High Protein Banana Bread Recipe

Prep Time: 10 minutes
Cook Time: 45 minutes
Total Time: 55 minutes
Servings: 10 slices
Protein per slice: ~18–22 grams

Ingredients

• 3 medium ripe bananas, mashed
• 3 large eggs
• 1/2 cup plain Greek yogurt (2% or full-fat)
• 1/4 cup unsweetened almond milk
• 1/3 cup maple syrup or honey
• 1 tsp vanilla extract
• 1 1/2 cups oat flour
• 1/2 cup vanilla or unflavored protein powder (whey or plant-based)
• 1/4 cup almond flour (optional, for tenderness)
• 1 tsp baking soda
• 1/2 tsp baking powder
• 1/2 tsp cinnamon
• 1/4 tsp salt
• Optional: 1/3 cup chopped walnuts or dark chocolate chips

Instructions

1. Preheat oven to 350°F (175°C). Line a 9×5-inch loaf pan with parchment paper or lightly grease it with coconut oil.
2. Mash the bananas in a large bowl until smooth. These will provide natural sweetness and moisture to your high protein banana bread.
3. Mix the wet ingredients: Whisk in eggs, Greek yogurt, almond milk, maple syrup, and vanilla until fully combined.
4. Combine dry ingredients: In another bowl, stir together oat flour, protein powder, almond flour, baking soda, baking powder, cinnamon, and salt.
5. Stir everything together: Fold the dry mixture into the wet until just combined. Avoid overmixing to keep your high protein banana bread light and fluffy.
6. Add mix-ins (if using) and fold gently into the batter.
7. Transfer batter to the loaf pan and smooth the top.
8. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out mostly clean.
9. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Tips & Substitutions

• Choosing the Right Protein Powder: If you’re after a softer, more cake-like texture, go with whey protein. Plant-based powders tend to make the loaf denser, so you may need to adjust the liquid slightly.
• Flour Alternatives: Want to switch things up? Whole wheat pastry flour or spelt flour both work beautifully in place of oat flour and add a slightly nuttier flavor.
• Sweetener Options: Looking to cut back on sugar? You can swap the maple syrup for mashed dates or use a sugar-free syrup without affecting the structure of the bread.
• Moisture Boost: If your protein powder tends to be dry or grainy, add a tablespoon of olive oil or coconut oil to the batter for a softer, more tender crumb.

Meal Prep & Storage Tips

One of the best things about this high protein banana bread is how well it holds up for meal prep. Whether you’re planning weekday breakfasts or stocking the freezer, here’s how to keep it fresh and tasty.

How to Store It in the Fridge

After baking, let your banana bread cool completely. This helps prevent sogginess from trapped steam. Slice the loaf and store it in an airtight container or wrap individual slices in parchment paper. It will stay fresh in the fridge for up to 5–6 days. If it firms up in the cold, just microwave a slice for 10–15 seconds to bring back that just-baked softness.

Freezing for Later

To freeze, wrap each slice tightly in plastic wrap or foil, then place them in a freezer-safe bag or container. Your banana bread will stay good for up to 3 months. When you’re ready to enjoy, just thaw at room temperature or pop a slice in the microwave for 20–30 seconds.

Extra Meal Prep Tips

• Double Up: Make two loaves, one for now, one for later.
• Pre-Slice for Convenience: Cut the loaf into 10 portions before storing to save time.
• Skip Fresh Fruit Mix-Ins: If you’re freezing, avoid juicy additions like fresh berries, which can turn soggy after thawing.

For best results, use BPA-free glass containers or reusable silicone bags to maintain freshness and avoid freezer burn. safe from freezer burn

Nutrition & Health Benefits

This banana bread isn’t just a sweet treat—it’s a smart way to fuel your body. With a combination of protein, fiber, complex carbs, and healthy fats, each slice pulls its weight as a satisfying snack or light meal.

A Protein-Powered Slice

Every piece packs 18 to 22 grams of protein, thanks to a mix of Greek yogurt, protein powder, and eggs. Whey isolate delivers fast-absorbing amino acids, ideal for post-workout recovery, while Greek yogurt brings casein for slow, steady release. Eggs round it out with a full profile of essential amino acids and added nutrients like choline.

These are all considered complete proteins, meaning they contain all nine essential amino acids (Healthline).

If you’re using a plant-based protein blend (like pea or hemp), you’ll still get great results—just opt for clean formulas without gums or artificial sweeteners.

Smart Carbs for Lasting Energy

This banana bread skips the white flour and refined sugar in favor of more balanced carbs:

• Oat flour provides beta-glucan fiber, known to support heart health and blood sugar balance. According to USDA data, oats are also a source of iron, magnesium, and B vitamins (USDA source)
• Bananas add natural sweetness plus potassium, vitamin B6, and a little prebiotic fiber.

Together, they give you the kind of energy that lasts without the crash.

Healthy Fats That Work for You

Ingredients like almond flour and eggs supply healthy fats that help with hormone balance, brain function, and satiety. You’ll also get a boost of vitamin E, omega-3s (if you use pastured eggs), and other important micronutrients.

Flexible for Many Diets

This recipe works well for a variety of eating styles:

• Gluten-free: Use certified gluten-free oats and you’re good to go.
• Dairy-free: Swap in coconut yogurt and plant-based protein.
• Low-sugar: Use a sugar-free syrup or reduce the sweetener if needed.

3. Eggs

Eggs are a complete protein, meaning they contain all nine essential amino acids. They also help bind the ingredients and add healthy fats that support nutrient absorption.

4. Ripe Bananas

Bananas offer natural sweetness, moisture, and a dose of potassium and vitamin B6. The riper they are, the less added sweetener you need in your protein banana bread.
