  • cups rolled oats
  • 2 tablespoons all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 2 tablespoon chia seeds
  • 2 ripe bananas smashed
  • 2 eggs
  • ½ cup brown sugar
  • 4 tablespoons unsaled butter melted
  • cups oat or almond milk or milk of choice
  • ½ cup chopped walnuts
  1. Pre-heat the oven to 350°F. Grease a 9-inch by 13-inch baking pan with butter.
  2. Combine the rolled oats, flour, baking powder, salt, and cinnamon in a bowl.
  3. Smash the bananas with a fork in a separate bowl. Add the eggs and brown sugar and stir until smooth. Pour in the melted butter and milk and stir until combined. Then add the dry ingredients to the wet ingredients and fold in the walnuts. Pour the mixture into the prepared baking dish.
  4. Bake at 350°F for 30 to 35 minutes.

  5. Let cool for 20 minutes and then cut into 12 servings. Serve warm or at room temperature.
