Ingredients Equipment Method Notes

Ingredients
  

  • 2 large ripe bananas
  • 2 cups old-fashioned rolled oats
  • 1¾ cups milk of choice (e.g. almond milk)
  • 1 cup fresh or frozen blueberries
  • 1 large egg
  • ¼ cup pure maple syrup or honey
  • 1 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 1 tsp baking powder
  • ½ tsp fine sea salt
  • 1 pinch nutmeg

Equipment

  • large mixing bowl
  • whisk
  • spatula
  • 8x8 baking dish
  • measuring cups and spoons
  • oven

Method
 

  1. Preheat oven to 375°F (190°C) and grease an 8x8-inch baking dish well.
  2. In a large bowl, mash the bananas until almost smooth. A few small chunks are fine.
  3. Whisk in the egg, milk, maple syrup, and vanilla extract until well combined and slightly frothy.
  4. Add the oats, baking powder, cinnamon, salt, and nutmeg. Stir until just combined — do not overmix.
  5. Fold in the blueberries. If using frozen, do not thaw them first to avoid discoloring the batter.
  6. Pour mixture into greased baking dish and spread evenly. Optionally, sprinkle a few extra oats or berries on top.
  7. Bake for 35–40 minutes until golden brown and center is set. Let cool slightly before slicing and serving.

Notes

Let cool fully before storing. Keeps in fridge for up to 5 days or freezer for 3 months. Reheat individual slices in the microwave. For a vegan version, swap the egg for a flax egg and use plant-based milk. You can replace blueberries with chopped apples, raspberries, or dark chocolate chips. Add chopped nuts for crunch or a scoop of protein powder for extra nutrition.
