Ingredients Overview
Here’s how each ingredient contributes to making this high-protein banana bread fluffy, moist, and full of nutritional value.
Overripe Bananas
The riper, the better. Brown, spotty bananas add moisture, natural sweetness, and a rich banana flavor. You’ll need about 1 cup mashed bananas (2–3 medium bananas).
Protein Powder
The star protein booster. Use a high-quality whey, plant-based, or collagen protein powder (vanilla works best) that you enjoy the taste of.
-
Pro Tip: Not all protein powders bake the same—choose one that doesn’t dry out the batter or use a blend specifically designed for baking.
Oats or Oat Flour
Adds fiber, texture, and structure. You can use:
-
Oat flour for a finer crumb
-
Rolled oats blended into flour for a budget-friendly option
Gluten-free if needed.
Eggs
Act as a binder and add richness. Eggs also provide their own protein and help create lift.
Greek Yogurt
Adds moisture and creaminess while also boosting protein. Use full-fat or 2% plain Greek yogurt.
Baking Powder & Baking Soda
These leaveners help the bread rise and give it a fluffy interior.
Cinnamon & Vanilla
Classic flavor enhancers. Cinnamon complements the banana, and vanilla brings a sweet warmth.
Maple Syrup or Honey
Used in moderation for extra sweetness—especially helpful if your bananas aren’t overly ripe.
Optional Add-ins
-
Chopped walnuts or pecans for crunch
-
Dark chocolate chips for indulgence
-
Flaxseed or chia seeds for added fiber and omega-3s

FAQ
1. Can I use any protein powder?
Not exactly. Whey, plant-based, and collagen protein all behave differently. Choose one labeled “bakeable” or that you’ve had success with in other recipes. Avoid gritty or highly flavored types.
2. Why is my protein banana bread dry?
It’s likely due to overbaking or too much protein powder. Check your oven temp, and consider using Greek yogurt or applesauce for added moisture.
3. Can I freeze this banana bread?
Yes! Slice, wrap individually, and freeze in a zip bag. Thaw at room temp or microwave for 20–30 seconds.
4. How long does it last?
Stored in the fridge, it lasts up to 5 days. It’s best slightly warmed before eating.
5. Can I make this into muffins?
Absolutely. Pour into a greased or lined muffin tin and bake at 350°F for 18–22 minutes.
6. Is this good for weight loss?
It can be! With balanced macros, fiber, and no refined sugars, it keeps you full longer and supports energy without spikes. Just watch portion sizes.
7. What’s a good topping for this?
Try almond butter, Greek yogurt, or a thin layer of cream cheese. Even a pat of butter or a sprinkle of cinnamon makes it irresistible.
