Why I Love This Recipe
Banana bread has always been one of those recipes I make when I see a couple of ripe bananas sitting on the counter. Adding pumpkin turned out to be an easy way to make it even softer without adding lots of oil.
Then I started adding Greek yogurt and protein powder. The result is still very much banana bread—not a dry “protein snack” pretending to be banana bread. The pumpkin, banana, and yogurt help balance the protein powder and keep the crumb tender.
Here’s why it has become such a useful recipe:
- It has plenty of protein. Eggs, Greek yogurt, and protein powder all help.
- It stays moist. Pumpkin and mashed banana add moisture naturally.
- It is simple. You only need bowls, a whisk, and a loaf pan.
- It freezes well. Individual slices are easy to save for later.
- It is easy to change. Add chocolate chips, nuts, or leave both out.
- It tastes like fall without being overly pumpkin-heavy. You still get plenty of banana flavor.
What You’ll Need
- 1 cup (240 g) pumpkin puree — plain pumpkin, not pumpkin pie filling
- 1 cup (225 g) mashed very ripe banana — about 2 large bananas
- 2 large eggs
- 1/2 cup (120 g) plain Greek yogurt
- 1/4 cup (60 ml) maple syrup
- 2 tablespoons (30 ml) melted coconut oil, cooled slightly
- 1 teaspoon vanilla extract
- 1 cup (100 g) old-fashioned rolled oats, blended into oat flour
- 3/4 cup (90 g) all-purpose flour
- 1/2 cup (50 g) vanilla protein powder
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 2 teaspoons ground cinnamon
- 1/2 teaspoon pumpkin pie spice
- 1/2 teaspoon salt
- 1/3 cup (60 g) mini chocolate chips, plus a few extra for the top if desired
Pro Tips
- Use very ripe bananas. Bananas covered in brown spots are sweeter and easier to mash.
- Check your protein powder. Some protein powders absorb much more liquid than others. Whey or a whey-casein blend usually gives a softer result than many plant-based powders.
- Don’t overmix. Once the flour goes into the wet ingredients, mix only until you no longer see dry streaks.
- Use pumpkin puree, not pumpkin pie filling. Pie filling already contains sugar and spices and will change the recipe.
- Cool before slicing. Protein-rich quick breads can seem gummy when they’re still hot. Give the loaf at least 30 minutes to set.
Tools You’ll Need
- 9×5-inch loaf pan
- Parchment paper
- Nonstick cooking spray
- Large mixing bowl
- Medium mixing bowl
- Whisk
- Silicone spatula
- Measuring cups
- Measuring spoons
- Kitchen scale, optional but helpful
- Small blender or food processor
- Wire cooling rack
- Serrated knife
Substitutions and Variations
Protein powder: Vanilla whey protein works especially well. An unflavored powder can also work, but you may want a little extra vanilla. Plant-based protein tends to absorb more moisture, so the loaf may be denser.
Greek yogurt: Use plain skyr or another thick, high-protein yogurt.
Maple syrup: Honey can be used in the same amount.
Coconut oil: Melted butter or a neutral oil works well.
Chocolate chips: Leave them out, use dark chocolate chips, or replace them with 1/3 cup chopped walnuts or pecans.
More spice: Add another 1/2 teaspoon pumpkin pie spice for a stronger fall flavor.
Make Ahead Tips
You can blend the oats into oat flour and combine all the dry ingredients a day ahead. Keep them covered at room temperature.
The entire loaf can also be baked ahead. Once completely cool, wrap it well and refrigerate it. The flavor and texture are still great the next day.
High Protein Banana Pumpkin Bread Recipe and Instructions
Step 1: Prepare the Pan and Oven
Heat the oven to 350°F (175°C). Lightly coat a 9×5-inch loaf pan with nonstick cooking spray, then line it with parchment paper, leaving enough parchment hanging over the sides to lift out the finished bread.
Step 2: Make the Oat Flour
Place 1 cup (100 g) old-fashioned rolled oats in a small blender or food processor. Blend until they become a fine, flour-like powder. You should have about 1 cup of freshly ground oat flour.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, add 1 cup (240 g) pumpkin puree, 1 cup (225 g) mashed very ripe banana, 2 large eggs, 1/2 cup (120 g) plain Greek yogurt, 1/4 cup (60 ml) maple syrup, 2 tablespoons (30 ml) melted and slightly cooled coconut oil, and 1 teaspoon vanilla extract.
Whisk until everything looks smooth and evenly combined. A few tiny banana pieces are completely fine.
Step 4: Combine the Dry Ingredients
In a medium bowl, whisk together the 1 cup oat flour made from the 1 cup (100 g) rolled oats, 3/4 cup (90 g) all-purpose flour, 1/2 cup (50 g) vanilla protein powder, 1 teaspoon baking soda, 1 teaspoon baking powder, 2 teaspoons ground cinnamon, 1/2 teaspoon pumpkin pie spice, and 1/2 teaspoon salt.
Whisk well so the baking soda, baking powder, spices, and protein powder are spread evenly through the flour.
Step 5: Make the Batter
Pour the dry mixture from Step 4 into the wet pumpkin-banana mixture from Step 3.
