Ingredient Secrets for the Softest Texture

Ripe Bananas

Use deeply spotted bananas — they provide sweetness and moisture.

Peanut Butter

Natural peanut butter works best. Stir well before measuring.

Protein Powder

Use a quality chocolate whey or plant-based powder. If your batter feels thick, add a splash of milk.

Oat Flour

Blend rolled oats into fine flour if needed.

Tools You’ll Need

  • 9×5 inch loaf pan
  • Mixing bowls
  • Whisk
  • Spatula
  • Parchment paper

How to Make High Protein Peanut Butter Chocolate Banana Bread

Step 1: Preheat & Prepare

Preheat oven to 350°F (175°C).

Line loaf pan with parchment paper.

Step 2: Mash Bananas

Mash bananas until mostly smooth with small chunks remaining.

Step 3: Mix Wet Ingredients

In a large bowl, whisk together:

  • Mashed bananas
  • Greek yogurt
  • Peanut butter
  • Honey or maple syrup
  • Eggs
  • Vanilla

Mix until creamy and smooth.

Step 4: Combine Dry Ingredients

In another bowl, whisk:

  • Oat flour
  • Chocolate protein powder
  • Baking powder
  • Salt

Step 5: Combine Batter

Fold dry ingredients into wet ingredients.

Do not overmix.

Batter should be thick but spreadable.

If too thick, add 1–2 tablespoons milk.

Step 6: Add Chocolate Chips

Fold in chocolate chips.

Reserve a few for topping.

Step 7: Bake

Transfer batter into prepared pan.

Sprinkle remaining chocolate chips on top.

Bake for 40–50 minutes.

If top browns quickly, tent with foil.

Toothpick should come out clean or with moist crumbs.

Step 8: Cool

Cool in pan for 15 minutes.

Transfer to rack and cool completely before slicing.

This ensures soft interior texture.
