Tiramisu Overnight Oats bring together the creamy, coffee-flavored goodness of classic tiramisu in a simple, healthy breakfast. This dish combines oats soaked overnight with espresso or strong coffee, sweet mascarpone or cream cheese, and a sprinkle of cocoa powder on top, giving you all the familiar flavors without the fuss of baking.

I love making these oats the night before because they’re ready to eat as soon as I wake up—no morning rush, just a delicious, comforting bowl waiting for me. The hint of coffee mixed with sweet cream always feels like a little treat, and it’s a great way to start the day with some energy and a bit of indulgence. I also like to add a few chocolate chips or a dusting of cinnamon for a personal touch.

Serving this with some fresh berries or a sprinkle of crushed nuts makes it even more special, adding texture and a fresh brightness that balances the richness. It’s a nice change from your usual breakfast routine and always gets compliments from anyone who tries it. Plus, it’s an easy way to enjoy tiramisu flavors any time of day without the calories or effort of a traditional dessert.

Key Ingredients & Substitutions

Rolled oats: These are great for soaking up flavors while staying soft but still a bit chewy. If you want a quicker soak, use instant oats but be aware the texture changes to mushier.

Chia seeds: They add a nice thickening effect and a bit of crunch. If you don’t have chia, ground flaxseeds work well as a substitute and add fiber too.

Greek yogurt or mascarpone: This gives creaminess and richness. Greek yogurt is lighter and tangy, while mascarpone is richer and more traditional to tiramisu. Use whatever feels right for you.

Strong coffee or espresso: The heart of the tiramisu flavor. Brew fresh and cool it before using. Decaf is a good option if you want to avoid caffeine.

Sweetener: Maple syrup or honey works well here. Choose based on your taste and dietary needs. Agave nectar or a sugar substitute can also work.

How Do I Layer and Soften the Oats Perfectly Overnight?

Layering helps keep the distinct coffee and creamy oat flavors separate for a nice visual and taste experience. To get a smooth, creamy texture:

Mix the oat base ingredients well before layering to make sure oats and chia seeds will soak evenly.
Pour the coffee-cocoa mix evenly over half the oat base so it seeps gently through but keeps the layers distinct.
Top with the remaining oat mixture to give a creamy top layer.
Refrigerate uncovered for about 10 minutes to let coffee soak in a bit, then cover and leave overnight.
This slow soak helps oats absorb without becoming too soggy and lets flavors meld nicely.

When you’re ready to eat, stir gently or enjoy layers as they are. The cocoa dusting on top adds a little bitterness that balances the sweet and creamy bottom.

Equipment You’ll Need

Mason jars or small glass containers – perfect for layering and easy to store in the fridge overnight.
Mixing bowl – helps you combine ingredients evenly without a mess.
Whisk or spoon – great for stirring the oats and chia seeds until smooth.
Measuring cups and spoons – keep your portions right for the best texture and flavor.

Flavor Variations & Add-Ins

Use almond or coconut milk instead of dairy for a nutty, dairy-free twist.
Add a handful of cocoa nibs or dark chocolate chips for extra chocolate flavor and crunch.
Mix in a splash of almond or hazelnut extract to give a nutty aroma that pairs well with coffee.
Top with fresh raspberries or sliced strawberries for a fruity contrast and pop of color.

How to Make Tiramisu Overnight Oats?

Ingredients You’ll Need:

For the Oat Mixture:

½ cup rolled oats
1 tbsp chia seeds
½ cup milk (dairy or non-dairy)
¼ cup Greek yogurt or mascarpone cheese
1 tbsp maple syrup or honey
1 tsp vanilla extract

For the Coffee Layer:

¼ cup strong brewed coffee or espresso, cooled
1 tbsp cocoa powder, plus extra for dusting
1 tbsp coffee liqueur (optional)

For Garnish:

A few coffee beans or chocolate chips

How Much Time Will You Need?

This recipe only takes about 10 minutes to prepare. However, you will need to refrigerate it overnight or for at least 6 hours so the oats and chia seeds can absorb the flavors and soften perfectly.

Step-by-Step Instructions:

1. Mixing the Oat Base:

In a bowl, stir together the rolled oats, chia seeds, milk, Greek yogurt or mascarpone, maple syrup, and vanilla extract. Mix everything well until combined.

2. Layering the Coffee Mixture:

Split the oat mixture in half. Put one half into a jar or container. Then, in a small bowl, mix the brewed coffee, cocoa powder, and coffee liqueur if you’re using it. Pour this coffee-cocoa mixture over the oat layer in your jar.

3. Adding the Top Layer and Chilling:

Carefully spread the remaining oat mixture over the coffee layer, making a nice even top. Cover your jar and refrigerate overnight or for at least 6 hours so the oats can soak up all the delicious flavors.

4. Finishing Touches:

Before enjoying, dust the top with a little extra cocoa powder and sprinkle on some coffee beans or chocolate chips for a tasty garnish. Serve chilled and enjoy the creamy coffee-flavored goodness!

Can I Use Instant Oats Instead of Rolled Oats?

Yes, you can! Instant oats will absorb liquid faster and create a softer texture, so you might want to reduce the soaking time to 4-6 hours to avoid them becoming too mushy.

How Do I Store Leftover Tiramisu Overnight Oats?

Keep leftovers in an airtight container in the fridge for up to 3 days. Stir before eating, and enjoy cold or at room temperature.

Can I Make This Recipe Dairy-Free?

Absolutely! Use almond, oat, or coconut milk and swap the Greek yogurt or mascarpone for a dairy-free yogurt alternative. The flavor will still be rich and delicious.

Is It Okay to Skip the Coffee Liqueur?

Yes! The coffee liqueur adds a nice touch but isn’t required. Just omit it or replace with a splash of vanilla extract if you prefer.