Using a silicone spatula, gently fold them together just until no large streaks of dry flour remain. Don’t beat or heavily stir the batter.
Step 6: Fold in the Chocolate Chips
Add 1/3 cup (60 g) mini chocolate chips to the finished pumpkin-banana batter. Fold gently with the spatula just until the chips are spread throughout.
Step 7: Fill the Loaf Pan
Scrape all the batter into the prepared 9×5-inch loaf pan. Smooth the top gently with your spatula. Sprinkle a few extra mini chocolate chips over the surface if desired.
Step 8: Bake
Place the loaf pan in the 350°F (175°C) oven and bake for 50–60 minutes.
The bread is ready when the center looks set and a toothpick inserted near the middle comes out with a few moist crumbs rather than wet batter. If the top is browning too quickly, loosely cover it with foil during the final 10–15 minutes.
Step 9: Cool, Slice, and Serve
Let the bread cool in its pan for 15 minutes. Use the parchment to lift it onto a wire rack and cool for at least another 15 minutes before slicing.
Cut the loaf into 10 slices with a serrated knife. Slice and serve.
Why This Recipe Works (Quick Science)
Banana and pumpkin hold moisture. Both ingredients contain plenty of water and fiber. That helps keep the bread soft even with protein powder in the batter.
Greek yogurt adds protein and tenderness. Its moisture keeps the crumb softer, while its acidity works with the baking soda to help the loaf rise.
Eggs give the loaf structure. Their proteins set during baking and help hold everything together.
Oat flour adds fiber and softness. Grinding oats gives the bread structure without making it as firm as a loaf made entirely with wheat flour.
Protein powder needs moisture. Protein powder can make baked goods dry when too much is used. Pumpkin, banana, yogurt, eggs, and maple syrup provide enough liquid to help balance it.
Baking soda and baking powder work together. They produce gas bubbles that expand in the oven, giving this heavier, high-protein batter a better rise.
Macros Information
Approximate nutrition per slice when the loaf is cut into 10 slices:
- Calories: 220
- Protein: 10 g
- Carbohydrates: 32 g
- Fat: 7 g
- Fiber: 4 g
- Sugar: 12 g
These are estimates. The exact macros can change quite a bit depending on your protein powder, Greek yogurt, chocolate chips, and other brands.
For higher protein, serve a slice with Greek yogurt, cottage cheese, or a glass of milk rather than adding a large amount of extra protein powder to the batter.
Common Mistakes
Using pumpkin pie filling: It isn’t the same as plain pumpkin puree. Use 100% pumpkin.
Adding too much protein powder: More isn’t always better. Extra powder can quickly turn moist banana bread dry and rubbery.
Overmixing the batter: Stirring too much after adding flour can create a tougher loaf. Fold gently and stop when the flour disappears.
Using firm bananas: Very ripe, heavily spotted bananas give you more sweetness, moisture, and banana flavor.
Cutting the loaf while it’s hot: The center continues to set as the bread cools. Cutting immediately can make even a properly baked loaf look gummy.
Overbaking: Start checking around 50 minutes. A toothpick with a few moist crumbs is fine.
What to Serve With
For breakfast, try a slice with plain Greek yogurt and fresh berries. A spoonful of peanut or almond butter also adds richness and more protein.
For a simple snack, pair it with milk, coffee, or tea. You can also warm a slice for a few seconds and add a thin layer of butter.
Leftovers and Storage
Let the bread cool completely before storing it. Keep it in an airtight container at room temperature for up to 2 days.
For longer storage, refrigerate it for up to 5 days. The refrigerator can make bread feel a little firm, so warming a slice for 10–15 seconds in the microwave helps bring back its soft texture.
For freezing, wrap individual slices tightly and place them in a freezer-safe bag or container. Freeze for up to 3 months. Thaw overnight in the refrigerator or for an hour or two at room temperature.
FAQ
Can I use canned pumpkin?
Yes. Canned 100% pumpkin puree is perfect for this recipe. Just don’t use pumpkin pie filling.
What protein powder works best?
Vanilla whey protein or a whey-casein blend usually gives a soft texture. Different brands absorb liquid differently, so results can vary.
Can I make it without chocolate chips?
Absolutely. Simply leave them out, or replace the 1/3 cup chocolate chips with chopped walnuts or pecans.
Why did my protein banana bread turn out dry?
The most common causes are too much protein powder, too much flour, or baking too long. Weighing your dry ingredients is the easiest way to avoid accidentally adding too much.
How do I know when it’s done?
The top should look set and lightly browned. Insert a toothpick near the center. A few moist crumbs are good, but there shouldn’t be wet batter.
Can I use pumpkin pie spice instead of cinnamon?
Yes. For a stronger pumpkin-spice flavor, replace the 2 teaspoons cinnamon and 1/2 teaspoon pumpkin pie spice with about 2 1/2 teaspoons pumpkin pie spice.
Can I freeze the whole loaf?
Yes. Cool it completely, wrap it tightly, and freeze it for up to 3 months. Slicing before freezing is more convenient because you can thaw one serving at a time.
