High Protein Banana Bread Without Added Sugar
This small-batch banana loaf uses Greek yogurt and very ripe bananas to add protein and natural sweetness. It is made without table sugar or honey and is tuned for 1 to 2 servings with a soft tender crumb.
This loaf is sized for one or two people and uses simple pantry items and a single small pan so cleanup is minimal. Mix the batter in one bowl and bake while you wash the bowl.
The texture is soft and tender. Use the suggested swaps to make the crumb even gentler for chewing or easier on digestion if needed.
Ingredients You’ll Need
- 1 medium very ripe banana, mashed (about 100 to 120 g)
- 1/2 cup plain Greek yogurt (120 g)
- 1/4 cup protein powder (25 to 30 g), whey or plant
Full recipe also uses 1 large egg, 1/2 cup flour, 1 tablespoon oil, baking powder, baking soda, cinnamon, vanilla, and optional finely chopped walnuts or ground flaxseed. Bake in a 5 x 3 inch mini loaf pan or a small ramekin.
Step-by-Step Recipe
- Preheat the oven to 350 F (175 C) and lightly grease a 5 x 3 inch mini loaf pan or line it with parchment.
- In a medium bowl mash the banana then whisk in the egg, Greek yogurt, oil, and vanilla. Sprinkle in the protein powder, flour, baking powder, baking soda, salt, and cinnamon and fold gently until just combined.
- Fold in optional finely chopped walnuts or ground flaxseed, spoon batter into the pan and bake 28 to 34 minutes until a toothpick comes out mostly clean. Cool 10 minutes in the pan then transfer to a rack and cool another 10 minutes before serving.
Tips and Easy Variations
Texture swaps
- For extra soft texture add 1 tablespoon more Greek yogurt and reduce oil to 1 teaspoon.
- Keep mix-ins small so the crumb stays tender and easy to chew.
- Serve warm with a spoonful of extra yogurt for added protein and softness.
Flour and digestion
- Use oat flour or whole wheat pastry flour for a lighter, gentler loaf.
- If digestion is a concern keep mix-ins finely ground or omit them.
- Adjust yogurt up slightly to make the bread moister and easier on digestion.
Protein alternatives
- No protein powder use 3/4 cup total flour and 3/4 cup Greek yogurt to keep protein from yogurt.
- To boost protein slightly add a tablespoon of powdered milk or a bit more protein powder and a touch more flour if batter seems thin.
- Top a slice with nut butter or extra yogurt for more protein at serving time.
Quick tips
- Omit the pinch of salt if advised by your doctor since banana and vanilla give plenty of flavor.
- Chop nuts very finely or leave them out for the softest crumb.
- Use a thicker plant yogurt if you need a dairy free version for similar texture.
