Why I Love This Recipe
I started making this banana bread when I wanted something that tasted like a treat but kept me full for hours. After a few test batches, this version became the winner. The bananas keep it soft, the oats add a nice texture, and the Greek yogurt and protein powder make every slice much more filling than regular banana bread. Now I make a loaf almost every week because it is easy, freezes well, and tastes just as good the next day.
What makes this recipe special:
- Soft and moist every time.
- Naturally sweet from ripe bananas.
- High in protein without tasting dry.
- Great for meal prep.
- Easy to customize with nuts or chocolate chips.
- Made with simple pantry ingredients.
What You’ll Need
- 3 medium ripe bananas, mashed (about 1½ cups)
- 2 large eggs
- ¾ cup plain nonfat Greek yogurt
- ¼ cup honey
- 1 teaspoon vanilla extract
- 1½ cups oat flour
- 1 scoop (about 30 grams) vanilla protein powder
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ¼ cup mini dark chocolate chips (optional)
Why This Recipe Works (Quick Science)
Bananas add moisture because they are full of natural sugars and water. Greek yogurt brings extra protein while helping keep the bread soft. Eggs hold everything together. Baking powder and baking soda create bubbles that help the loaf rise. Oat flour makes a tender crumb, while protein powder adds protein without making the bread too heavy when used in the right amount.

- Mash the bananas until almost smooth for the best texture.

Recipe
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Line one 9×5-inch loaf pan with parchment paper.
Step 2: Mash the Bananas
Place 3 medium ripe bananas into a large mixing bowl. Mash them with a fork until mostly smooth with only a few small lumps.
Step 3: Mix the Wet Ingredients
Add 2 large eggs, ¾ cup plain nonfat Greek yogurt, ¼ cup honey, and 1 teaspoon vanilla extract to the mashed bananas. Whisk until smooth and creamy.
Step 4: Add the Dry Ingredients
Add 1½ cups oat flour, 1 scoop vanilla protein powder, 1 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon ground cinnamon, and ¼ teaspoon salt. Fold gently until no dry spots remain. Fold in ¼ cup mini dark chocolate chips if using.
Step 5: Fill the Pan
Pour the batter into the prepared loaf pan. Spread the batter evenly with a spatula.
Step 6: Bake
Bake at 350°F (175°C) for 50 to 55 minutes. The bread is done when a toothpick inserted into the center comes out mostly clean with a few moist crumbs.
Step 7: Cool and Slice
Let the bread cool in the pan for 10 minutes. Lift it out onto a cooling rack and cool completely before slicing into 10 slices.
