Ingredients

Scale
  • 2 medium ripe bananas, mashed
  • 1/2 cup peanut butter (creamy or crunchy)
  • 1 cup protein powder (neutral or vanilla-flavored whey or plant-based)
  • 3/4 cup whole wheat flour (can substitute almond flour for gluten-free)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 cup plain Greek yogurt (or dairy-free coconut yogurt)
  • 2 tablespoons honey or maple syrup (optional)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon cinnamon (optional)
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your muffin tin or line with silicone or parchment liners.
  2. Mash the bananas in a large bowl until mostly smooth with some small chunks remaining.
  3. Add peanut butter, Greek yogurt, eggs, honey or maple syrup, and vanilla extract to the mashed bananas. Whisk until combined and creamy.
  4. In a separate bowl, sift together protein powder, whole wheat flour, baking powder, baking soda, cinnamon, and salt.
  5. Gradually fold the dry ingredients into the wet ingredients using a spatula until just combined. Avoid overmixing.
  6. Spoon the batter evenly into 12 muffin cups, filling each about 3/4 full.
  7. Bake for 18-22 minutes until muffins are golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs.
  8. Let muffins cool in the pan for 5 minutes before transferring to a wire rack. Serve warm or at room temperature.

Notes

Use ripe bananas with brown spots for best sweetness and moisture. Avoid overmixing the batter to keep muffins tender. If protein powder dries out the batter, add an extra tablespoon of yogurt. Tent muffins with foil if browning too fast. Batter can be prepared the night before and refrigerated. For vegan adaptation, replace eggs with flax eggs and use dairy-free yogurt and plant-based protein powder.
