Ingredients You’ll Need

This recipe uses pantry staples and a few fresh ingredients, perfectly balanced to recreate that delicious tiramisu flavor in a wholesome baked oats form. A quick tip — for the best texture, I like using rolled oats, and if you want the yogurt mousse to really shine, use a thick Greek-style or plant-based yogurt.

Bananas: Mash them ripe for natural sweetness and moisture.
Soy milk: Unsweetened works best to control sweetness; any plant milk is fine too.
Espresso: Freshly brewed or instant coffee works—this is key for that signature tiramisu flavor.
Maple syrup: Adjust sweetness to your taste, I usually stick to this natural sweetener.
Cashew or almond butter: Adds creaminess and richness to both the oats and yogurt layers.
Vanilla extract: Brings warmth and depth to every bite.
Apple cider vinegar or lemon juice: Helps the oats rise and balances flavors.
Rolled oats: Provides structure and that comforting chewiness.
Cocoa powder: For the classic chocolatey undertone, a must-have here.
Vanilla protein powder (optional): Adds fluffiness to the yogurt mousse and boosts protein.
Baking powder and baking soda: Give the baked oats a light texture.
Salt: Just a pinch to enhance all the flavors.
Thick plain yogurt: The star of the mousse topping — Greek-style or thick plant-based yogurt works beautifully.
Maple syrup (optional for topping): Sweeten the mousse to your preference.

Variations

I love making this recipe my own depending on the season or what I have in the fridge. The beauty of the Tiramisu Baked Oats with Yogurt Mousse Recipe is how adaptable it is, so feel free to experiment and make it your own.

Use coconut yogurt: I tried this once and it gave a lovely tropical twist to the mousse, making for a richer flavor.
Swap espresso for chai: For a spiced autumn vibe, swapping coffee for chai tea powder gave it a new warm dimension that my family enjoyed.
Make it gluten-free: Use certified gluten-free oats, and you’re good to go without sacrificing any taste or texture.
Add nuts or chocolate chips: If you want a crunchy pop or a little surprise inside, stirring in chopped nuts or dairy-free chocolate chips before baking is delightful.

How to Make Tiramisu Baked Oats with Yogurt Mousse Recipe

Step 1: Prep Your Baking Dish and Ingredients

Start by preheating your oven to 350°F (180°C) and lightly grease an 8 × 8 or 9 × 9 inch square baking dish. This size helps the oats get that nice, thick height. While the oven warms up, mash your medium-ripe bananas until smooth — I usually use a fork and press them down well so there are no big chunks lurking.

Step 2: Mix the Wet Ingredients

In a large bowl, combine mashed bananas, soy milk, espresso (or your instant coffee mixture), maple syrup, cashew butter, vanilla extract, and apple cider vinegar. I like to blend it until everything looks well incorporated and creamy. You’ll notice the apple cider vinegar helps the mixture thicken a bit once combined with the baking soda later.

Step 3: Combine the Dry Ingredients

In another bowl, whisk together the rolled oats, cocoa powder, optional protein powder, baking powder, baking soda, and salt. This step helps distribute everything evenly so the oats bake uniformly. I usually give the dry mix a quick taste here — yep, oats and cocoa powder combo already smells so comforting.

Step 4: Bring It All Together and Bake

Pour the wet ingredients into the dry and stir until fully combined. The batter will be thick but spreadable. Transfer it into your prepared baking dish and smooth the surface with a spatula. Pop it in the oven and bake for about 35 to 40 minutes until the center feels set and the top turns a beautiful golden brown. A toothpick in the center should come out mostly clean with just a few crumbs clinging.

Step 5: Prepare the Yogurt Mousse

While those oats are baking or cooling, start on the yogurt layer. Warm your cashew or almond butter in the microwave for 10 seconds — this softens it so it mixes easily. Stir in the vanilla extract, then blend in 1 to 2 tablespoons of the yogurt until smooth. Add the rest of the yogurt, a pinch of salt, optional protein powder, and maple syrup if you like it sweeter. Whisk until you get a mousse-like fluffy consistency. I find this step makes all the difference — the protein powder helps add body and fluff.

