Ingredients

• 3 large bananas, very ripe, mashed — use spotty brown bananas for max sweetness
• 75 g plain Greek yogurt — full-fat gives best moisture
• 60 ml milk of choice — dairy or unsweetened plant milk both work
• 80 ml honey or maple syrup — pick your preferred natural sweetener
• 60 ml melted coconut oil or melted butter — cool slightly so it doesn’t cook the eggs
• 2 large eggs, room temperature — room temp helps batter mix evenly
• 5 ml vanilla extract — real vanilla adds deeper flavor
• 120 g chocolate protein powder (whey or plant-based) — choose a brand you like the taste of
• 120 g all-purpose flour — spoon and level to avoid dense bread
• 30 g unsweetened cocoa powder — Dutch-process gives richer chocolate flavor
• 5 g baking powder — check it’s fresh for proper rise
• 3 g baking soda — balances the banana and yogurt acidity
• 3 g fine sea salt — enhances the chocolate and banana flavors
• 60 g dark chocolate chips — 60–70% cacao melts into fudgy pockets
• 30 g chopped nuts, optional — walnuts or pecans add crunch and healthy fats

Step-by-Step Method

Preheat the Oven & Prepare the Pan

Preheat the oven to 350°F (175°C) so it reaches temperature before baking. Lightly grease a 9×5-inch loaf pan with nonstick spray or line it with parchment paper, leaving some overhang for easy lifting.

Set the pan aside while you prepare the batter. This prevents sticking and helps the loaf release cleanly.

Combine the Dry Ingredients

Whisk together the all-purpose flour, chocolate protein powder, cocoa powder, baking powder, baking soda, and fine sea salt in a medium bowl. Break up any clumps, especially in the protein powder and cocoa.

Mix until the color is uniform. This guarantees the leavening agents and salt are evenly distributed throughout the batter.

Mash the Bananas

Place the very ripe bananas in a separate medium bowl. Mash them thoroughly with a fork or potato masher until mostly smooth.

Leave a few small lumps if you like a bit of texture. Well-mashed bananas help sweeten and moisten the bread evenly, contributing to a tender crumb and consistent flavor.

Whisk in the Wet Ingredients

Add Greek yogurt, milk, honey or maple syrup, melted coconut oil or butter, eggs, and vanilla extract to the mashed bananas.

Whisk until the mixture looks smooth and cohesive, with no visible streaks of egg or oil.

Make certain the melted fat isn’t too hot so it doesn’t scramble the eggs. Set this wet mixture aside.

Fold Dry into Wet Gently

Pour the dry ingredients into the bowl of wet ingredients. Use a rubber spatula to fold the mixture together slowly.

Scrape the sides and bottom of the bowl to incorporate all the flour. Stop mixing as soon as no dry pockets remain.

Avoid overmixing to keep the banana bread soft and not tough.

Stir in Chocolate Chips & Nuts

Fold in the dark chocolate chips and chopped nuts, if using, with a few gentle strokes.

Distribute them evenly throughout the batter without vigorously stirring.

Overmixing at this stage can overwork the gluten and make the loaf dense. Make sure the mix-ins are well scattered for even flavor in every slice.

Fill the Pan & Add Toppings

Transfer the batter into the prepared loaf pan, using the spatula to scrape every bit from the bowl. Smooth the top so it bakes evenly.

Sprinkle extra chocolate chips over the surface for a more decorative and chocolatey finish. Gently tap the pan on the counter to release any large air bubbles.

Bake Until Just Set

Place the loaf pan in the preheated oven on the center rack. Bake for 45 to 55 minutes, checking near the end.

Insert a toothpick into the center; it should come out with a few moist crumbs but no wet batter.

If needed, bake a few minutes longer, watching carefully to avoid overbaking.

Cool in the Pan Briefly

Remove the pan from the oven and place it on a wire rack. Let the banana bread cool in the pan for about 10 minutes.

This brief resting helps the structure set and makes it easier to remove without breaking. Don’t slice yet, as it will be too soft and may crumble.

Finish Cooling & Slice

Carefully lift the loaf from the pan using the parchment overhang or gently turn it out onto the wire rack. Let it cool for at least another 5 minutes, preferably longer, before slicing.

