Chocolate Chip Protein Banana

There's something about the smell of banana bread baking that stops me mid-conversation. My kitchen fills with this warm, almost vanilla-like sweetness that makes everyone pause and ask what's happening in the oven. This version came about when I wanted that comfort without the guilt—a loaf that felt indulgent but wasn't hiding anything sinister in the ingredient list. The protein powder was a happy accident; I had it on hand one morning and thought, why not? It turned out to transform the whole texture into something denser, more substantial, and honestly more satisfying than traditional banana bread.

I made this for a friend who was trying to eat better but kept sabotaging herself with store-bought muffins. When she bit into a slice and her eyes went wide, she literally said, 'This tastes like it's bad for me.' That moment right there—that's why I keep making it. She now texts me whenever she runs out, which tells me everything.

Ingredients

• Ripe bananas (3 large, mashed): The darker and softer, the better—they bring natural sweetness and moisture that keeps this loaf from drying out.
• Eggs (2 large): They bind everything together and add richness; room temperature ones mix more smoothly than cold ones straight from the fridge.
• Maple syrup or honey (80 ml / ⅓ cup): Either works beautifully; maple syrup gives a deeper flavor, while honey brings a lighter floral note.
• Melted coconut oil (60 ml / ¼ cup): Keeps the crumb moist and tender; olive oil works too if you want a slightly less tropical taste.
• Vanilla extract (1 tsp): Use real vanilla if you can—it makes a noticeable difference in the final flavor.
• Whole wheat flour (180 g / 1½ cups): Adds earthiness and structure; don't skip this for all-purpose flour unless you want a completely different texture.
• Vanilla or unflavored protein powder (30 g / ⅓ cup): This changes the game—it adds protein without the cake-like heaviness, and vanilla powder blends seamlessly into the batter.
• Baking soda (1 tsp): Works with the acidic bananas to create lift and a tender crumb.
• Baking powder (½ tsp): Extra leavening that ensures the bread rises evenly without sinking in the middle.
• Ground cinnamon (½ tsp): Warm spice that complements chocolate and banana in ways that feel almost magical.
• Fine sea salt (¼ tsp): Amplifies the sweetness and makes the chocolate taste more like chocolate.
• Dark chocolate chips, 70% cocoa (80 g / ½ cup): No added sugar versions exist and they're absolutely worth seeking out; they taste sophisticated, not like punishment.
• Chopped walnuts or pecans (30 g / ¼ cup, optional): Add textural contrast and richness, but honestly the bread is perfect without them if you prefer.

Instructions

Prepare your stage:

Preheat your oven to 175°C (350°F) and grease a 23 x 13 cm loaf pan, then line it with parchment paper—this little step saves you from frustration when it's time to remove the finished loaf. The parchment should stick up slightly on the sides so you can grab it as a handle.

Merge the wet ingredients:

Mash your bananas in a large bowl until mostly smooth (a few tiny lumps are fine and add texture). Whisk in the eggs, maple syrup, melted coconut oil, and vanilla extract until everything looks pale and cohesive—this takes about a minute of whisking.

Combine the dry goods:

In a separate bowl, whisk together the whole wheat flour, protein powder, baking soda, baking powder, cinnamon, and salt. This step matters more than it sounds because it distributes the leavening agents evenly throughout.

Bring them together gently:

Pour the dry mixture into the wet bowl and stir with a spatula or wooden spoon just until the flour disappears—overmixing develops gluten and makes the bread tough and dense. Stop when you still see a tiny swirl of flour; it'll come together in the oven.

Fold in the chocolate and nuts:

Gently fold in the dark chocolate chips and nuts if you're using them, making sure they're distributed so every slice gets chocolate. Don't pulverize them in the mixing.

Get it in the oven:

Pour the batter into your prepared pan and smooth the top gently with a spatula. Scatter a few extra chocolate chips across the surface if you want that bakery-style look.

Bake with patience:

Bake for 50 to 55 minutes until a toothpick inserted in the center comes out clean (a few melted chocolate streaks clinging to the pick are a good sign, not a problem). Every oven is slightly different, so start checking at 48 minutes.

Cool thoughtfully:

Leave it in the pan for 10 minutes so it sets enough to move without falling apart, then turn it out onto a wire rack to cool completely. Don't slice it warm or it'll fall apart; wait until it's cool enough to handle comfortably.

Pin it

One morning my partner cut into a cool loaf while I was still half-asleep, and the sound of that knife gliding through the crumb was so clean and satisfying that I actually stopped and listened. We ate the first slice standing at the counter with black coffee, not talking much, just present with how good something simple could be. That's when I knew this recipe had become something beyond just food—it was a small ritual we looked forward to.

Storage and Keeping

This loaf keeps beautifully for about three days wrapped in parchment paper and stored in an airtight container at room temperature, though it never lasts that long in our house. If you want it to last longer, slice it, layer the slices with parchment between each one, and freeze for up to three months—toasting a slice from frozen tastes almost as good as fresh.

Flavor Swaps and Customizations

This bread is a forgiving foundation for your preferences. Maple syrup brings warmth and depth, but honey creates a lighter, almost delicate sweetness—try date syrup if you want something with caramel notes and more minerals. Vanilla protein powder is my default, but unflavored works just as well and lets the banana and chocolate shine without competition. If you want to push it further into breakfast territory, add a tablespoon of chia seeds or ground flaxseed to boost fiber and add a subtle nuttiness.

Pairing and Serving

This loaf stands alone beautifully, but a cup of black coffee makes it feel like a deliberate moment rather than just grabbing food. Cold almond milk is equally good, especially if you're having it post-workout when your body is asking for something both nourishing and comforting. For a small brunch gathering, I slice it and serve it slightly warm with a dollop of Greek yogurt on the side—people think you spent hours when really you just mixed two bowls.

• Toasting a slice from the day before brings back the warm aroma and softens the crumb beautifully.
• If you need it to feel fancier, dust a slice with a tiny pinch of sea salt flakes before eating—it elevates the chocolate without making it obvious.
• Leftover slices freeze individually wrapped, so you can grab one anytime the craving hits without thawing the whole loaf.

Pin it

This banana bread taught me that healthy eating doesn't have to taste like deprivation—it just has to taste like it was made with care. Make it once and it'll become the recipe you return to, the one you share without hesitation, the one that fills your kitchen with that smell people can't quite place but absolutely love.
