Protein Tiramisu Recipe with a Creamy Greek Yogurt Filling

Protein tiramisu is an Italian-inspired chilled dessert made with espresso-dipped ladyfingers and a creamy filling of Greek yogurt, mascarpone, and protein powder. It keeps the familiar coffee-and-cocoa flavors while using a simple, egg-free filling that can be assembled ahead and served cold.

Ingredients

1 1/2 cups (360 ml) cold, strong espresso or very strong coffee
24 crisp ladyfingers (about 7 oz / 200 g)
1 cup (225 g) cold mascarpone cheese
1 1/2 cups (360 g) plain Greek yogurt, preferably whole-milk and thick
1 scoop (30 g) vanilla or unflavored protein powder
1/3 cup (40 g) powdered sugar
1 teaspoon (5 ml) vanilla extract
1/8 teaspoon (about 0.3 g) fine salt
2 tablespoons (10 g) unsweetened cocoa powder, for finishing

Instructions

Set out an 8-inch square (20 cm square) baking dish and make sure the espresso is completely cold. If you are brewing coffee for the recipe, prepare it in advance and chill it; warm coffee softens the ladyfingers too quickly and can loosen the filling. A shallow bowl makes dipping easier than pouring the espresso directly over the biscuits.
Put the cold mascarpone in a medium mixing bowl and stir it briefly with a spatula until smooth and pliable. Add the Greek yogurt, powdered sugar, vanilla, and salt. Fold and stir gently until no streaks of mascarpone remain. Avoid beating for a long time: mascarpone can become grainy if it is overworked, and a little gentle mixing is all this filling needs.
Sift the protein powder into the bowl in two additions, stirring well after each one. Adding it gradually helps prevent dry pockets and clumps. The finished mixture should be thick, spoonable, and smooth. If your powder is strongly sweetened, taste the filling before adding anything extra; the measured powdered sugar is a starting point, and different protein powders vary in sweetness.
Pour the cold espresso into a shallow bowl. Dip each ladyfinger for about one second per side, just long enough to moisten the surface, then arrange it in a single layer in the dish. Crisp savoiardi absorb liquid quickly, so do not leave them soaking in the coffee. If a biscuit seems dry in the center, a slightly longer dip is safer than letting it sit in the bowl.
Spread half of the filling evenly over the first layer of ladyfingers, taking the mixture right to the corners. Dip the remaining ladyfingers in the espresso and arrange them in a second layer. If the biscuits need to be broken to fit, make the pieces fit snugly rather than stacking them; an even layer gives each serving a consistent amount of coffee and cream.
Spoon the rest of the filling over the second layer and smooth the top with an offset spatula or the back of a spoon. Cover the dish without letting the wrap touch the surface, then refrigerate for at least 6 hours. This time lets the filling firm up and the coffee flavor settle into the biscuits. For the neatest slices, chill it overnight.
Just before serving, sift the cocoa powder evenly over the top. Use a fine-mesh sieve to avoid heavy patches of cocoa. Cut into eight portions with a clean knife, wiping the blade between cuts if you want tidy edges, and serve the tiramisu cold.

Tips

Use thick yogurt. Greek yogurt works best because it contains less free liquid than regular yogurt. If yours looks loose or watery, drain it in a fine-mesh strainer lined with a coffee filter or clean cheesecloth in the refrigerator for 30 to 60 minutes. A thinner yogurt can make the filling soft and cause liquid to collect at the bottom.
Dip quickly rather than soaking. Ladyfingers should be damp, not saturated. A long soak makes them fragile and can turn the bottom of the dessert mushy before the filling has time to set. Keep the coffee cold, dip one biscuit at a time, and move it directly into the dish.
Choose a protein powder you like the taste of. Vanilla gives the cream a gentle dessert flavor; unflavored powder leaves the coffee and cocoa more prominent. Whey, casein, and plant-based powders absorb liquid differently, so the filling may be thicker with one type than another. If it turns unusually stiff, fold in Greek yogurt one tablespoon at a time until it is spreadable.
Keep the mascarpone cool and mix gently. Cold mascarpone is less likely to become loose while mixing. If it is so firm that it will not blend, let it stand at room temperature for about 5 minutes, then stir just until smooth. Do not try to fix a grainy mixture by beating it aggressively; that can make the texture worse.

