Use a small knife to cut a generous slice of warm banana bread.
Gently lift the slice with a fork.
You should see a tender, moist interior with tiny pieces of walnuts, almonds, and seeds throughout.
The banana flavor is naturally sweet, while the nuts add a delicious contrast in texture.
Enjoy it warm directly from the bowl!
💡 8 Tips for Perfect Microwave Banana Bread
1. Use very ripe bananas. They provide natural sweetness and moisture.
2. Mash the bananas thoroughly. Large chunks can cause uneven texture.
3. Choose thick Greek yogurt. Watery yogurt can make the batter too loose.
4. Don’t skip the baking powder. It helps the cake rise and prevents an overly dense texture.
5. Use a microwave-safe bowl with enough space. The batter needs room to expand.
6. Cook in short intervals. Microwave power varies, and overcooking can quickly make the cake rubbery.
7. Chop the nuts into small pieces. This creates a more even distribution throughout the cake.
8. Allow the cake to rest before slicing. A short cooling period helps the soft crumb hold together.
🍫 Delicious Variations
1. Chocolate Banana Nut Bread
Add 1 tablespoon unsweetened cocoa powder and 1 tablespoon dark chocolate chips.
The combination of banana, chocolate, and walnuts is incredibly delicious!
2. Peanut Butter Banana Bread
Stir 1 tablespoon creamy peanut butter into the batter before cooking.
Top with chopped peanuts for extra crunch.
3. Cinnamon Walnut Banana Bread
Add ½ teaspoon cinnamon and an extra tablespoon of chopped walnuts.
This variation has a warm, comforting flavor.
4. Almond Vanilla Banana Bread
Use sliced almonds, vanilla extract, and a small pinch of cinnamon.
The result is fragrant, nutty, and lightly sweet.
5. Extra Seed Banana Bread
Replace some of the walnuts with sunflower seeds, pumpkin seeds, and chia seeds.
This creates a delicious seed-packed variation.
🍯 What to Serve With Banana Nut Bread
This warm microwave banana bread tastes wonderful with:
- A spoonful of Greek yogurt
- Natural peanut butter
- Almond butter
- Fresh banana slices

🧊 How to Store and Reheat
Refrigerator: Allow the banana bread to cool, then transfer it to an airtight container. Refrigerate for up to 3 days.
Freezer: Wrap individual portions tightly and freeze for up to 2 months for best quality.
Reheating: Place a slice on a microwave-safe plate and heat for 15–25 seconds, checking until warmed through.
Avoid reheating for too long because microwave cakes can become tough or dry.
❓ Frequently Asked Questions
Can I really make banana bread in the microwave?
Yes!
A microwave can cook a banana-based cake quickly without an oven.
However, the finished texture is different from traditional baked banana bread. It is generally softer, moister, and less browned.
Can I make this without regular flour?
Absolutely!
This recipe uses a small amount of oat flour instead of wheat flour.
You can make oat flour by blending rolled oats into a fine powder.
Can I skip the oat flour?
You can experiment with a flourless banana-and-egg mixture, but the result will be more like a soft banana custard than traditional banana bread.
Oat flour helps absorb moisture and gives the cake a more stable crumb.
Can I use regular yogurt instead of Greek yogurt?
Yes, but regular yogurt is usually thinner.
If your yogurt is watery, strain it first or slightly reduce the amount.
Why is my banana bread rubbery?
Overcooking is one of the most common reasons.
Microwaves cook very quickly, so check the cake frequently near the end.
Too much egg relative to the other ingredients can also produce a firmer, eggier texture.
Why is the center still wet?
The bowl may be too deep, the batter may be too thick, or the microwave may have lower power.
