for the oatmeal:

  • 4 small/medium bananas 1 cup mashed bananas
  • 2 large eggs
  • 1 cup milk 240ml
  • 2 teaspoons vanilla extract
  • 1 teaspoon cinnamon
  • 1 tablespoon lemon juice
  • 1/4 cup maple syrup
  • 2 tablespoons coconut oil melted or soft, or butter
  • 3/4 teaspoon baking powder can be omitted
  • pinch of salt
  • 2 cups rolled oats 7 oz/200g
  • 1 tablespoon coconut oil for greasing the baking dish, or butter


  • 1 cup blueberries 100g
  • 1/4 cup walnuts


  • Preheat the oven to 375°F/190°C/Gas Mark 5, no fan (if you have a convection oven, reduce the temperature by about 20° or follow the manufacturer's instructions).
  • Prepare a 9-inch (23 cm) round baking dish (I used a pie dish) or a 8×8-inch square (20x20cm) baking dish (or similar) and grease it with 1 teaspoon of coconut oil.
  • Mash the bananas with a fork.
  • Add all the ingredients for the oatmeal except the oats into a medium bowl and whisk until very well combined. Next, whisk in the oats.
  • Pour the oatmeal batter into the baking dish.
  • Top with walnuts and blueberries.
  • Bake for about 30 minutes or until the oatmeal is set but still creamy (not dry). The baking time may vary depending on the oven.
  • Leave to set and cool for about 5 minutes, then serve (I like it most with plain yogurt and maple syrup).
  • Enjoy!



  • This baked oatmeal recipe yields 5 servings, considering that you’ll serve it with additional yogurt and maple syrup. It can be easily doubled – double the ingredients and bake it in a 9×13-inch (23x33cm) baking dish. The baking time stays the same (if the oatmeal is still runny in the center, bake it for 5 minutes longer).
  • Calories = 1 serving (1/5 of the recipe). This is only an estimate!
