Ingredients

Scale
  • 1 ½ cups fresh rhubarb stalks, cut into ½-inch pieces
  • ½ cup (50g) whey isolate protein powder
  • 1 cup (120g) whole wheat flour
  • 1 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • 1 teaspoon cinnamon
  • ¼ teaspoon salt
  • ½ cup (120ml) unsweetened applesauce
  • ⅓ cup (80ml) honey or maple syrup
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ½ cup (120ml) milk, dairy or plant-based

Instructions

  1. Preheat your oven to 350°F (175°C). Line your muffin tin with paper liners or lightly grease with cooking spray.
  2. Wash and chop rhubarb into ½-inch pieces. Set aside.
  3. In a medium bowl, whisk together whole wheat flour, whey isolate, baking powder, baking soda, cinnamon, and salt until no clumps remain.
  4. In another bowl, whisk eggs, unsweetened applesauce, honey or maple syrup, vanilla extract, and milk until smooth.
  5. Pour wet ingredients into dry ingredients and gently fold with a spatula until just combined; batter will be thick and slightly lumpy.
  6. Carefully fold in chopped rhubarb stalks evenly without breaking them up.
  7. Spoon batter into muffin tin cups about ¾ full. Optionally sprinkle a pinch of cinnamon or coarse sugar on top.
  8. Bake for 18-22 minutes, checking doneness with a toothpick which should come out clean or with few crumbs.
  9. Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Do not overmix the batter to avoid tough muffins. Sift whey isolate with dry ingredients to prevent clumps. Chop rhubarb uniformly for even cooking. If rhubarb is very tart, soak in water with a pinch of sugar for 10 minutes before folding in. Muffins can be stored at room temperature for 2 days or frozen for up to 3 months.
