Tiramisu Overnight Oats

My roommate walked into the kitchen at 11 PM one night, half-asleep but determined to bake something Italian and elaborate. I convinced her that overnight oats could capture that same tiramisu magic, and honestly, I think we both preferred waking up to breakfast instead of standing over a stove at midnight.

I started making these during my first real job, when I needed something that felt indulgent but could be assembled in exhausted minutes. Now they are my go-to when I want to feel fancy before 8 AM without any actual effort.

Ingredients

• Old-fashioned rolled oats: These absorb the liquid beautifully while maintaining some chew, unlike instant oats which can turn mushy
• Milk: Dairy adds creaminess but oat milk works surprisingly well and keeps it plant-based
• Greek yogurt: This is what gives us that mascarpone-like tang and protein boost
• Chia seeds: They thicken everything while adding omega-3s and a nice texture
• Maple syrup or honey: Just enough sweetness to balance the bitter espresso
• Vanilla extract: Dont skip this, it bridges the gap between breakfast and dessert flavors
• Brewed espresso: Strong coffee works, but espresso really nails that authentic tiramisu taste
• Mascarpone cheese: The real star ingredient, though cream cheese makes a decent backup
• Cocoa powder: Dutch-process cocoa gives the smoothest, richest chocolate flavor
• Dark chocolate shavings: These are optional but they make everything feel a little more special

Instructions

Mix the oat base:

Combine oats, milk, yogurt, chia seeds, sweetener, and vanilla in a bowl until everything is well incorporated and the chia seeds are distributed evenly

Prepare the tiramisu layer:

Whisk together espresso, mascarpone, cocoa powder, and sweetener until you have a smooth, chocolatey mixture without lumps

Layer it up:

Spoon half the oats into two jars, add half the tiramisu mixture, then repeat with remaining oats and topping mixture

Let it work its magic:

Cover and refrigerate for at least 8 hours, giving the oats time to soften and absorb all those delicious flavors

Add the finishing touches:

Dust with cocoa powder and scatter chocolate shavings on top right before serving

My sister-in-law tried these during a weekend visit and immediately demanded the recipe. She texts me photos of her layered jars, always with a little more cocoa dusting than mine, and I love that this tiny recipe has become our thing.

Make Ahead Magic

I typically prepare two jars on Sunday evening, and honestly, having Monday breakfast sorted makes the whole week feel more manageable. The oats actually improve after 24 hours as the flavors meld together, though I try to finish them within two days for the best texture.

Playing with Variations

Sometimes I swap in almond butter for a nutty version, or add a pinch of cinnamon to the oat base. During berry season, fresh raspberries tucked between layers create this incredible fruit and chocolate moment that reminds me of chocolate-covered strawberries.

Serving Suggestions

These are perfect for meal prep, busy mornings, or when you want breakfast to feel special without any morning work. The jars travel well, making them ideal for office breakfasts or early flights.

• Use wide-mouth jars for easier layering and cleaning
• Save your chocolate shavings in a small container so they stay fresh
• The topping layer gets even better if you add it right before eating

Save

There is something deeply satisfying about waking up to a breakfast that tastes like a famous Italian dessert but still counts as a healthy start to the day. I hope these bring a little morning joy to your kitchen too.

Recipe FAQs

These oats are best enjoyed within 2 days when stored properly in sealed containers in the refrigerator. The textures remain optimal, and flavors continue to develop during this time.

→ What's the best way to make this vegan?

Use plant-based milk like oat or almond milk, coconut yogurt instead of Greek yogurt, and vegan cream cheese or cashew cream in place of mascarpone. Maple syrup works perfectly as a natural sweetener.

→ Can I prepare this in advance for meal prep?

Absolutely. Assemble multiple jars at once and store them in the refrigerator for up to 2 days. The layers will maintain their structure, and flavors will actually improve after resting overnight.
