You Will Love Single Serve Baked Oatmeal

Whether or not you’ve tried one of my classic baked oatmeal recipes or the trendy TikTok baked oats I know you’re going to love the variety of single-serving baked oatmeal recipes I came up with as well (including this one)! Here’s why:

  • Easy to prep – it’s so simple to prep. Just mix all of the ingredients and bake!
  • Minimal clean up – yep, everything is mixed in one bowl and then baked in another… just two dishes to clean!
  • Single serving – don’t worry about having leftovers to pack up for the week… just make what you’re craving NOW!
  • Healthy and filling – this single serve baked oatmeal is packed with fiber. I also added protein powder to make it even more satisfying.

Baked oatmeal is so simple to make. Made with simple ingredients and mixed in just one bowl. Enjoy this healthy banana flavored single serve version!

Ingredients measured out to make banana walnut baked oatmeal.

Here’s What You Need

Baked oatmeal requires minimal ingredients, here’s the full list:

  • rolled oats – I recommend using rolled oats because they are less processed and give a good texture to the baked oatmeal.
  • dairy-free milk – I like to use unsweetened almond milk but any dairy-free milk will work and if you have cow’s milk on hand, that works too!
  • almond or peanut butter – you can use almond butter or peanut butter for this recipe. Look for a natural brand with one 1 or 2 ingredients: nuts and salt!
  • chia seeds – optional, but I like to add for extra fiber and healthy fats. Read all about the health benefits of chia seeds here.
  • baking powder – helps the baked oatmeal rise and lightens the texture of the baked oatmeal.
  • cinnamon – I’m a cinnamon lover so I add cinnamon to almost all of my baked oatmeal recipes.
  • maple syrup – add a hint of sweetness with maple syrup.
  • vanilla extract – just a touch of vanilla flavor.
  • sea salt – just a pinch to bring all of the flavors together.
  • banana – adds moisture, a subtle flavor and sweetness to this baked oatmeal. You’ll add mashed banana to the batter and then top with sliced bananas.
  • chopped walnuts – you can use any nut you’d like but I love walnuts with bananas!
  • vanilla protein powder – optional but I like to add it for a protein boost! I use Nuzest protein powder (use my code eatingbirdfood for 15% off)

What if I Need More Than 1 Serving?

You’re in luck! I created this Peanut Butter Banana Baked Oatmeal recipe that makes 6 servings. This recipe is great if you want to bake once and have it for breakfast all week! The recipe is super similar to the single serve version, just for a larger portion. I also have this Banana Baked Oatmeal Cups if you want a larger quantity in muffin form! These are really portable and perfect for kiddos.

If you're cooking for a crowd or want to meal prep a larger portion, make my Peanut Butter Banana Baked Oatmeal that makes 6 servings or my Banana Baked Oatmeal Cups for an oatmeal muffin!

Can I Make It Ahead of Time

This recipe is best enjoyed right after baking! It does take about 40 minutes to prepare, but much of that time is hands-off cooking time! Obviously not the best recipe for busy morning, but great for a relaxing weekend breakfast.

If you want to try prepping it in advance you can combine all the ingredients, place in a covered container and then transfer to the baking dish and bake the next morning. I haven’t fully tested this method, but it should work just fine.

How to Serve

I personally eat this baked oatmeal on it’s own, but you could absolutely pair with more options for a full breakfast spread. Here’s what I would serve with this recipe:

  • Fruit Salad with Mint – I love having something cool and refreshing with warmer breakfasts!
  • Hard Boiled Eggs – keep it simple with hard boiled eggs to get in more protein and healthy fats.
  • Healthy Frappuccino – treat yourself to this homemade coffee drink. It’s so delicious!

    I accidentally added a whole banana instead of 2 tbsp so i used two 10 oz ramekins, but it was so good! i also added choco chips instead of walnuts and use almond butter and it was so good!

    1. Ah amazing! I am so glad this recipe ended up working out great for you, Madison. Thanks so much for taking the time to share your review + star rating, I really appreciate it!

  2. Since it is a bit cooler today, I was looking for something macro friendly besides my normal overnight oats and came across this recipe. I cut the maple syrup down to 1 tsp, eliminated the walnuts to decrease the fat content, and used a scoop of collagen powder in place of the protein. I also made sure to use peanut butter because banana and peanut butter just go together! This was absolutely delicious and plenty sweet with the decreased maple syrup. I will definitely be making this again!

    1. Woo!! So excited to hear you enjoyed this recipe, Wendy. Thanks for the review. I really appreciate the feedback!
