The full recipe details are in the recipe card below. Here’s an overview of the ingredients and the method so you know what to expect before you bake.

What protein powder works best for banana bread

This recipe has been tested with plant-based pea protein powder and yields reliable results with that type. Collagen powder can be added as an optional scoop for extra protein without changing texture, but do not substitute collagen for the measured protein powder in the recipe. Unflavored or mildly flavored plant-based protein powders work well; if your powder is not sweet, consider a small amount of sweetener to balance the flavor.

Ingredients

  • Super ripe bananas – the riper and spotty they are, the sweeter the loaf.
  • Almond flour – can substitute cashew flour 1:1; use tiger nut flour for a nut-free option.
  • Protein powder – plant-based pea protein recommended; see notes about substitutions.
  • Eggs – provide structure and moisture.
  • Coconut oil or avocado oil – melted; butter or vegan butter may be used instead.
  • Coconut sugar or monk fruit – optional, for extra sweetness if needed.
  • Cinnamon – adds warmth and complements the banana flavor.
  • Baking staples – vanilla extract, baking powder, and a pinch of sea salt.
  • Optional streusel topping – quick oats, chopped pecans or walnuts, cinnamon, coconut sugar, coconut oil.

Steps

  1. Preheat and prepare: Preheat the oven to 350°F (175°C). Line a loaf pan with parchment paper.
  2. Mash bananas: In a food processor or bowl, mash the bananas until smooth. Add the eggs and melted oil and mix until combined.
  3. Add dry ingredients: Stir in almond flour, protein powder, baking powder, cinnamon, vanilla, and salt. Mix until just combined—do not overmix.
  4. Top (optional): Pour the batter into the prepared pan. If using streusel, combine the streusel ingredients until crumbly and sprinkle evenly over the top of the batter.
  5. Bake: Bake for about 35–40 minutes, until the edges are golden and a toothpick inserted in the center comes out clean. The center should feel set to the touch.
  6. Cool and finish: Allow the loaf to cool completely before slicing to prevent crumbling. Add the optional glaze if desired.

FAQ’s & Tips for the Best Banana Bread

  • Use ripe bananas: Dark, spotty bananas are sweeter and give the best flavor.
  • Storage: Keep the loaf in an airtight container in the refrigerator for up to five days. Slices freeze well; thaw and reheat before serving.
  • About coconut flour: This recipe is not formulated for coconut flour; coconut flour is much more absorbent and will change the texture and liquid needs.
  • Serving size: The recipe yields about 10 slices; one slice is a typical serving.
  • Protein powder flavors: You can experiment with flavored protein powders—chocolate, chai, or salted caramel will change the final taste, so choose a powder you enjoy.
  • Without protein powder: If you prefer classic banana bread without protein powder, use a standard almond flour banana bread recipe formulated without added protein powder.

  • Chocolate chip: Fold chocolate chips into the batter or sprinkle them on top instead of streusel.
  • Peanut butter swirl: Swirl peanut or other nut butter into the top before baking.
  • Nutty loaf: Fold in or top with chopped walnuts or pecans.
  • Festive: Add sprinkles for a celebratory touch.
  • Snickers-style: Top with chopped peanuts, chopped dates, and chocolate chips for a candy-inspired loaf.

Ingredients

Banana bread

  • 1 3/4 cups almond flour
  • 1/2 cup plant-based pea protein powder (see notes)
  • 1 scoop collagen powder (optional — do not swap this for the measured protein powder)
  • 3 small/medium super ripe bananas (about 1 1/2 cups mashed)
  • 3 large eggs, room temperature
  • 1/4 cup coconut or avocado oil, melted (or butter)
  • 2 tsp baking powder
  • 1 tsp cinnamon
  • 1 1/4 tsp vanilla extract and a good pinch of sea salt

Streusel topping

  • 1/4 cup coconut oil, melted
  • 1/4 cup coconut sugar or monk fruit
  • 2 tsp cinnamon
  • 1/3 cup quick oats
  • 1/3 cup finely chopped pecans or walnuts

Optional glaze

  • 1/3 cup powdered monk fruit sweetener (or regular powdered sugar)
  • 1 tbsp milk of choice
  • 1/2 tsp vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Line a loaf pan with parchment paper.
  2. In a food processor or large bowl, mash the bananas until smooth. Add eggs and melted oil and mix until combined.
  3. Add almond flour, protein powder, baking powder, cinnamon, vanilla, and salt. Stir until just combined—avoid overmixing.
  4. Pour batter into the prepared pan. Make streusel by mixing topping ingredients until crumbly and sprinkle over the batter if using.
  5. Bake 35–40 minutes, until edges are golden and a toothpick in the center comes out clean. The center should feel set.
  6. Cool completely before slicing. Add glaze if desired. If you skip the streusel, lightly toast slices and serve with almond butter.
  7. Note: Opening the oven or jostling the pan can cause slight sinking in the center. The loaf will still taste great, especially with topping or glaze.
