Ingredients & Substitutions
Old-fashioned rolled oats: These are the star of the show! They give the oatmeal a chewy texture. If you don’t have them, quick oats will work, though the texture will be softer.
Brown sugar: It adds a nice caramel flavor. You can substitute it with coconut sugar or white sugar, but the taste will vary slightly. For a healthier option, try maple syrup—just reduce the milk a bit.
Cinnamon: This ingredient gives the recipe that classic cinnamon roll taste. If you want a twist, you can use apple pie spice or pumpkin pie spice instead for a different flavor profile.
Milk: Regular milk works nicely, but feel free to use almond, oat, or soy milk if you prefer a dairy-free version. Each has its own flavor, so consider what you enjoy most!
Egg: If you’re vegan, you can replace the egg with a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water) or applesauce (1/4 cup). Both options will keep it moist.
How Do I Get the Perfect Cinnamon Swirl?
Creating that delightful cinnamon swirl is easier than you think! You’ll want the mixture to be evenly spread but still swirled for that perfect look.
- Combine the brown sugar, cinnamon, and melted butter in a bowl. This blend creates a paste-like filling.
- After pouring half of the oat mixture in the baking dish, sprinkle the cinnamon mixture evenly on top.
- Pour the remaining oat mixture over it, then use a knife or skewer to gently swirl through both layers—don’t mix it all together, just create a beautiful pattern!
Taking your time with this step will ensure every bite has that warm, cinnamon flavor you crave! Enjoy your delicious baked oatmeal!

How Much Time Will You Need?
This recipe takes about 15 minutes to prep and 35-40 minutes to bake, for a total of around 55-60 minutes. The warm, gooey oatmeal will be ready in no time!
Step-by-Step Instructions:
1. Preheat and Prepare:
First, preheat your oven to 375°F (190°C). This ensures that your baked oatmeal cooks evenly. Grease a 9-inch round baking dish (or similar oven-safe dish) to prevent sticking later on.
2. Mixing the Dry Ingredients:
In a large bowl, mix together the old-fashioned rolled oats, packed brown sugar, baking powder, ground cinnamon, and salt. This will be the base of your oatmeal, providing all the flavor and texture!
3. Combining the Wet Ingredients:
In another bowl, whisk together the milk, egg, melted butter, and vanilla extract. This mixture adds moisture and flavor to your baked oatmeal.
4. Combine Wet and Dry:
Pour the wet ingredients into the dry ingredients and stir everything together until fully combined. It should look well mixed and ready for baking!
5. Layering the Oat Mixture:
Pour half of the oat mixture into the prepared baking dish and spread it out evenly. This starts your cinnamon layers.
6. Adding the Cinnamon Swirl:
In a small bowl, mix together the brown sugar, ground cinnamon, and melted butter for that gooey swirl. Sprinkle this mixture evenly over the oat layer to create a sweet surprise!
7. Top it Off:
Now, pour the remaining oat mixture over the cinnamon swirl layer and spread gently to cover. Be careful not to disturb the swirl too much!
8. Create the Marble Effect:
Using a knife or skewer, gently swirl the mixtures together, creating a marbled cinnamon effect. This step gives you those delicious cinnamon pockets throughout the oatmeal!
9. Baking:
Now, it’s time for the oven! Bake for 35-40 minutes, until the oatmeal is set and the top is lightly browned. Your kitchen will smell amazing!
10. Preparing the Glaze:
While your oatmeal is baking, make the glaze. In a small bowl, whisk together the powdered sugar, milk (or cream), and vanilla extract until it’s smooth and drizzly.
11. Cool It Down:
Once your baked oatmeal is out of the oven, let it cool for about 5 minutes. This helps it set and makes it easier to serve.
12. Drizzle and Serve:
Finally, drizzle the glaze over the warm oatmeal right before serving. This adds a sweet finishing touch. Enjoy your warm, comforting Cinnamon Roll Baked Oatmeal as a delicious start to your day!
Can I Use Steel-Cut Oats Instead of Rolled Oats?
For this recipe, it’s best to stick with old-fashioned rolled oats. Steel-cut oats require a longer cooking time and won’t give you the same soft texture. If you only have steel-cut oats, consider soaking them overnight to help with cooking.
How to Store Leftovers?
You can store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, just pop it in the microwave or warm it up on the stove, adding a splash of milk to restore moisture.
Can I Make This Recipe Vegan?
Absolutely! To make it vegan, substitute the egg with a flax egg (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water) and use plant-based milk and butter. It will still taste delicious!
How Can I Customize the Flavor?
Feel free to mix it up! You can add nuts, dried fruit, or chocolate chips for extra flavor. Just remember, if you add additional ingredients, you may want to adjust the baking time slightly to ensure it’s cooked through.
