Tiramisu Protein Overnight Oats

Creamy tiramisu overnight oats with 29g of protein per serving. Espresso-soaked oats topped with a white chocolate Greek yogurt “mascarpone” layer and a dusting of cocoa — dessert for breakfast that hits your macros.

Tiramisu protein overnight oats are a no-cook breakfast made by mixing oats, chia seeds, protein powder, almond milk, and 2 shots of espresso, then topping with a white chocolate–Greek yogurt–espresso ganache and a dusting of cocoa powder. One serving packs 29g of protein and 468 calories — it tastes like a tiramisu cup with the macros of a protein shake.

The espresso in both the oats AND the ganache is what makes this read as real tiramisu instead of just coffee-flavored oats. The white chocolate yogurt topping mimics the mascarpone layer, and a sift of cocoa powder right before eating completes the look.

Why You’ll Love This Recipe

• 29g of protein per serving from Greek yogurt + protein powder

• Make-ahead friendly — prep the night before, grab and go in the morning
• Naturally gluten-free with certified gluten-free oats

Ingredients You’ll Need

(Full measurements in the recipe card at the bottom of the post.)

For the oats:

• Old-fashioned rolled oats — best texture for overnight oats. Quick oats work but go softer. Steel-cut won’t soften without cooking. Use certified gluten-free if needed.
• Unsweetened almond milk — neutral flavor. Oat, cashew, coconut, or regular milk all work.
• Chia seeds — absorb liquid and thicken the oats overnight. Flax seeds work as a 1:1 swap.
• Vanilla protein powder — I use PEScience Gourmet Vanilla (code BAILEY saves you). Mocha-flavored protein powder works beautifully here and pushes the coffee flavor (a reader-tested swap).
• Espresso — 2 shots in the oats. If you don’t have espresso, ¼ cup of strong brewed coffee works. Espresso powder works in a pinch. Decaf works if you’re avoiding caffeine.

“Mascarpone” topping:

• White chocolate chips — melted in 30-second intervals. Use vegan brand for dairy-free.
• Plain Greek yogurt — pushes the protein up and gives the topping a tangy “mascarpone” feel. Full-fat is creamiest; non-fat is leaner.
• Espresso — 1 tablespoon in the ganache to tie the coffee flavor through both layers.

For finishing:

• Cocoa powder — sifted on top right before eating. This is non-negotiable — it’s the visual and flavor signature of tiramisu.

How to Make Tiramisu Protein Overnight Oats

1. Mix the oat base. Add the oats, chia seeds, protein powder, 2 shots of espresso, and almond milk to a bowl or mason jar. Stir well until the protein powder dissolves.
2. Refrigerate while you prep the topping (about 5 minutes).
3. Make the mascarpone ganache. Microwave the white chocolate chips in 30-second intervals until melted. Whisk in the Greek yogurt and 1 tablespoon of espresso until smooth and lump-free.
4. Layer the topping over the chilled oats. Cover and refrigerate for at least 4 hours, ideally overnight, to fully set.
5. In the morning — sift cocoa powder generously over the top. Eat cold straight from the fridge or warm briefly in the microwave.

Tips for the Best Results

1. Use strong espresso, not weak coffee. Tiramisu is a coffee-forward dessert. Weak coffee = bland oats. Two shots of espresso or ¼ cup of strong brewed coffee is what gives you that real tiramisu flavor.
2. Bring everything to room temperature before mixing the ganache. Cold Greek yogurt + warm white chocolate seizes up into clumps. Let the yogurt sit out for 5-10 minutes first.
3. Don’t skip the cocoa powder on top. This is what makes it tiramisu instead of just coffee oats. Sift it for an even dusting.
4. Sift cocoa right before eating, not the night before. Cocoa absorbs moisture overnight and can turn pasty if sifted too early.
5. Want a stronger coffee flavor? Sub espresso powder (1 tsp dissolved in 2 tablespoons hot water) for a more intense, concentrated coffee note than brewed coffee alone.

Mix-In Variations

• Mocha protein powder swap (reader favorite): Nathalie used Mocha-flavored protein instead of vanilla and called it life-changing. Pushes the coffee flavor harder.
• Extra protein boost: Add 2 tablespoons of cottage cheese to the oat base — pushes protein over 40g per serving with no chalkiness
• Kahlua tiramisu (adults only): Add 1 teaspoon of Kahlua to the ganache for a classic boozy tiramisu note
• Chocolate lover’s tiramisu: Stir 1 tablespoon of cocoa powder into the oat base + add chocolate chips on top
• Lower sugar: Use sugar-free white chocolate chips and skip the maple syrup
• Decaf version: Use decaf espresso or decaf coffee for an evening-friendly version
• Dairy-free: Use coconut yogurt, vegan white chocolate chips, plant-based protein

How to Store and Meal Prep

• Fridge: Store sealed jars for up to 4 days. The flavor actually deepens over time as the espresso flavor sets into the oats.
• Meal prep tip: Make 3-4 jars at once. The espresso oats keep beautifully — just sift fresh cocoa on top right before eating.
• Best containers: Wide-mouth mason jars (16 oz) show the layered look. Small glass dishes work for that authentic tiramisu cup vibe.
• Save the cocoa for the morning — sifting the night before makes it absorb into the topping and lose its texture.
• Don’t freeze — the texture suffers when thawed.
