Cinnamon Roll Overnight Oats

As a dietitian, I fully understand the value of prepping healthy meals in advance, even if I’m not the most consistent about doing it for myself. Still, future hungry me is always glad when I take a few minutes to mix up a batch of overnight oats. Especially in warmer months when a hot breakfast feels too heavy (and honestly like too much work), having something cold, creamy and ready to go straight from the fridge makes mornings a whole lot easier.

These cinnamon roll overnight oats deliver all the cozy, spiced flavor of ooey-gooey cinnamon rolls in a lighter make-ahead breakfast. The overnight oats are simple, satisfying and just a little bit indulgent, while still being a balanced, energizing way to start the day. They are a perfect example of how a little advance effort can pay off with a breakfast that feels both nourishing and genuinely delicious.

Ingredients for Cinnamon Roll Overnight Oats

• Old-fashioned oats: Also known as rolled oats, old-fashioned oats are the best choice for overnight oats since they soften while still keeping a little chew, so they don’t turn mushy. Quick oats break down too much, and steel-cut oats stay too firm.
• Brown sugar: Dessert-inspired oats need a touch of sweetness, and brown sugar enhances that warm, spiced vibe with a hint of molasses. You can sweeten them with maple syrup for a slightly different flavor, but honey or granulated sugar won’t deliver the same depth.
• Ground flaxseed: Flax adds a boost of fiber and helps thicken the oats as they chill. If you don’t have it, you can skip it or swap in chia seeds for a similar effect.
• Cinnamon: Don’t be shy with the ground cinnamon here! It’s what gives these overnight oats their signature cinnamon roll flavor.
• Plant-based milk: Vanilla-flavored soy or oat milk adds a subtle sweetness and extra flavor. Regular dairy milk also works well and makes the oats a bit higher in protein.
• Vanilla Greek yogurt: Greek yogurt gives the oats a thick, creamy texture and adds protein, making them more satisfying. Vanilla yogurt leans into the dessert-like flavor, but plain works too if that’s what you have.
• Vanilla extract: Just a splash rounds out the other flavors and helps the oats taste even more like a cinnamon roll straight from the bakery.

Directions

Step 1: Whisk the dry ingredients

In a small bowl, whisk together the oats, brown sugar, ground flaxseed and cinnamon.

Editor’s Tip: For extra flavor and a hint of nuttiness, toast the oats in a dry skillet over medium-low heat until just golden.

Step 2: Stir in the wet ingredients

Add the milk, Greek yogurt and vanilla extract to the oat mixture. Stir until the mixture is evenly combined and no dry pockets remain.

Step 3: Portion and chill

Divide the mixture into jars or containers with lids. Cover and refrigerate overnight to let the oats soften. If desired, garnish the oats with a cinnamon stick before serving.​

Editor’s Tip: If the oats seem too thick before serving, add an extra splash of milk to loosen, then add any desired toppings.

Recipe Variations

• Boost the protein: Swap in a high-protein Greek yogurt, add a tablespoon of nut butter or stir in a scoop of vanilla protein powder for extra protein. If using protein powder, you may need an extra splash of milk to bring everything together.
• Finish with “icing”: Mix a spoonful of softened cream cheese with a drizzle of maple syrup, then swirl it over the oats before serving for a classic iced cinnamon roll feel.
• Make them fruity: Stir in a small handful of raisins before chilling for extra sweetness and texture, or try finely diced apples or a spoonful of pumpkin puree for a cozy fall-inspired flavor.
• Add some crunch: Top with toasted chopped pecans or walnuts for nuttiness and a little crunchy contrast.

How to Store Cinnamon Roll Overnight Oats

Keep cinnamon roll overnight oats in airtight jars or containers in the refrigerator. For the best flavor and texture, enjoy them within one to three days. Any longer than that and the oats will continue to soften and thicken, becoming a bit mushier.

Can you freeze cinnamon roll overnight oats?

Yes, you can freeze cinnamon roll overnight oats for up to two months. Freeze them in airtight, freezer-safe containers, then transfer them to the fridge to thaw overnight before eating. The texture may be a bit softer after thawing, but the cinnamon flavor will still shine through.

Can you make cinnamon roll overnight oats ahead of time?

Absolutely! Like other overnight oats, this cinnamon roll version is a great make-ahead breakfast. Prepare a few jars at once and keep them in the refrigerator for grab-and-go breakfasts.

Cinnamon Roll Overnight Oat Tips

Can you make cinnamon roll overnight oats with regular milk?

Yes! Regular milk works just as well as nondairy milk in these cinnamon roll overnight oats. Whole milk will give the oats a richer, creamier texture, while lower-fat milk keeps the flavor and texture a bit lighter. Feel free to use whatever milk you typically have on hand.

Since this recipe calls for vanilla-flavored dairy-free milk, you may want to add an extra splash of vanilla extract if using plain cow’s milk to help create that cozy, freshly baked cinnamon roll vibe.

What toppings go well with cinnamon roll overnight oats?

Honestly, these cinnamon roll overnight oats are delicious on their own, but a few simple toppings can make them even more satisfying. Try fresh berries for a bright pop of flavor, granola or chopped nuts for crunch, or a drizzle of honey or maple syrup for extra sweetness. For something extra-creamy and indulgent, add a dollop of yogurt or even a spoonful of whipped cream on top.

Can you serve cinnamon roll overnight oats warm?

Yes! While overnight oats are traditionally served cold, you can absolutely serve them warm like a regular bowl of oatmeal. Warming them brings out the cinnamon flavor and makes each spoonful feel even more like a fresh-from-the-oven treat.

Heat the oats in the microwave in 30-second intervals, stirring after each, until warmed through. Since the oats thicken as they sit in the fridge, stir in a splash of milk before heating.
