Ingredients
For the Banana Bread:
- 3-4 medium very ripe bananas (about 1 ½ cups mashed)
- 1 large egg
- ¼ cup (60 ml) neutral oil (such as vegetable, canola, or melted coconut oil)
- ¼ cup (60 ml) milk (any kind, dairy or non-dairy)
- 1 tsp (5 ml) vanilla extract
- ½ cup (60 g) vanilla or unflavored protein powder
- 1 ½ cups (180 g) all-purpose flour
- ½ cup (100 g) granulated sugar (or brown sugar for deeper flavor)
- 1 tsp (5 g) baking soda
- ½ tsp (2.5 g) salt
- 1 cup (170 g) semi-sweet chocolate chips (or dark chocolate chips)
Ingredient Notes
- Ripe Bananas: The riper the bananas (brown spots are good!), the sweeter and more flavorful your bread will be. They also provide essential moisture.
- Protein Powder: Vanilla protein powder works wonderfully here, complementing the banana and chocolate flavors. If using unflavored protein powder, you might want to add an extra ¼ teaspoon of vanilla extract. Whey or plant-based protein powders both work well, but keep in mind that some plant-based powders can absorb more liquid, so you might need to add a splash more milk if the batter seems too thick.
- Oil: A neutral oil ensures the banana and chocolate flavors shine through. Melted butter can also be used for a richer taste.
- Sugar: Granulated sugar provides sweetness, but brown sugar can add a lovely molasses note and extra moisture. Adjust to your sweetness preference.
- Chocolate Chips: Semi-sweet is classic, but dark chocolate chips offer a richer flavor and slightly less sugar, making the bread even healthier.
Equipment You’ll Need
- 9×5 inch (23×13 cm) loaf pan
- Large mixing bowl
- Medium mixing bowl
- Whisk
- Fork or potato masher
- Rubber spatula or wooden spoon
- Measuring cups and spoons
- Wire cooling rack
How to Make High-Protein Banana Chocolate Chip Bread

- Preheat Oven & Prepare Pan: Preheat your oven to 350°F (175°C). Lightly grease and flour a 9×5 inch (23×13 cm) loaf pan, or line it with parchment paper for easy removal.
- Mash Bananas: In a large mixing bowl, mash the very ripe bananas with a fork or potato masher until mostly smooth with a few small lumps remaining.
- Combine Wet Ingredients: To the mashed bananas, add the egg, oil, milk, and vanilla extract. Whisk everything together until well combined and smooth.
- Combine Dry Ingredients: In a separate medium mixing bowl, whisk together the protein powder, all-purpose flour, granulated sugar, baking soda, and salt. Ensure there are no clumps of protein powder.
- Combine Wet and Dry: Pour the dry ingredients into the wet ingredients. Using a rubber spatula or wooden spoon, mix until just combined. Be careful not to overmix; a few streaks of flour are okay. Overmixing can lead to a tough bread.
- Fold in Chocolate Chips: Gently fold in the chocolate chips until they are evenly distributed throughout the batter.
- Pour into Pan & Bake: Pour the batter into the prepared loaf pan and spread it evenly. Bake for 50-60 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. The top should be golden brown.
- Cool: Once baked, remove the loaf pan from the oven and let it cool in the pan for 10-15 minutes. Then, carefully invert the bread onto a wire cooling rack to cool completely before slicing. This prevents the bottom from getting soggy.

Pro Tips for the Best Results
- Use Very Ripe Bananas: This is key for natural sweetness, intense banana flavor, and moistness. Don’t use under-ripe bananas.
- Measure Flour Correctly: Spoon the flour into your measuring cup and then level it off with a straight edge. Scooping directly from the bag can compact the flour, leading to too much flour and a dry bread.
- Don’t Overmix: Mix the wet and dry ingredients until just combined. Overmixing develops the gluten in the flour, resulting in a tough, dense loaf instead of a tender one.
- Don’t Overbake: Keep an eye on your bread. Once the toothpick comes out clean, it’s done. Overbaking can dry out the bread.
