Tiramisu Overnight Oats

Last winter, during that stretch of gray February mornings when coffee felt like my only motivation, I started experimenting with breakfast ideas that actually made me want to get out of bed. The idea came to me while standing in my kitchen at 6am, watching steam rise from my espresso maker and wishing dessert was an acceptable breakfast. Something clicked when I dipped my spoon into leftover tiramisu the night before and thought why not combine these two things.

My sister was visiting that first week I tested this recipe, and she sent me a text at 7am from her room saying she could smell coffee and chocolate from downstairs. We ended up eating them on my balcony wrapped in blankets while the frost was still melting off the railing. She made me promise to write down the recipe before she left, and now she makes them every Sunday night for the week ahead.

Ingredients

• 1 cup old-fashioned rolled oats: These hold up better overnight than instant oats and give you that satisfying chewy texture
• 1 cup milk: Dairy milk makes it creamier but oat milk works beautifully if you want to keep it plant based
• 1/2 cup plain Greek yogurt: This is what gives you that protein boost and mimics the mascarpone richness
• 2 tbsp chia seeds: They soak up all the flavors and thicken everything beautifully while you sleep
• 2 tbsp maple syrup or honey: Start here and adjust later, you can always add more but you cannot take it back
• 1 tsp pure vanilla extract: Do not skip this, it is what ties all the flavors together
• 1/4 cup strong brewed espresso: Brew it extra strong and let it cool completely before using
• 2 tbsp mascarpone cheese: The real deal makes all the difference but cream cheese works in a pinch
• 1 tbsp cocoa powder plus more: Use unsweetened Dutch process for the deepest chocolate flavor
• 1 tbsp maple syrup: For the tiramisu layer
• Dark chocolate shavings: These are optional but honestly they make the whole thing feel special

Instructions

Mix the oat base:

Combine your oats, milk, yogurt, chia seeds, maple syrup, and vanilla in a medium bowl. Stir until everything is well incorporated and the chia seeds are not clumped together at the bottom.

Prepare the tiramisu layer:

In a separate small bowl, whisk together the cooled espresso, mascarpone, cocoa powder, and remaining maple syrup until you have a smooth, chocolatey mixture.

Start the layers:

Spoon half of your oat mixture into two jars or glass bowls. Spread it out gently so it creates an even base.

Add the magic:

Divide the tiramisu layer between your two jars, spreading it carefully over the oats. Do not worry if it is not perfect, the layers will meld together beautifully overnight.

Repeat the layers:

Add the remaining oat mixture on top of each jar, then finish with the rest of the tiramisu layer.

Let it rest:

Cover your jars and place them in the refrigerator for at least 8 hours. The chia seeds will work their magic and everything will thicken up.

The finishing touch:

Right before serving, dust the top with extra cocoa powder and add those chocolate shavings if you are feeling fancy.

These became my go-to during finals week last semester when I needed something that felt indulgent but would not leave me crashing by 10am. My roommate started requesting them too, and we had this silent morning routine of grabbing our jars from the fridge and eating while studying at the kitchen table.

Make It Your Own

I have played around with different coffee varieties, and a dark roast gives you that bold espresso flavor while a lighter roast tastes more subtle and sweet. Sometimes I add a pinch of cinnamon to the oat base when I want something that feels a bit cozier, especially on rainy mornings.

Storage And Timing

The texture is best within the first two days, so I usually make a double batch on Sunday night and they last me through Tuesday morning. You can prep everything in reusable glass jars which makes mornings feel like you have your own personal meal prep service.

Serving Ideas

I have served these at brunch and people genuinely thought they were dessert, which might be the highest compliment I have ever received. They pair beautifully with fresh berries if you want something tart to cut through all that richness.

• Try stirring a tablespoon of coffee liqueur into the tiramisu layer for a grownup version
• Top with chopped toasted hazelnuts for that classic Italian combination
• Serve with a shot of fresh espresso on the side for the full experience

There is something about waking up knowing breakfast is already handled that makes the whole day feel more manageable. I hope these bring a little moment of luxury to your mornings too.

Your Recipe Questions

→ How long do these overnight oats keep?

These layered oats stay fresh in the refrigerator for up to 2 days. The textures remain creamy and the flavors continue to meld, making them perfect for meal prep.

→ Can I make this dairy-free?

Absolutely. Substitute dairy milk with almond, oat, or coconut milk, swap Greek yogurt for coconut yogurt, and use vegan cream cheese instead of mascarpone.

→ Is there a way to reduce the caffeine?

You can use decaffeinated espresso or coffee, or simply reduce the amount to 1-2 tablespoons while maintaining the same proportion of other ingredients.

→ What type of oats work best?

Old-fashioned rolled oats are ideal as they soften perfectly overnight. Steel-cut oats will remain too chewy, while instant oats may become too mushy.

→ Can I prepare this warm instead?

This version is designed for overnight soaking. For warm preparation, try cooking the oats on the stovetop and stirring in the espresso-mascarpone mixture just before serving.