Serving Suggestions

Serve the tiramisu straight from the refrigerator, when its layers are firm and the coffee flavor is clear. A small square is a satisfying dessert portion because the mascarpone filling and espresso-soaked biscuits are rich. If the dessert has been chilled overnight, let it sit on the counter for about 5 minutes before cutting; it will still be cold, but the knife will pass through the layers more easily.

For a simple finish, add the cocoa just before bringing the dish to the table so it stays dry and aromatic. A few dark-chocolate shavings or a light dusting of finely grated chocolate can go on top alongside the cocoa. Serve with fresh berries or sliced strawberries if you want something bright and tart beside the creamy layers. Coffee, decaf espresso, or a glass of cold milk makes an easy nonalcoholic pairing.

Variations

Make it without mascarpone: Replace the cup of mascarpone with 1 cup (225 g) additional thick Greek yogurt and add 1 tablespoon (15 ml) of neutral-tasting cream or milk if the mixture is too firm. The result will be tangier and less rich than the version made with mascarpone, so taste the filling and adjust the powdered sugar slightly if needed.

Try a chocolate-coffee version: Whisk 1 tablespoon (5 g) unsweetened cocoa powder into the cold espresso before dipping the biscuits. This makes the coffee layer more chocolate-forward without changing the assembly. Keep the cocoa topping as written, or use chocolate shavings for a less bitter finish.

Use a different protein flavor: Chocolate protein powder can replace the vanilla or unflavored powder for a deeper cocoa taste. Start with the same 30 g amount, then check the filling before adding any extra sweetener. A plant-based powder is also an option, though it may absorb more moisture and make the filling firmer; loosen it gradually with extra yogurt rather than pouring in a lot of liquid at once.

Make individual portions: Layer the dipped ladyfingers and filling in eight small glasses or jars instead of one dish. Break the biscuits to fit, keeping the same two biscuit layers and two filling layers. Individual portions are convenient for serving, but cover them well and chill for the same minimum of 6 hours so the biscuits soften evenly.

Storage and Reheating

Cover the tiramisu and refrigerate it within 2 hours of assembly or serving. Keep it chilled at 40°F (4°C) or below and eat it within 3 to 4 days. The cocoa topping may darken or absorb moisture as it sits, so for the best appearance, dust each portion shortly before serving. Use a clean utensil each time you serve from the dish, and return leftovers to the refrigerator promptly.

This dessert is not meant to be reheated. Freezing is possible, although it can change the texture of the yogurt filling and make it slightly less smooth after thawing. For best quality, freeze covered portions for up to 1 month, thaw them overnight in the refrigerator, and add fresh cocoa after thawing. Do not thaw it on the counter, and do not refreeze portions that have already thawed.

Frequently Asked Questions

Does protein tiramisu taste like regular tiramisu?

It has the same main cues—coffee-soaked ladyfingers, creamy layers, and cocoa on top—but the filling is tangier and somewhat lighter-tasting because it includes Greek yogurt and protein powder. Mascarpone keeps it rich, while the long chill softens the biscuits and brings the layers together. The exact flavor depends on the protein powder, so choose one whose taste you enjoy on its own.

Can I make it the day before serving?

Yes. Making it the day before is convenient, and an overnight chill gives the filling plenty of time to firm while the ladyfingers take on the espresso. Cover the dish tightly and wait to dust on the cocoa until just before serving. The finished dessert keeps refrigerated for 3 to 4 days, though the biscuits gradually become softer over time.

Why is my filling runny?

The most common causes are thin yogurt, mascarpone that became too warm, or a protein powder that did not thicken the mixture as expected. Use thick Greek yogurt and cold mascarpone, then mix only until combined. If the filling is already loose, chill it for 20 to 30 minutes before layering; if it still seems too soft, stir in a small amount of protein powder, a teaspoon at a time, rather than adding a large scoop all at once.

Can I use regular coffee instead of espresso?

Yes. Brew regular coffee stronger than you would for drinking, then cool it completely before dipping the ladyfingers. Espresso gives a concentrated flavor in a small volume, but strong brewed coffee works well and is easier to prepare in some kitchens. Avoid weak coffee, which can make the dessert taste muted, and do not add extra liquid to compensate.

Can I make this recipe gluten-free?

You can use gluten-free ladyfingers if you can find them, checking the package because availability and texture vary. Dip them very briefly at first; some gluten-free biscuits soften faster than standard savoiardi. The rest of the ingredients are commonly gluten-free, but check the labels on the protein powder, cocoa, and other packaged ingredients if you need to avoid gluten carefully.
