This no-bake dessert pairs soft ladyfingers with a fluffy eggnog mascarpone filling. A little bourbon adds warmth to the dipping mixture. Swirled whipped cream and a light dusting of cinnamon and nutmeg finish the top. Make it ahead so the layers have time to soften.

How to Make Eggnog Tiramisu
Keep the cream cold and fold gently to preserve its airy texture.
Step 1: Mix the Mascarpone Base
Stir 8 ounces softened mascarpone, 1/4 teaspoon ground nutmeg, 1/4 teaspoon ground cinnamon, 1/8 teaspoon table salt and 1/4 cup refrigerated eggnog in a large bowl just until combined. Set aside.

Step 2: Whip the Cream
Beat 2 cups cold heavy whipping cream and 1/2 cup powdered sugar in a stand mixer with its whisk attachment on medium speed for about 3 minutes, until medium-stiff peaks form.

Step 3: Fold the Filling
Gradually fold 3 cups of the whipped cream mixture into the mascarpone base just until combined. Reserve the remaining whipped cream, about 1 cup, for topping.

Step 4: Dip the First Layer
Whisk 2 1/2 tablespoons bourbon and the remaining 1 cup refrigerated eggnog in a wide, shallow bowl.
Dunk and roll 12 ladyfingers one at a time for about 6 seconds each, just until they start to soften. Fit them in one even layer in an unlined white 8-inch square baking dish with two built-in side handles, breaking them as needed.

Step 5: Build the Second Layer
Spread half the mascarpone filling, about 2 cups, over the first biscuit layer.
Dip the remaining 12 ladyfingers in the same eggnog-bourbon mixture for about 6 seconds each, and arrange them over the filling. Spread the remaining mascarpone filling, about 2 cups, evenly over the second biscuit layer. Discard leftover dipping mixture.

Step 6: Top and Chill
Spread the reserved 1 cup whipped cream over the filling, making soft swirls.
Loosely cover and refrigerate for at least 8 hours or up to 24 hours, until the ladyfingers are soft.

Step 7: Garnish and Serve
Uncover just before serving. Lightly dust with additional ground cinnamon and nutmeg, as desired.
Cut into 9 servings and lift each portion onto a plate. Serve the dessert by itself.

Why This Recipe Works (Quick Science)
Mascarpone gives the filling body, while whipped cream adds air. A brief eggnog-bourbon soak starts to soften the biscuits. During the long chill, moisture moves through each layer so the dessert becomes tender and scoopable.

Common Mistakes to Avoid
- Overmixing mascarpone: Stop as soon as the base is combined.
- Overwhipping cream: Stop at medium-stiff peaks, before it turns grainy.
- Soaking biscuits too long: About 6 seconds per biscuit is enough to begin softening them.
- Skipping the chill: Give the dessert at least 8 hours.
Make-Ahead Tips
Assemble and chill for 8 to 24 hours. Add the cinnamon and nutmeg just before serving.
