Tiramisu overnight oats combine rolled oats soaked in coffee-spiked milk with a velvety mascarpone layer, all finished with a dusting of cocoa powder. Prep takes just 10 minutes the night before, and the oats soften beautifully while chilling in the fridge.
Each jar delivers the classic flavors of tiramisu — bold espresso notes, creamy mascarpone, and bittersweet cocoa — in a wholesome, vegetarian-friendly format perfect for busy mornings or an elegant brunch.
My alarm went off at 5:47 am on a rainy Tuesday, and the only thought that dragged me out of bed was knowing a jar of tiramisu overnight oats was waiting in the fridge. The combination of cold brew and cocoa hit me the moment I twisted the lid, and honestly, it felt like eating dessert at dawn. That first spoonful changed my entire morning routine. I have not gone back to plain oatmeal since.
I brought two jars to a friend who had just had her second baby, and she texted me three days later asking if I could make it weekly. There is something about handing someone a breakfast that feels like a treat rather than an obligation. She told me she ate it standing over the kitchen sink at 3 am during a feeding session and it was the best thing she had tasted in weeks. That is the highest compliment I can imagine.
Ingredients
- Rolled oats (1 cup): Use old fashioned rolled oats rather than quick oats because they hold their chew overnight without turning to paste.
- Milk (1 cup): Whole milk gives the creamiest result, but oat milk or almond milk work beautifully if you want to keep it lighter.
- Plain Greek yogurt (1/2 cup for base, 2 tbsp for mascarpone layer): This adds tang and body, and the extra protein keeps you full well past noon.
- Chia seeds (2 tbsp): They are the secret weapon here, creating that luxurious thick texture as they absorb liquid overnight.
- Maple syrup or honey (2 tbsp plus 1 tbsp): Split between the oat base and the mascarpone layer for balanced sweetness throughout.
- Vanilla extract (1 tsp): A small amount goes a long way in adding warmth and rounding out the coffee flavor.
- Strong brewed coffee, cooled (1/4 cup): Espresso is ideal if you have it, but any strong brew will give you that authentic tiramisu depth.
- Mascarpone cheese (1/4 cup): This is what pushes it from regular oats into something that feels like a genuine Italian dessert.
- Unsweetened cocoa powder (2 tbsp for dusting): Use a fine mesh sieve to get an even, delicate layer on top.
- Dark chocolate shavings (optional): A handful of curls on top adds a satisfying bit of texture and bitterness.
Instructions
- Build the oat foundation:
- Grab a medium bowl and stir together the oats, milk, yogurt, chia seeds, maple syrup, and vanilla until everything is evenly combined and there are no dry pockets hiding at the bottom.
- Add the coffee:
- Pour the cooled brewed coffee over the oat mixture and stir gently, taking a moment to appreciate how the aroma shifts as the coffee blends in.
- Layer into jars:
- Divide the oat mixture evenly between two jars or lidded containers, tapping them gently on the counter to settle the contents and remove air bubbles.
- Whip the mascarpone topping:
- In a small bowl, blend the mascarpone, Greek yogurt, and remaining maple syrup with a fork or small spatula until silky smooth and spreadable.
- Crown each jar:
- Spoon the mascarpone mixture over the oats in each jar, smoothing the top with the back of your spoon so it forms a neat, even layer.
- Let the fridge work its magic:
- Seal the jars tightly and tuck them into the refrigerator for at least six to eight hours, ideally overnight, so the oats soften and the flavors deepen.
- Finish and serve:
- Just before eating, use a fine sieve to dust the tops generously with cocoa powder and scatter chocolate shavings over the surface if you are feeling fancy.
One Saturday morning my nephew wandered into the kitchen, spotted the cocoa dusted jars, and asked if we were having cake for breakfast. I handed him a spoon and watched his face shift from suspicion to pure joy. Sometimes the best meals are the ones that make you question whether you are getting away with something.
Making It Your Own
This recipe bends easily to whatever you have on hand. I have swapped the mascarpone for ricotta when the grocery store was out, and while it was slightly less rich, the lemony undertone was actually a lovely surprise. Coconut cream works if you want to go fully dairy free, though it will lean sweeter and more tropical than traditional tiramisu. The bones of the recipe are forgiving enough that you can play around without worrying about breaking it.
When to Make It
Sunday evening is my favorite time to assemble these because the whole process takes less time than brewing a second pot of coffee, and then breakfast is handled before Monday even begins. They also make a wonderful midnight snack after a long day. I have served them at brunch gatherings in small glasses with little spoons, and people always ask for the recipe. Any occasion that calls for something a little special without any real effort is the right occasion.
Storage and Leftovers
The oats will keep well in the fridge for up to three days, though the texture is at its best within the first two. Hold off on adding the cocoa dusting and chocolate shavings until right before eating so they do not dissolve into the mascarpone layer overnight.
- Give the jar a quick stir if any liquid has settled at the bottom after a day or two.
- Avoid freezing because the yogurt and mascarpone will separate and turn grainy when thawed.
- Always use a clean spoon when eating directly from the jar to keep the remaining portion fresh.
There is a quiet kind of happiness in opening the fridge and finding something delicious already waiting for you, especially when that something tastes like tiramisu. This recipe is a small act of self care disguised as breakfast, and you deserve that.
Recipe Questions & Answers
- → Can I make tiramisu overnight oats dairy-free?
-
Absolutely. Swap the Greek yogurt for coconut yogurt and replace mascarpone with a vegan cream cheese or blended silken tofu sweetened with maple syrup. Use a plant-based milk like oat or almond milk for the soaking liquid.
- → How long do these oats last in the fridge?
-
They store well for up to 3 days when kept sealed in airtight jars. The oats may thicken over time — simply stir in a splash of milk before eating to reach your preferred consistency.
- → Do I need to use espresso or will regular coffee work?
-
Regular brewed coffee works perfectly fine and is what the preparation calls for. If you want a more intense coffee flavor reminiscent of traditional tiramisu, you can substitute an equal amount of cooled espresso.
- → Can I warm these oats instead of eating them cold?
-
Yes, you can microwave them for about 60 to 90 seconds if you prefer a warm breakfast. Keep in mind the mascarpone topping will soften and melt slightly, creating a creamier texture throughout.
- → What can I use instead of chia seeds?
-
Ground flaxseed works as a direct substitute and provides similar thickening power. You can also simply omit them, though the final texture will be slightly less pudding-like and more loose.
