Ingredients Equipment Method Notes

Ingredients
  

  • 3 medium very ripe bananas, mashed smooth about 1.25 cups
  • 1.5 cups old-fashioned rolled oats partially blended
  • 1/2 cup whole wheat flour or all-purpose flour
  • 2 large eggs
  • 1/3 cup plain Greek yogurt or unsweetened applesauce
  • 3 tbsp honey or pure maple syrup omit for babies under 12 months
  • 2 tbsp melted coconut oil or neutral oil
  • 1 tsp vanilla extract
  • 1.5 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp ground cinnamon
  • 1/4 tsp fine salt
  • 1/3 cup chocolate chips, chopped walnuts, or blueberries optional mix-ins

Equipment

  • Standard 12-Cup Muffin Tin
  • Blender or Food Processor for Oats
  • Large mixing bowl
  • Fork for Mashing Banana
  • Rubber Spatula

Method
 

  1. Preheat oven to 350°F. Line a 12-cup muffin tin with liners or grease thoroughly.
  2. Pulse rolled oats in a blender 8 to 10 times until coarsely ground with some oat pieces remaining. Set aside.
  3. Mash bananas in a large bowl until smooth. Add eggs, Greek yogurt, honey, oil, and vanilla. Whisk until combined.
  4. Add blended oats, flour, baking powder, baking soda, cinnamon, and salt. Stir with a spatula until just combined. Do not overmix. Fold in optional mix-ins with two or three strokes.
  5. Divide batter evenly among muffin cups, filling each about three-quarters full.
  6. Bake at 350°F for 18 to 22 minutes until tops are golden and a toothpick inserted into a center muffin comes out clean or with moist crumbs. Cool in tin 5 minutes then transfer to a wire rack.

Notes

  • Use bananas with heavily brown or black peels for the best sweetness and moisture - yellow bananas produce a noticeably blander muffin.
  • Partially blend the oats before mixing - this gives a more tender crumb without losing the oat texture entirely.
  • Do not overmix after adding dry ingredients - stir only until no dry streaks remain to avoid dense tough muffins.
  • Omit honey for babies under 12 months and replace with additional mashed banana or applesauce.
  • Freeze individually wrapped muffins for up to 3 months - microwave from frozen 30 to 40 seconds to thaw.
