🍌 Protein Banana Bread brings together the comfort of a classic banana loaf with the intention of a high‑protein snack, creating a bake that feels both indulgent and purposeful from the very first slice. The aroma of ripe bananas and warm oats rising in the oven sets the tone for something that feels homely yet quietly athletic, as if it belongs equally on a brunch table and in a post‑workout routine. Each slice reveals a soft, moist crumb that holds together beautifully, thanks to the combination of oat flour, eggs and whey protein. The peanut butter adds a subtle richness that lingers on the palate, giving the bread a satisfying depth without overwhelming the natural sweetness of the bananas. The loaf feels substantial in the hand, yet light enough to enjoy without heaviness, making it ideal for breakfast, a mid‑afternoon boost or a late‑night bite. The whey protein blends seamlessly into the batter, turning a familiar comfort food into a macro‑friendly option that supports your goals rather than derailing them.☕
🍞 As the bread bakes, the top turns a gentle golden colour, hinting at the tender interior that waits beneath. The oat flour brings a rustic, slightly nutty note that pairs beautifully with the banana and peanut butter, creating a flavour profile that feels warm and grounded. Each bite offers a balance of sweetness, softness and gentle chew, making the loaf feel satisfying without being dense. The recipe respects your time, coming together in just a few simple steps that require no special equipment or advanced skills. The batter mixes quickly, pours smoothly and bakes into a loaf that slices cleanly once cooled. Every slice carries a sense of intention, as if you have chosen something that honours both enjoyment and nourishment. The macros are thoughtfully balanced, offering around 11 grams of protein per serving, which makes the bread more than just a treat.🍂

📅 Nutrition Per Serving (entire recipe, 8 portions)
Approximate values per serving (one of eight slices):
Energy: 191 kcal
Protein: 11.1 g
Carbohydrates: 23.1 g
Fat: 7.5 g
Calculated from: 1½ cups oat flour, ½ cup whey protein powder, 1½ teaspoons baking powder, 1¼ cups mashed ripe banana (about 3 large bananas), 2 large eggs, ¼ cup peanut butter, no added sugar in the batter, optional protein spread for topping not included in the macros.
👨🍳 How to Make It (Step‑by‑step)
✔️ Prepare the loaf pan
Grease a loaf pan and line it with parchment paper to ensure the bread releases easily after baking.
💡 Make sure the parchment overhangs slightly at the sides so you can lift the loaf out cleanly once it has cooled.
✔️ Combine the dry ingredients
In a mixing bowl, add the oat flour, whey protein powder and baking powder, then whisk until evenly combined.
💡 Break up any lumps in the protein powder with the whisk to avoid pockets of dry powder in the finished loaf.
✔️ Mash the bananas
In a separate bowl, mash the ripe bananas until smooth and creamy, with no large chunks remaining.
💡 Use very ripe bananas with brown spots for maximum sweetness and better texture in the bread.
✔️ Add the eggs
Crack the eggs into the mashed bananas and whisk until the mixture looks uniform and slightly frothy.
💡 Room‑temperature eggs blend more easily and help the batter come together smoothly.
✔️ Incorporate the peanut butter
Add the peanut butter to the banana and egg mixture and stir until fully combined and silky.
💡 If the peanut butter is very thick, warm it slightly so it mixes more easily into the wet ingredients.
✔️ Combine wet and dry mixtures
Pour the banana, egg and peanut butter mixture into the bowl with the dry ingredients and whisk until smooth.
💡 Mix just until no dry streaks remain to avoid overworking the batter and making the loaf tough.
✔️ Adjust the batter consistency
Check the batter to ensure it is thick but pourable, with a smooth, even texture.
💡 If the batter feels extremely thick, you can add a tablespoon of water or milk, but only if absolutely necessary.
✔️ Fill the loaf pan
Pour the batter into the prepared loaf pan and spread it into an even layer, smoothing the top with a spatula.
💡 Tap the pan gently on the counter to release any trapped air bubbles and help the loaf bake evenly.
✔️ Bake the bread
Place the pan into a preheated oven at 350°F (180°C) and bake for 35–40 minutes until the top is set and lightly golden.
💡 Insert a toothpick into the centre; if it comes out mostly clean with a few moist crumbs, the bread is ready.
✔️ Cool and serve
Remove the loaf from the oven and allow it to cool in the pan before lifting it out and slicing.
💡 Let the bread cool completely for the cleanest slices and then add protein spread on top if you want an extra boost.
