This easy baked oatmeal takes just 10 minutes to prep and 30 minutes to bake. It’s a cozy, healthy breakfast I turn to when I want something warm, filling, and made from scratch. The bananas and agave naturally sweeten it, and it’s perfect for meal prep too.

Ingredients for Easy Baked Oatmeal
- Whole wheat rolled oats - Use thick, old-fashioned oats for the best texture.
- Cinnamon - Adds warmth and pairs so well with banana.
- Baking powder - Helps the oats rise slightly and bake evenly.
- Plant-based milk - I used almond milk, but any milk works.
- Agave syrup - Lightly sweetens without refined sugar.
- Ground flaxseed - Adds fiber and helps bind everything.
- Vanilla extract - Adds a cozy, sweet aroma.
- Mashed bananas - Ripe bananas work best here.
- Nuts of choice - Pecans or walnuts are my favorite. Save a few for the topping.
- Toppings (optional) - Fresh berries, raisins, almond flakes, or yogurt.

How To Make Easy Baked Oatmeal
- Preheat oven: Set oven to 375°F (190°C).
- Mix dry ingredients: In an 8x8-inch baking dish, stir together oats, cinnamon, baking powder, and salt.
- Mix wet ingredients: In a separate bowl, mash bananas and mix in milk, agave, flaxseed, olive oil, and vanilla. Let sit for 5 minutes to thicken.
- Combine: Pour the wet mixture into the dry and mix until combined. Stir in chopped nuts.
- Bake: Clean the dish edges for a tidy look. Bake for 30 minutes or until golden on top and set in the center.
Can I make this without banana?
Yes, try applesauce or pumpkin puree instead.
Tips
- Use super ripe bananas – The spottier, the sweeter—they’re your natural sweetener here.
- Don’t overbake – Check the center at 30 minutes—it should be just set but not dry.
- Add berries – I love tossing in a handful of blueberries or raspberries for a juicy bite.
- Make it nut-free – Allergies? Just skip the nuts or sub in pumpkin or sunflower seeds.
- Maple syrup swap – Works just as well as agave and adds a rich, cozy sweetness.
- Choose your milk – Almond, oat, regular milk—whatever you’ve got works great.
- Want a treat? Add chocolate chips. It turns this into a fun snack!
- Serve it with yogurt – A spoonful on top makes it creamy and adds protein.
- Warm or cold – I honestly enjoy it both ways—great straight from the fridge or warmed up.
What To Serve With Easy Baked Oatmeal
I love serving this with something fresh and creamy:
- Maple syrup: A little extra drizzle on top.
- Greek yogurt: Adds protein and tang.
- Fresh fruit: Strawberries, blueberries, or sliced apples.
- Nut butter drizzle: Peanut or almond butter is delish.
Feeding a crowd? Double the recipe and bake it in a 9x13 pan.
