  • 2 ripe bananas, mashed (approx 1/3 cup)
  • 2 eggs, or flax or chia egg
  • 1/4 cup butter or coconut oil, melted
  • 1 + 1/2 cups milk of choice
  • 1/2 cup maple syrup
  • 4 cups quick oats
  • 2 tsp cinnamon
  • 1 + 1/2 tsp salt
  • 2 tsp baking powder
  • 2 cups blueberries, fresh or frozen
  • Optional toppings: Greek yogurt, regular yogurt, coconut yogurt, fresh fruit, nuts or seeds like crushed almonds, pecans, or pumpkin seeds.


  1. Preheat oven to 350 degrees F.
  2. Line an 11 x 11 baking dish with parchment paper. Alternatively, grease it with butter or coconut oil.
  3. Combine the wet ingredients in a large bowl (mashed banana, eggs, butter, milk, maple syrup)
  4. In a medium bowl, whisk together the dry ingredients (quick oats, cinnamon, salt, baking powder)
  5. Add dry ingredients to wet ingredients and gently mix to combine with a fork. Fold in the blueberries.
  6. Pour oatmeal batter into prepared baking dish and bake in the oven for 30-35 minutes.  To check if your baked oatmeal is ready, poke the center with a cake tester or toothpick. If it comes out clean it’s done!
