Moist, easy to make in one bowl, and freezer-friendly, this recipe is a game changer for anyone looking to add more protein without sacrificing flavor.
Ingredients Overview
Let’s look at the star ingredients that make this banana bread delicious and nourishing.
Ripe Bananas
Overripe bananas bring natural sweetness, moisture, and classic banana bread flavor. The riper, the better.
-
Use 2–3 medium bananas (about 1¼ cups mashed)
Protein Powder
Unflavored or chocolate protein powder adds muscle-building protein. Use a high-quality whey, plant-based, or casein powder.
-
Stick with ¼ to ½ cup—too much can dry out the bread
Greek Yogurt
Adds moisture, protein, and tang that balances the sweetness. Use plain, non-fat, or full-fat depending on your goals.
Cocoa Powder
Unsweetened cocoa powder makes this bread deeply chocolatey. Use Dutch-processed for smoother, richer flavor or natural cocoa for boldness.
Whole Wheat Flour
Adds fiber and structure without heaviness. Can also use oat flour or a 50/50 mix with all-purpose.
Eggs
Bind the bread and add structure. You can substitute with flax eggs for a plant-based option.
Maple Syrup or Honey
A touch of natural sweetener balances the cocoa. You can skip or reduce depending on how sweet your bananas are.
Baking Soda & Vanilla
Leavening and depth of flavor.
Chocolate Chips (Optional)
Dark chocolate chips or chopped chunks take this bread to the next level with melty goodness in every bite.
Step-by-Step Instructions
This recipe takes less than 15 minutes to prep and under an hour to bake. One bowl, no mixer needed.
1. Preheat and Prep
-
Preheat oven to 350°F (175°C)
-
Grease or line a 9×5 inch loaf pan
2. Mash the Bananas
In a large bowl, mash 2–3 ripe bananas with a fork until mostly smooth.
3. Add Wet Ingredients
To the mashed bananas, add:
-
2 large eggs
-
½ cup plain Greek yogurt
-
¼ cup maple syrup or honey
-
1½ tsp vanilla extract
Whisk until smooth.
4. Add Dry Ingredients
Sprinkle over the wet mix:
-
½ cup chocolate or unflavored protein powder
-
½ cup unsweetened cocoa powder
-
¾ cup whole wheat flour (or oat flour)
-
1 tsp baking soda
-
¼ tsp salt
Gently fold together with a spatula until just combined. Batter will be thick.
5. Fold in Extras
Optional but delicious:
-
½ cup dark chocolate chips
-
¼ cup chopped walnuts or pecans
Stir in gently.
6. Bake
Pour batter into the prepared loaf pan. Sprinkle a few extra chocolate chips on top if desired.
Bake for 45–55 minutes, or until a toothpick inserted into the center comes out mostly clean (some chocolate streaks are fine).
7. Cool and Slice
Cool in pan for 10–15 minutes, then transfer to a wire rack. Let it cool completely before slicing—this helps the texture set and keeps slices clean.

FAQs About High Protein Chocolate Banana Bread
1. Can I use vanilla protein powder instead of chocolate?
Yes. Just use unsweetened cocoa powder as listed and add your vanilla powder. It will be sweeter and lighter in flavor.
2. Can I make this dairy-free?
Yes. Use coconut or almond yogurt, plant-based protein, and dairy-free chocolate chips.
3. How do I store it?
Store in an airtight container at room temp for 2 days, or in the fridge for up to 5 days. Freeze slices for up to 3 months.
4. Why is my bread dry or crumbly?
Too much protein powder or flour can dry out the batter. Use a scale or fluff/spoon your flour when measuring.
5. Can I make muffins instead?
Yes! Bake in a muffin tin at 350°F for 18–22 minutes. Check with a toothpick for doneness.
6. What kind of protein powder works best?
Whey, casein, or plant-based all work, but whey may lead to a slightly fluffier texture. Avoid collagen powder—it doesn’t bake the same.
7. Can I skip the sweetener?
Yes—if your bananas are extra ripe and you’re adding chocolate chips, it will still be sweet enough for many tastes.
