Prep Time10 minutes
Cook Time35 minutes
Total Time45 minutes
Yield: 9 servings

Ingredients

  • 2 cups old fashioned rolled oats
  • ½ cup walnuts, chopped (see notes)
  • 1 teaspoon baking powder
  • 1 ½ teaspoons ground cinnamon
  • ½ teaspoon kosher salt
  • 2 medium ripe bananas
  • 1 large egg
  • 1 ½ cups milk of choice
  • ½ cup unsweetened applesauce
  • ⅓ cup maple syrup
  • 2 tablespoons unsalted butter, melted
  • 1 teaspoon vanilla

Instructions

  • Preheat the oven to 375.
  • Mix the first 5 ingredients (oats through salt) together in a large bowl.
  • In a separate medium bowl, mash the banana with a fork. Then beat in the egg and add remaining ingredients (through vanilla). Mix well.
  • Add the wet ingredients to the dry ingredients and stir to combine.
  • Pour the mixture into a greased 8x8 pan. It will be very liquidy and very full. It’s OK.
  • Bake at 375 for about 35 minutes, until set and cooked through.
  • Let sit for at least 5-10 minutes before slicing and serving so it sets up all the way.
  • Enjoy warm or cold. See notes below for storing tips.

Notes

This is delicious warm and also great served cold from the fridge.
Walnuts: These make it feel like banana bread to me, but I've also left them out before and that was fine (in case you need this to be nut-free).
Storage: This baked oatmeal will keep covered, on the counter, for up to 2 days. After that, I recommend you move it to the fridge, where it will keep for another 2-3 days. You can also freeze the leftovers. Cut your baked oatmeal, once cooled, into squares. Place them in a freezer-safe ziptop bag (that’s labeled!) and freeze for up to 6 months.
For a fun treat, you can also add ½ cup of chocolate chips to the batter.
