Ingredients
  

  • Let’s keep this simple flexible, and totally pantry-friendly. This protein banana bread relies on classic banana bread staples plus a few smart add-ins that boost protein without sacrificing that moist, tender texture you want.

Core Ingredients

  • 3 very ripe bananas
  • The riper the better—deep brown spots = more natural sweetness and better moisture.
  • 2 large eggs
  • Helps bind the batter and supports a fluffy crumb.
  • 1/2 cup Greek yogurt
  • A key secret for moist high protein banana bread with a rich bakery-style feel.
  • 1/4 cup maple syrup or honey
  • Adjust slightly based on how sweet your bananas are.
  • 1 tsp vanilla extract
  • 1 1/2 cups oat flour
  • A great base for banana bread with protein powder—soft hearty, and naturally gluten-free if certified.
  • 1 scoop protein powder about 25–35g
  • Whey or plant-based both work with small tweaks see below.
  • 1 tsp baking soda
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1 –1 1/2 tsp cinnamon

Optional Add-Ins

  • Pick one or combine:
  • 1/3 cup dark chocolate chips
  • 1/3 cup chopped walnuts or pecans
  • 1/2 cup blueberries
  • 1 –2 tbsp chia or ground flax for extra fiber

Protein Powder Tips That Really Matter

  • Not all protein behaves the same in baking so this is where you can set yourself up for success:
  • Whey protein
  • Usually gives the most classic banana bread texture.
  • Plant-based protein
  • Tends to absorb more moisture. If your batter looks thick add:
  • 1 –3 tbsp milk any kind
  • or a little extra yogurt

Easy Swaps if You Need Them

  • These keep the recipe meal prep friendly and adaptable:
  • No Greek yogurt?
  • Use cottage cheese skyr, or plain yogurt.
  • Want lower sugar?
  • Reduce the sweetener to 2–3 tbsp especially with very ripe bananas.
  • Prefer a nuttier flavor?
  • Replace 1–2 tbsp of flour with almond flour.
  • Dairy-free option
  • Use plant-based yogurt and your favorite non-dairy milk.
  • Egg-free option
  • Swap in 2 flax eggs 2 tbsp ground flax + 5 tbsp water.
  • Expect a slightly denser more tender loaf.

Instructions
 

  • This protein banana bread comes together quickly, and the method is very forgiving—as long as you treat the batter gently. Think cozy classic banana bread vibes, just with a protein-powered upgrade.

Quick Setup

  • Oven: Preheat to 350°F (175°C).
  • Pan: Grease or line a 9x5-inch loaf pan with parchment for easy lift-out.
  • Bananas: The riper, the better. If they smell sweet, you’re in business.

Step-by-Step

  • Mash the bananas
  • In a large bowl, mash 3 ripe bananas until mostly smooth. A few small lumps are perfect—they add texture and extra banana flavor.
  • Whisk the wet ingredients
  • Add:
  • 2 eggs
  • 1/2 cup Greek yogurt
  • 1/4 cup maple syrup or honey
  • 1 tsp vanilla
  • Whisk until silky and well combined.
  • Add the dry ingredients
  • Sprinkle in:
  • 1 1/2 cups oat flour
  • 1 scoop protein powder
  • 1 tsp baking soda
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1–1 1/2 tsp cinnamon
  • Fold gently
  • Use a spatula to fold until just combined.
  • This step is key for moist high protein banana bread—overmixing can make it dense.
  • Stir in add-ins (optional)
  • Fold in:
  • chocolate chips
  • walnuts
  • blueberries
  • chia or flax
  • Keep it light and minimal—your loaf will thank you.
  • Bake
  • Pour the batter into the pan and smooth the top.
  • Bake for 45–60 minutes, depending on your oven and protein powder.
  • Check for doneness
  • Your banana bread with protein powder is ready when:
  • the top looks set and lightly golden
  • a toothpick comes out with a few moist crumbs
  • the center springs back gently when pressed
  • Cool before slicing
  • Let the loaf cool in the pan for 10–15 minutes, then transfer to a rack.
  • Wait another 20–30 minutes before slicing for the cleanest, tender crumb.

Tiny Fixes That Make a Big Difference

  • If your batter looks too thick (common with plant protein):
  • Add 1–3 tbsp milk or a spoonful more yogurt.
  • If you want a taller, bakery-style loaf:
  • Use the 9x5 pan, and avoid overloading with heavy mix-ins.