Step 6: Assemble and Serve

Once the baked oats have completely cooled (patience here is key so the mousse doesn’t melt), spread the yogurt mousse evenly over the top. Just before serving, dust with cocoa powder to get that classic tiramisu finish. The contrast between the warm-once-reheated oats and cool mousse is absolutely divine.

How to Serve Tiramisu Baked Oats with Yogurt Mousse Recipe

The image shows a top view of 15 small white bowls arranged neatly on a surface with a white marbled texture. The largest bowl in the top left is filled with light beige rolled oats, next to it on the right is a smaller bowl with mashed banana, creamy and lumpy with a pale yellow color. Next to the banana on the right is a bowl with a smooth white liquid, possibly a milk or plant-based milk. Below the oats, there is a medium bowl containing a thick, light brown creamy paste, and next to it on the right is a smaller bowl with a thinner beige liquid. Below these, a bowl contains a dark brown rich coffee or espresso liquid with a slight foam ring around the edge. To the right, a medium-sized bowl is filled with a clear brown syrup. Below the thick light brown paste, there is a bowl with cocoa powder, dark brown and powdery. Beside it is a bowl of light beige flour, fine and powdery. Below the coffee, a smaller bowl holds a dark amber liquid, likely vanilla or soy sauce. Next to it, a medium bowl contains golden honey or syrup with a smooth surface. On the bottom left, three tiny bowls contain white powders: baking soda, baking powder, and salt, all fine and powdery. The largest bowl on the bottom right is filled with thick white yogurt or sour cream, smooth and creamy with visible swirls on the surface. The bowls are arranged in a casual grid pattern, creating a neat and organized look. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

I love dusting this with extra cocoa powder for that classic tiramisu look. Sometimes, I sprinkle a few finely chopped dark chocolate shavings or a pinch of espresso powder to pump up the coffee aroma. If you like a bit of crunch, toasted chopped nuts (hazelnuts or almonds) on top work beautifully too.

Side Dishes

Because this recipe is quite filling and rich, I usually keep sides simple. A fresh fruit salad with tangy berries, or even a few slices of ripe pear complement the dish nicely. Sometimes, I serve it with a small cup of black coffee to double down on that coffee flavor.

Creative Ways to Present

For special occasions, I’ve layered the baked oats and yogurt mousse in individual glass jars — it looks elegant and guests love the personal touch. You can also make mini portions by baking the oats in muffin tins and topping each with a dollop of mousse for cute, grab-and-go servings.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge for up to 4 days. Just keep the yogurt mousse separate if you plan to reheat the oats warm later. This way the mousse stays fresh and creamy. When I’ve had leftovers, I find the oats maintain their texture beautifully overnight.

Freezing

I usually freeze the oat base alone if I want to save some for later — it freezes well and you can thaw overnight in the fridge. Avoid freezing the yogurt topping though, as it tends to separate and get watery once thawed.

Reheating

Reheat the baked oats gently in the microwave for 45–60 seconds. Once warmed, add a fresh layer of the yogurt mousse topping. This helps keep the mousse light and prevents any unwanted texture changes from heating.

FAQs

Can I substitute the soy milk with other types of milk in this Tiramisu Baked Oats with Yogurt Mousse Recipe?

Absolutely! While I recommend unsweetened soy milk for a creamy texture and neutral flavor, you can swap it with almond, oat, coconut, or even regular dairy milk. Just keep in mind some milks may alter the flavor slightly or change the baking consistency, so opt for unsweetened to maintain balance.
Is the protein powder in the yogurt layer necessary?

The protein powder is optional but highly recommended if you want the yogurt to have that fluffy mousse-like texture. Without it, the yogurt topping will still taste delicious but be more like regular yogurt rather than a light mousse.
Can I make this gluten-free?

Yes! Simply use certified gluten-free rolled oats. The recipe doesn’t involve any other gluten-containing ingredients, so it’s easy to adapt for gluten-free diets.
How sweet is this Tiramisu Baked Oats with Yogurt Mousse Recipe compared to traditional tiramisu?

This recipe is on the less sweet side to keep it balanced and suitable for breakfast. However, you can always add more maple syrup in the batter or the yogurt mousse if you prefer it sweeter. I usually taste the batter before baking to decide.
