Ingredients
  

  • Oat flour (store-bought or homemade from rolled oats)
  • Protein powder (vanilla or unflavored; whey or plant-based)
  • Baking powder and baking soda
  • Cinnamon and a pinch of salt
  • Mashed ripe banana (or unsweetened applesauce)
  • Greek yogurt (or dairy-free yogurt)
  • Eggs (or flax eggs for vegan)
  • Milk of choice (dairy or unsweetened almond/oat milk)
  • Maple syrup or honey (or your preferred sweetener)
  • Vanilla extract
  • Coconut oil or light olive oil (melted)
  • Optional mix-ins: blueberries, mini chocolate chips, chopped walnuts/pecans, shredded coconut, or seeds

Method
 

  1. Prep the pan and oven: Heat oven to 350°F (175°C). Line a 12-cup muffin pan with liners or grease lightly.
  2. Whisk dry ingredients: In a large bowl, combine 1 3/4 cups oat flour, 1/2 cup protein powder, 1 1/2 teaspoons baking powder, 1/2 teaspoon baking soda, 1 teaspoon cinnamon, and 1/4 teaspoon salt.
  3. Mix wet ingredients: In a separate bowl, whisk 1 mashed ripe banana (about 1/2 cup), 1/2 cup Greek yogurt, 2 eggs, 1/3 cup milk, 1/4 cup maple syrup, 2 teaspoons vanilla, and 2 tablespoons melted coconut oil until smooth.
  4. Combine: Pour wet ingredients into dry. Stir gently until just combined. If the batter looks too thick, add 1–2 tablespoons milk. It should be thick but scoopable.
  5. Fold in extras: Add up to 3/4 cup mix-ins, like blueberries or mini chocolate chips. Don’t overmix.
  6. Fill the cups: Divide batter evenly among the 12 muffin cups. They should be about 3/4 full.
  7. Bake: Bake 15–19 minutes, or until a toothpick comes out mostly clean with a few moist crumbs.
  8. Cool: Let muffins rest in the pan for 5 minutes, then transfer to a rack. Cooling helps set the texture.
  9. Taste and tweak: Try one warm. If you like sweeter muffins, drizzle with a little honey or add a few extra chocolate chips next time.
