Tasty Cinnamon Roll Overnight Oats

I’ve never been a morning person, but I’ve always loved cinnamon rolls. The problem? Who has time to make them from scratch when you can barely open your eyes before 8 AM? I spent years wishing I could have that warm, cinnamon-sugar taste without all the work.

That’s when I discovered overnight oats. I can mix everything up the night before, and by morning, I have something that tastes like a cinnamon roll but feels way better about eating for breakfast. I prep these on Sunday nights and have breakfast ready for the whole week. No early morning baking required.

The best part is how the oats soak up all those cinnamon flavors overnight. You get that sweet, comforting taste of a cinnamon roll, but you’re actually eating something that will keep you full until lunch. It’s like having dessert for breakfast, except it’s actually good for you.

What Kind of Oats Should I Use?

For overnight oats, you’ll want to stick with old-fashioned rolled oats rather than quick oats or steel-cut oats. Old-fashioned oats have the perfect texture that softens nicely overnight without turning mushy, giving you that ideal creamy yet slightly chewy bite in the morning. Quick oats will break down too much and become gummy, while steel-cut oats won’t soften enough during the soaking time. You can find old-fashioned oats in any grocery store, and they’re usually labeled clearly on the container – just look for the larger, flatter oat flakes rather than the smaller, more processed ones.

Options for Substitutions

This recipe is super adaptable to whatever you have in your pantry:

• Old-fashioned oats: Stick with old-fashioned oats for the best texture – quick oats will get too mushy overnight, and steel-cut oats won’t soften enough.
• Non-dairy milk: Any plant-based milk works great here! Almond milk keeps it light, oat milk adds creaminess, and soy milk gives you extra protein. You can even use regular dairy milk if that’s what you prefer.
• Coconut yogurt: Feel free to use any plant-based yogurt you like – almond, cashew, or oat-based all work well. Greek yogurt is fine too if you’re not avoiding dairy.
• Chia seeds and flaxseed: These add nutrition and help thicken the oats, but you can skip them if you don’t have them on hand. The oats will just be a bit thinner.
• Brown sugar: Maple syrup, honey, or coconut sugar work as great substitutes. Start with less since liquid sweeteners can make the mixture runnier.
• Maple syrup: Honey, agave, or even a bit more brown sugar can replace the maple syrup in the topping.

Watch Out for These Mistakes While Cooking

The biggest mistake with overnight oats is using quick oats instead of old-fashioned rolled oats, which will turn your breakfast into a mushy porridge rather than maintaining that nice chewy texture you want.

Another common error is not using enough liquid – if your oats look too thick in the morning, simply stir in a splash more non-dairy milk until you reach your preferred consistency.

Don’t skip the resting time either, as overnight oats need at least 4 hours (but preferably 8-12 hours) in the fridge to properly soften and develop their creamy texture.

For the best cinnamon roll flavor, make sure to mix the cinnamon and brown sugar thoroughly with the dry ingredients before adding the wet ones, and give everything a good stir before refrigerating to prevent clumping.

What to Serve With Cinnamon Roll Overnight Oats?

These overnight oats are pretty filling on their own, but I love adding some fresh fruit on top like sliced bananas, berries, or diced apples for extra sweetness and crunch. A handful of chopped walnuts or pecans also makes a great topping that plays perfectly with the cinnamon flavors. If you want to make it feel more like an actual cinnamon roll, try drizzling a little extra maple syrup on top or adding a sprinkle of powdered sugar. For a more substantial breakfast, you could serve it alongside some scrambled tofu or a piece of whole grain toast.

Storage Instructions

Refrigerate: These overnight oats are perfect for meal prep! Store them in mason jars or airtight containers in the fridge for up to 5 days. I love making a whole week’s worth on Sunday so I have breakfast ready to grab and go every morning.

Make Ahead: The beauty of overnight oats is that they actually get better after sitting overnight. Make them at least 4 hours ahead, but they’re at their creamiest after 8-12 hours in the fridge. You can even make individual portions in small jars for easy weekday breakfasts.

Serve: Enjoy your cinnamon roll oats straight from the fridge, or let them sit at room temperature for a few minutes if you prefer them less cold. Give them a good stir before eating and add any extra toppings you like. They’re meant to be eaten cold, so no heating needed!

Ingredients

For the overnight oats:

• 1 tsp ground cinnamon (freshly ground for best flavor)
• 1 cup non-dairy milk (soy, almond, or oat milk work well)
• Pinch salt
• 2 tbsp coconut yogurt (or any plant-based yogurt)
• 1 tsp chia seeds
• 1 tsp vanilla extract (pure vanilla preferred)
• 1 tbsp flaxseed meal (I use Bob’s Red Mill)
• 2 tbsp light brown sugar (packed)
• 1 cup rolled oats (old-fashioned preferred for better texture)

For the optional topping:

• 1/2 tsp fresh lemon juice (brightens the frosting)
• 1 tsp oat milk (or any plant-based milk to reach desired consistency)
• 1/2 tsp pure maple syrup (adds authentic sweetness)
• 1 tbsp coconut yogurt

Step 1: Combine Dry Ingredients and Build the Flavor Base

• 1 cup rolled oats
• 2 tbsp light brown sugar
• 1 tsp ground cinnamon
• 1 tsp chia seeds
• 1 tbsp flaxseed meal
• Pinch salt

In a medium bowl, whisk together the rolled oats, light brown sugar, ground cinnamon, chia seeds, flaxseed meal, and salt.

This initial mixing ensures the cinnamon and sweetness distribute evenly throughout the oats rather than settling at the bottom—a key step for consistent flavor in every spoonful.

The dry mixture is now ready to receive the wet ingredients.

Step 2: Create the Creamy Base and Combine

• dry ingredient mixture from Step 1
• 1 cup non-dairy milk
• 2 tbsp coconut yogurt
• 1 tsp vanilla extract

Add the non-dairy milk, 2 tbsp coconut yogurt, and vanilla extract to the dry ingredient mixture from Step 1.

Stir thoroughly until all the oats are evenly moistened and no dry pockets remain.

The mixture should look wet but not soupy—the oats will continue to absorb liquid as they sit overnight.

Divide the mixture evenly between two mason jars or containers.

Step 3: Chill Overnight to Develop Texture

Cover the jars and refrigerate for at least 4 hours, but preferably overnight.

During this time, the oats absorb the liquid and soften while the flavors meld together, creating a creamy, pudding-like consistency.

I find overnight chilling gives you a much better texture than just 4 hours, so plan ahead when possible.

Step 4: Adjust Consistency and Prepare to Serve

• chilled oat mixture from Step 2
• non-dairy milk

Remove the jars from the refrigerator and stir the oats well.

If the mixture has thickened too much overnight, add more non-dairy milk a splash at a time until you reach your desired consistency—some people prefer thick and spoonable, others like it more pourable.

Taste a small spoonful to check the flavor intensity; the cinnamon should be pleasantly present but not overpowering.

Step 5: Make the Maple Frosting and Finish

• 1 tbsp coconut yogurt
• 1/2 tsp pure maple syrup
• 1/2 tsp fresh lemon juice
• 1 tsp oat milk

In a small bowl, whisk together 1 tbsp coconut yogurt, pure maple syrup, and fresh lemon juice until smooth.

The lemon juice adds a subtle brightness that balances the richness and prevents the frosting from tasting one-dimensional.

If the mixture is too thick, add 1 tsp of oat milk to reach a drizzleable consistency.

Drizzle this maple frosting generously over the top of each jar of oats just before eating.

I like to give it one more gentle stir to incorporate some of the frosting into the oats while leaving ribbons of it visible on top.
