Cinnamon Roll Baked Oatmeal For One topped with an almond butter cinnamon swirl and protein powder icing. The perfect single serve recipe for when you crave a cinnamon bun and oats for breakfast at the same time!

This “bowl” of cinnamon roll oats was ginormous! The first time I made it, I used a regular ramekin and took it out of the bowl for the shoot – to make it resemble a cinnamon roll.

But it wasn’t really as pretty. So the next round I used almost the same ratios, but in this wider – and shallower – dish. My did that thing rise!?

Omigosh I just realized, a real baked cinnamon roll – oats or not – is supposed to rise too haha.

Ingredients for Single Serve Cinnamon Roll Baked Oatmeal

This healthy baked cinnamon roll oatmeal uses no oil, no butter, no milk, no added sugar, just clean ingredients.

Instant or Quick Oats
Unflavored (Whey) Protein Powder to for smoothness and make this a high protein oatmeal recipe. I use Quest Nutrition’s Multi-purpose Mix.
You can also replace it with oat flour or almond flour.
Flaxseed Meal: Making this cinnamon roll oatmeal with flaxseeds keeps it Vegan and also adds some fiber in.
Cinnamon for a good cinnamon oatmeal flavor.
Baking Powder: Try to go low sodium if possible.
Unsweetened Almond Milk to keep the baked oatmeal dairy free and sugar free, but use regular milk if you wish.
Applesauce or Mashed Banana: to add natural sweetness and also a creamy texture. Now you have a Vegan cinnamon roll baked oats with no eggs.
Optionally, Maple Syrup: I recommend a stevia or monk fruit sweetened one to keep the baked oatmeal sugar free and low calorie.

For the sugar-free cinnamon swirl:

Creamy Almond Butter
Cinnamon
Maple Syrup

How to make Cinnamon Bun Baked Oats for One

This cinnamon roll oatmeal bake is super easy to make!

Start with preheating your oven to 350°F.

Bowl 1 (small): Mix together all the dry ingredients – oats, unflavored protein powder or almond/oat flour, flaxseed meal and baking powder, until uniform.
Bowl 2 (medium): Whisk all the wet ingredients – milk, applesauce or mashed banana, and maple syrup if using
Add dry mix (2) to wet mix (1) and stir until the mix is uniform.
Grease a large ramekin or oven-safe dish with coconut oil or cooking spray. You want one that’s about 1½ cups or 12 ounces in volume.
Pour mixture into the ramekin.
Bake 27-30 minutes. The top of the oats should be just set. Don’t over bake it or the bottom and sides will completely dry out.

Cinnamon Baked Oatmeal with Whey Protein Powder Icing

To keep them healthy, and make them even better and healthier, I topped these baked cinnamon oats with icing made from protein powder.

This protein powder icing is extremely simple: Just stir together protein powder and a little bit of milk or water.

You want a thick and spreadable protein powder frosting that you can then use on smear on top of the oats.

This is another one of my Quest protein powder recipes! Use Vegan protein powder like Orgain to make it diet compliant.

Tips for this Single Serve Cinnamon Roll Baked Oats

Use Instant or Quick Oats – I use the instant oats since they’re a bit finer and give a texture when baked – rolled oats would make it more chewy.
If rolled oats is all you have, blend it in a food processor for a bit so it shreds a little. Be sure to use gluten free oats if you need.
Be sure to mix the dry ingredients so the protein powder or oat/almond flour gets all around. You want a smooth texture and good rise.
Don’t add too much liquid or the top will be too soft. You would need to bake it longer to get it to firm up, but this would make the sides dry out.

Can you store Cinnamon Bun Baked Oatmeal?

Just like a regular baked oatmeal, this single serving cinnamon bun oatmeal also keeps.

You can keep the baked oats in the fridge in an airtight container and it should be fine for 3-4 days. Be sure to only add the icing when serving.

Microwave it to reheat – about 45 seconds to a minute should be good.

For longer-term storage, this peanut butter baked oatmeal is freezer friendly! Freeze the baked oats in zipper bags and they should last about 2-3 months. Reheat in a 350°F oven for about 20 minutes until its warmed though, or use a microwave.

Again, frost/ice it when you’re ready to eat!

You can also size up the quantities of this baked oat recipe and use a muffin tin to make cinnamon roll oatmeal cups or muffins or a baking sheet to make cinnamon baked oatmeal bars.

Double up and make baked oatmeal for two. They all freeze really well!