- Cool Completely: Resist the urge to slice into the warm bread immediately. Letting it cool completely allows the structure to set and the flavors to meld, resulting in a better texture.
- Choose Your Protein Powder Wisely: Some protein powders can alter texture. If your powder is known to be very absorbent, you might need a tablespoon or two more milk to achieve the right batter consistency.
Common Mistakes to Avoid
- Using Under-Ripe Bananas: This will result in a less flavorful and less sweet bread. Wait until your bananas have plenty of brown spots.
- Overmixing the Batter: As mentioned, this is a common culprit for tough, dry banana bread. Mix until just combined.
- Not Greasing the Pan Properly: Ensure your loaf pan is well-greased and floured (or lined with parchment) to prevent sticking, especially with the added weight of chocolate chips and protein.
- Baking at Too High a Temperature: While 350°F (175°C) is standard, if your oven runs hot, you might need to reduce the temperature slightly or tent the bread with foil if the top browns too quickly.
- Adding Too Much Protein Powder: Stick to the recommended amount. Too much protein powder can make the bread dry or give it an unpleasant texture.
Variations & Substitutions
- Nutty Addition: Add ½ cup of chopped walnuts or pecans along with the chocolate chips for extra crunch and flavor.
- Spiced Banana Bread: Incorporate 1 teaspoon of ground cinnamon or a pinch of nutmeg for a warm, spiced variation.
- Different Protein Flavors: Try chocolate protein powder for a double chocolate banana bread, or a peanut butter flavored protein powder for a delicious twist.
- Sweetener Swap: You can replace granulated sugar with an equal amount of coconut sugar or use ½ cup of maple syrup or honey, reducing the milk by 2 tablespoons if using liquid sweeteners.
- Flour Alternatives: For a gluten-free option, use a 1:1 gluten-free baking flour blend. For a healthier fiber boost, swap ½ cup of all-purpose flour for whole wheat flour.
Serving Suggestions
This High-Protein Banana Chocolate Chip Bread is fantastic on its own, but here are some ideas to make it even better:
- For Breakfast: Serve a slice with a smear of almond butter or peanut butter for an extra protein kick, or alongside Greek yogurt and fresh berries.
- As a Snack: Enjoy a slice with a cup of coffee or tea.
- Warm & Indulgent: Heat a slice slightly in the microwave and serve with a scoop of vanilla ice cream or a drizzle of warm caramel sauce for a dessert-like treat.
Storage & Reheating
- Countertop: Store leftover banana bread in an airtight container at room temperature for up to 2-3 days.
- Refrigerator: For longer storage, keep it in an airtight container in the refrigerator for up to 5-7 days.
- Freezer: This bread freezes beautifully! Once completely cooled, wrap the entire loaf tightly in plastic wrap, then in aluminum foil. Alternatively, slice the bread and wrap individual slices. Freeze for up to 3 months.
- Reheating: Thaw frozen bread at room temperature or in the refrigerator. Reheat individual slices in the microwave for 15-30 seconds, or in a toaster oven for a few minutes until warmed through.
FAQ
Q: Can I use frozen bananas for this recipe?
A: Yes! Thaw frozen bananas completely, drain any excess liquid, then mash and use as directed. The texture might be slightly softer, but the flavor will be great.
Q: My bread turned out dry, what went wrong?
A: This is usually due to overmixing the batter, overbaking, or potentially using a protein powder that absorbs a lot of moisture. Ensure you mix just until combined and check for doneness with a toothpick.
Q: Can I reduce the sugar amount?
A: Yes, you can reduce the granulated sugar to ¼ cup if your bananas are very ripe and sweet, or if you prefer a less sweet bread. The chocolate chips will also add sweetness.
Q: What kind of protein powder works best?
A: Vanilla or unflavored whey protein powder typically yields the best texture and flavor. Plant-based protein powders can also work, but some may result in a slightly denser texture.
Q: How do I know when the bread is done baking?
A: The top will be golden brown, and a wooden skewer or toothpick inserted into the center of the loaf should come out clean, without any wet batter clinging to it.
