High Protein Banana Bread Recipe (15g Protein Per Slice, Moist & Healthy)

High protein banana bread delivers classic moist flavor with a nutritious boost of 12 grams of protein per slice. This easy recipe uses simple ingredients like protein powder and Greek yogurt for better texture and satisfaction.​

Why Choose High Protein Banana Bread

This recipe transforms traditional banana bread into a filling snack or breakfast option. Ripe bananas provide natural sweetness while Greek yogurt and protein powder add moisture and protein without compromising taste.​

Each slice offers sustained energy from balanced macros, making it ideal for busy mornings or post-workout fuel. Whole grains and low sugar keep it healthier than standard versions.​

Ingredients

Gather these pantry staples for one 9×5-inch loaf yielding 12 slices. Measurements appear in US customary units with metric in parentheses.

• 1 cup (80g) old-fashioned rolled oats
• 1/2 cup (60g) white whole wheat flour
• 1/2 cup (50g) vanilla protein powder (whey or plant-based)
• 1 teaspoon baking soda
• 1 1/2 teaspoons baking powder
• 1 teaspoon kosher salt
• 1 teaspoon ground cinnamon
• 3 large ripe bananas, mashed (about 1 1/2 cups or 360g)
• 1 large egg
• 1 cup (240g) plain Greek yogurt
• 1 teaspoon vanilla extract
• 2 tablespoons maple syrup (or honey)

Optional add-ins: 1/2 cup chocolate chips, chopped walnuts, or pecans.​

Step-by-Step Instructions

Follow these numbered steps for foolproof results. Preheat oven to 350°F (175°C) and grease a 9×5-inch loaf pan with parchment lining the bottom.

1. Blend oats in a food processor until flour-like, about 1 minute. Transfer to a large mixing bowl.​
2. Add protein powder, flour, baking soda, baking powder, salt, and cinnamon to the oat flour. Whisk to combine dry ingredients.​
3. In a separate bowl, mash bananas until smooth. Mix in egg, Greek yogurt, vanilla, and maple syrup until fully blended.​
4. Gently fold wet ingredients into dry until just combined – no overmixing to keep it tender. Stir in optional add-ins.​
5. Pour batter into prepared pan. Bake 35 to 45 minutes, tenting with foil after 25 minutes if browning too fast.​
6. Test doneness with a toothpick in the center – it should come out clean. Cool in pan 10 minutes, then transfer to a wire rack.​

Total time: 15 minutes prep, 40 minutes bake, 1 hour cool.

• Gluten-Free: Swap wheat flour for 1:1 gluten-free blend; ensure certified oats.
• No Yogurt: Replace with additional mashed banana or applesauce for moisture.
• Protein Powder: Unflavored works; adjust sweetener if needed. Avoid coconut flour as it dries out.​
• Sweetener: Honey, agave, or date syrup in equal amounts.

Variations and Add-Ins

Experiment for new flavors while maintaining nutrition.

• Chocolate Chip: Fold in 1/2 cup dark chocolate chips for indulgence.
• Nutty: Add 1/2 cup walnuts or pecans for crunch and healthy fats.
• Muffins: Divide into 12 muffin cups, bake 20 to 25 minutes.​
• Spice Boost: Double cinnamon or add pumpkin pie spice.

These keep protein high and texture moist.​

Storage and Serving Tips

Proper storage preserves freshness and flavor.

• Room temperature: Airtight container up to 3 days.
