No-Bake Oreo Fudge Mocha Tiramisu Box Tips, FAQ & printable recipe

Tips for success

For the best results, use full-fat mascarpone and heavy cream—they whip up into a stable, luxurious mousse. If you're in a hurry, you can chill the dessert for just 2 hours, but 4 hours or overnight gives the best texture.

When dipping the cookies, work in batches to avoid them sitting in the coffee too long. If you want a stronger coffee flavor, you can add a tablespoon of coffee liqueur to the espresso, but this is optional.

To get clean slices, use a sharp knife and wipe it between cuts. For a more decorative presentation, pipe the mousse into the dish in layers using a piping bag. You can also add a drizzle of melted chocolate on top before serving.

If you prefer a less sweet dessert, reduce the powdered sugar to 60 grams. The tiramisu can be made a day ahead and kept in the refrigerator, making it perfect for entertaining.

Variations

• Mocha Nut Tiramisu: Add a layer of toasted chopped hazelnuts or almonds between the mousse and cookies for extra crunch. Toast the nuts in a dry pan over medium heat for 3-4 minutes until fragrant, then let cool before using.
• Peppermint Chocolate Tiramisu: Add 1/2 teaspoon of peppermint extract to the mascarpone mousse and crush peppermint candies over the top instead of Oreo crumbs. This festive twist is perfect for the holidays.
• Caramel Drizzle Tiramisu: Drizzle salted caramel sauce over each layer of mousse and on top before adding the cocoa. The caramel adds a sweet and salty contrast to the bitter coffee and dark chocolate.
• Berry Tiramisu: Add a layer of fresh raspberries or sliced strawberries over the ladyfingers before spreading the mousse. The tartness of the berries cuts through the richness of the chocolate and coffee.

Storage and make-ahead

Fridge

Keep refrigerated in an airtight container for up to 3 days. The texture is best within the first 2 days.

Freezer

Freeze for up to 2 months. Thaw in the refrigerator overnight before serving. The texture may soften slightly.

Reheat

No reheating needed—serve cold. If frozen, thaw in the refrigerator overnight.

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The tiramisu is best enjoyed within 2 days, as the cookies will continue to soften. Keep it covered to prevent it from absorbing other odors in the fridge. Before serving leftovers, let them sit at room temperature for 5-10 minutes to soften slightly.

This tiramisu is an excellent make-ahead dessert. Assemble it up to 24 hours in advance and keep it refrigerated. The chilling time allows the flavors to meld and the texture to set perfectly. If making ahead, wait to dust with cocoa and crushed Oreos until just before serving to prevent them from becoming soggy.

Serving ideas

Serve the tiramisu chilled, straight from the refrigerator, for the best texture. Use a large spoon to scoop out generous portions, ensuring each serving includes all layers.

The dessert pairs beautifully with a cup of espresso or a glass of cold milk. For a special occasion, you can serve it in individual glasses or jars for a portable, elegant presentation.

This tiramisu is rich and satisfying, so a little goes a long way. It's perfect for parties, potlucks, or a weekend treat.

The combination of coffee and chocolate makes it a crowd-pleaser, and the no-bake aspect means you can spend more time with your guests and less time in the kitchen. Enjoy it as a finale to a dinner party or as a midday indulgence.

No-Bake Oreo Fudge Mocha Tiramisu Box

Prep 25 minCook 0 minRest 4 hTotal 4 h 25 minServes 9

Ingredients

• 450 g mascarpone cheese
• 150 g dark chocolate, melted
• 80 g powdered sugar
• 250 ml cold heavy cream
• 24 ladyfingers
• 20 Oreo cookies
• 1 1/2 cups strong brewed espresso or coffee, cooled
• 2 tbsp unsweetened cocoa powder
• 1/2 cup crushed Oreo crumbs

Instructions

1. In a large mixing bowl, combine the mascarpone cheese, melted dark chocolate, and powdered sugar. Beat with an electric mixer on medium speed until smooth and creamy. Gradually pour in the cold heavy cream while continuing to beat. Increase the speed to high and whip until stiff peaks form and the mixture is light and fluffy. Be careful not to overbeat, as the mixture can curdle. The mousse should hold its shape when the whisk is lifted.
2. Pour the cooled espresso or strong coffee into a shallow dish. The dish should be wide enough to dip the ladyfingers and Oreos easily. Set aside.
3. Working one at a time, dip each ladyfinger into the espresso for about 1 second per side. The ladyfinger should be moistened but not soaked through. Similarly, dip each Oreo cookie into the espresso for about 1 second per side. The Oreos should absorb some coffee but remain intact. Place the dipped cookies on a plate as you go.
4. Spread a thin layer of the chocolate mascarpone mousse on the bottom of a 9x9-inch baking dish or acrylic box. Arrange a layer of dipped ladyfingers side by side to cover the bottom. Spread half of the remaining mousse over the ladyfingers, smoothing it into an even layer. Top with a layer of dipped Oreo cookies, then spread the remaining mousse over the Oreos. Smooth the top with a spatula.
5. Cover the dish with plastic wrap or a lid and refrigerate for at least 4 hours, or overnight, until the tiramisu is set and the flavors have melded. The chilling time allows the cookies to soften and the mousse to firm up, making it easy to slice and serve.
6. Before serving, dust the top generously with unsweetened cocoa powder using a fine-mesh sieve. Sprinkle the crushed Oreo crumbs evenly over the cocoa. To serve, scoop out portions with a large spoon, ensuring each serving includes all layers. The tiramisu can be served directly from the dish.
