What You’ll Need (Ingredients)

• 3 medium very ripe bananas (about 1 1/4 cups mashed)
• 2 large eggs, room temperature
• 1 cup plain Greek yogurt (2% or 0% both work)
• 1/4 cup melted coconut oil or light olive oil
• 1/3 to 1/2 cup light brown sugar or coconut sugar (adjust to taste) or 1/3 cup granulated sweetener
• 2 teaspoons pure vanilla extract
• 1 1/2 cups white whole wheat flour or oat flour (spooned and leveled)
• 1/2 cup vanilla or unflavored whey protein powder (or plant protein; see notes)
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon fine sea salt
• 1 1/2 teaspoons ground cinnamon
• Optional mix-ins: 1/2 cup chopped walnuts or pecans, 1/3 cup dark chocolate chips, 2 tablespoons chia or flax seeds

How to Make It – Instructions

1. Prep the pan and oven: Preheat to 350°F (175°C).Line a 9×5-inch loaf pan with parchment, leaving overhang for easy lifting. Lightly grease the sides.
2. Mash the bananas: In a large bowl, mash bananas until mostly smooth with a few small lumps. You want texture, not banana soup.
3. Whisk the wet ingredients: Add eggs, Greek yogurt, oil, sugar/sweetener, and vanilla.Whisk until glossy and cohesive.
4. Mix the dry ingredients: In a separate bowl, whisk flour, protein powder, baking soda, baking powder, salt, and cinnamon. This prevents clumps and ensures even rise.
5. Combine smartly: Add dry to wet. Fold with a spatula until just combined.If adding nuts/chocolate/seeds, fold them in now. Do not overmix unless you like rubbery bread (you don’t).
6. Fill and level: Pour batter into the prepared pan. Smooth the top.Optional: sprinkle a few oats or extra cinnamon for that “I know what I’m doing” vibe.
7. Bake: 45–60 minutes, depending on your oven and protein type. Tent with foil at the 40-minute mark if browning too fast. A tester should come out mostly clean with a few moist crumbs.
8. Cool like you mean it: Let rest in the pan 10–15 minutes.Lift out using parchment and cool on a rack for at least 45 minutes before slicing. Yes, waiting is hard. Yes, it’s worth it.
9. Slice and serve: Cut into 10–12 slices.Spread with almond butter, Greek yogurt, or a little honey if you’re feeling fancy.

Storage Instructions

• Room temperature: Store in an airtight container for up to 2 days. Keep it wrapped to retain moisture.
• Refrigerator: Up to 5–6 days. Warm slices in the microwave for 15–20 seconds to revive the crumb.
• Freezer: Slice, wrap individually, and freeze up to 3 months.Thaw overnight in the fridge or toast from frozen.

Health Benefits

• Protein for satiety and recovery: Greek yogurt and protein powder deliver a meaningful protein punch that helps keep you full and supports muscle repair.
• Fiber from bananas and whole grains: Aids digestion, steadies energy, and helps avoid snack attacks an hour later.
• Healthy fats, smart carbs: Coconut or olive oil plus complex carbs provide long-lasting fuel, not a sugar crash.
• Micronutrients that matter: Bananas bring potassium and vitamin B6; nuts add magnesium and omega-3 ALA (if using walnuts).
• Lower sugar than typical loaves: Leaning on banana sweetness means you don’t need a cup of sugar to make it taste great.

Avoid These Mistakes

• Using unripe bananas: Green or firm bananas won’t mash well and won’t deliver the sweetness or flavor you want. Spotty-brown is the move.
• Overmixing the batter: This activates gluten and makes a tough loaf. Fold gently until you see no dry streaks—then stop.
• Too much protein powder: More isn’t more.Overloading can dry out the bread. Stick to about 1/2 cup and balance with yogurt.
• Skipping the cool-down: Slicing hot bread compresses the crumb and releases steam, drying it out. Patience > crumbs on the cutting board.
• Wrong pan size: A smaller pan can cause overflow and raw centers.Use a 9×5 or adjust baking time for an 8.5×4.5 pan.

Different Ways to Make This

• Gluten-free: Swap the flour with a 1:1 gluten-free baking blend or oat flour. If using oat flour, add 1 extra tablespoon oil for tenderness.
• Dairy-free: Use a thick coconut or almond milk yogurt and a plant-based protein powder. Choose dairy-free chocolate if adding chips.
• No added sugar: Rely on bananas and use a zero-calorie sweetener.For deeper flavor, add an extra teaspoon of vanilla and a pinch more cinnamon.
• Breakfast boost: Stir in 2 tablespoons chia or ground flax and top slices with peanut butter. Now it’s a legit meal.
• Spice route: Add 1/4 teaspoon nutmeg and 1/2 teaspoon cardamom for a café-level profile. Your kitchen will smell like a candle store—in a good way.
• Muffin mode: Bake in a lined muffin tin at 350°F for 18–22 minutes.Great for grab-and-go and portion control, IMO.

FAQ

Can I use casein or collagen instead of whey?

Casein works but absorbs more liquid; reduce flour by 2–3 tablespoons or add 2–3 tablespoons extra yogurt. Collagen doesn’t behave like flour and won’t add structure; it can make the loaf gummy. If using collagen, limit to 2 tablespoons and keep the whey or plant protein as the main powder.

How do I prevent a dry loaf?

Measure flour correctly (spoon and level), don’t overbake, and keep the protein powder to about 1/2 cup.

If your batter seems overly thick, add 1–2 tablespoons milk. Also, use fully ripe bananas—they’re moisture bombs.

Can I reduce the oil?

Yes. Cut to 2 tablespoons and add 2 tablespoons applesauce or extra yogurt.

Texture stays moist, but flavor is slightly less rich. Fair trade-off if you’re trimming calories.

What if I only have regular all-purpose flour?

Use it 1:1. The loaf will be a bit lighter and less nutty in flavor.

Keep everything else the same.

Do I need a stand mixer?

Nope. A whisk, a spatula, and two bowls are enough. Overbeating is your enemy here, so the low-tech route is actually safer.

How much protein per slice?

Depends on your protein powder, but typically 9–13 grams per slice (12 slices per loaf).

If you add nuts or seeds, that number nudges higher. FYI, muffins tend to concentrate macros similarly per portion.

Can I add blueberries?

Yes, 3/4 cup fresh or frozen (no thawing). Toss them in a teaspoon of flour to prevent sinking, and fold gently at the end.

Why did my loaf sink in the middle?

Usually underbaking or too much leavening.

Check your oven temp with a thermometer, and bake until that tester is mostly clean. Also, resist opening the door early; warm air escapes and the center collapses like a bad alibi.
