Here is the TikTok famous 1-Pan Baked Oatmeal that’s ready in under 30 minutes. Only 7 ingredients and no added sugar! A scrumptious, hearty, hot oatmeal breakfast, brunch or snack topped and served any way you please.


  • 2 small-medium ripe bananas
  • 1.5 tablespoons chia seeds
  • 1.25 cups rolled oats
  • 1/2 teaspoon ground cinnamon
  • ¼ teaspoon fine sea salt
  • 1.25 cups non-dairy milk of choice
  • 1 teaspoon vanilla extract
  • 2 cups mixed berries for topping (fresh or frozen)

Serve With


  1. Preheat oven to 350ºF and butter or grease 8×8 baking dish (or similar size).
  2. Peel bananas and mash directly into greased baking dish.
  3. Sprinkle chia seeds, rolled oats, cinnamon and salt directly over mashed bananas.
  4. Pour milk over top of dry ingredients and add vanilla; use fork to mix the ingredients together a bit, making sure chia seeds and oats are evenly distributed (it’s okay if some banana stays on bottom of pan).
  5. Add mixed berries to top of oatmeal mixture.
  6. Bake for 25-30 minutes, until liquid has absorbed. 
  7. Serve with your favorite toppings.


NOTE – This style of oatmeal has a consistency similar to stovetop oatmeal. It is much different than my baked oatmeal recipes that rise when baking and set. This is meant to be served as a bowl of oatmeal and does not work as squares.