Use a serrated knife for clean slices. Serve warm or at room temperature, and store leftovers tightly wrapped.

Ingredient Swaps

• Make it dairy-free: use coconut or almond yogurt, plant milk, and dairy-free chocolate chips; choose a vegan protein powder.
• Make it egg-free: replace each egg with a flax egg (1 Tbsp ground flax + 3 Tbsp water, rested 5 minutes).
• Lower sugar: halve the honey/maple and add 1–2 Tbsp extra milk if batter seems thick; use very ripe bananas and stevia-sweetened chips.
• Flour swaps: use white whole wheat or spelt flour 1:1; for gluten-free, use a 1:1 gluten-free baking blend plus a bit more milk if needed.
• Fat options: swap coconut oil/butter with neutral oil (canola, sunflower) or light olive oil in the same amount.

You Must Know

– Make-Ahead • For the best slices and storage: Let the loaf cool until barely warm (at least 45–60 minutes total), then wrap tightly and chill 2–4 hours or overnight.

Fully cooled, slightly chilled bread slices cleaner, keeps moist for 3–5 days, and rewarms in 10–15 seconds per slice in the microwave.

Serving Tips

• Serve warm slices with a dollop of Greek yogurt and fresh berries.
• Drizzle with warm peanut or almond butter for extra protein and richness.
• Top with sliced banana and a light sprinkle of sea salt flakes.
• Pair with a cold glass of milk or a hot coffee/latte.
• Cut into cubes, chill, and serve as bite-size snack cake pieces.

Storage & Make-Ahead

This banana bread keeps in the fridge, tightly wrapped or in an airtight container, for up to 5 days.

It’s great for making ahead: slice once cooled, then refrigerate or freeze.

For freezing, wrap slices individually and store up to 2 months.

Thaw at room temperature or gently reheat.

Reheating

Reheat slices gently.

Microwave 10–20 seconds wrapped in a damp paper towel, warm in a 300°F (150°C) oven for 8–10 minutes, or toast on a covered skillet over low heat.

Banana Bread in Pop Culture

Once you’ve warmed a slice and the chocolate chips turn glossy and soft again, it’s easy to see why banana bread keeps showing up everywhere from cozy movie kitchens to viral TikTok videos.

I always notice it in shows where a character needs comforting—someone slices into a loaf, steam curls up, and suddenly the scene feels softer, safer.

During lockdown, my feed turned into a nonstop banana bread reel: celebrities sharing “secret” family recipes, fitness influencers flexing protein-packed versions, gamers nibbling slices between matches.

It wasn’t just food; it was a quiet way of saying, “I’m coping—are you?”

When you bake this chocolate protein version, you’re tapping into that same shared language: familiar, nostalgic, but with a little modern, health-conscious upgrade.

Frequently Asked Questions

How Much Protein per Slice and How Does It Compare to Regular Banana Bread?

Each slice packs roughly 8–12g protein, about double a typical banana bread’s 3–5g. When I eat it warm, chips melting, it feels like dessert, but I know I’m sneaking in a mini protein boost.

Can I Bake This Recipe as Muffins or Mini Loaves Instead?

Yes, you can bake this as muffins or mini loaves. I usually fill cups ¾ full, bake at 350°F for about 18–24 minutes, and watch for that fragrant, crackly top and clean toothpick.

Is This Banana Bread Suitable for Kids or Picky Eaters?

Yes, it’s usually a hit with kids and picky eaters. I’ve watched skeptical little faces soften after one bite—the chocolatey smell, moist crumb, and hidden protein make it feel like dessert, not “healthy” food.

Can I Make This Recipe Gluten-Free Without Affecting Texture Too Much?

Yes, you can. I swap the flour for a 1:1 gluten-free blend, then add an extra tablespoon of milk. The loaf stays tender, slightly fudgy, and my gluten-eating friends never notice the difference.

What’s the Best Way to Calculate Macros for This Banana Bread?

I’d enter every ingredient into a tracker like MyFitnessPal, set servings to 10 slices, then let it crunch calories, protein, carbs, fat. I tweak ingredients, recalc, and compare slices like little data-filled treats.
