Pumpkin Spice Latte Tiramisu Recipe: A Make-Ahead Guide

This pumpkin spice latte tiramisu recipe keeps the coffee-soaked, cream-layered structure of classic tiramisu, then folds pumpkin purée and pumpkin pie spice into the mascarpone filling. The traditional Marsala soak gets swapped for strong coffee, coffee liqueur, and vanilla. It's a fall variation built on the same technique as the original, not a replacement for it, according to Serious Eats' pumpkin spice latte tiramisu recipe.

This dessert needs real lead time, and that's what makes it useful for a fall gathering. Build it the evening before, and it's already set and sliceable by the time guests arrive. This guide walks through the shopping list, the filling and soak, the layering process, and the chill schedule for this no-bake pumpkin spice latte dessert, the kind you assemble once and leave alone until it's time to serve.

Recipe at a glance

Prep time: about 30 minutes
Chill time: at least 8 hours
Total time: about 8 hours 30 minutes
Yield: 12 servings
Pan: 9-by-13-inch baking dish
Storage: refrigerate up to 3 days, serve cold

These numbers come straight from the published recipe, so use them to work backward from serving time when planning the assembly night.

Plan your PSL tiramisu timeline

Because this dessert needs at least eight hours to chill and holds well refrigerated for up to three days, assemble it the night before serving rather than the morning of. Serving Saturday evening means assembling Friday night, well within the recipe's three-day refrigeration window with room to spare.

Before shopping, settle a couple of questions with whoever's coming. The soak includes six tablespoons of coffee liqueur, and the filling contains six egg yolks. This guide follows the recipe as published. If anyone on the guest list avoids alcohol or has questions about egg preparation, review the full recipe method before serving it to them, or plan a different dessert built around those constraints from the start rather than adjusting this one on the fly.

Decide on serving size before you shop, too. This recipe is scaled for a 9-by-13-inch pan and 12 servings. For a smaller gathering, look for a tested half-batch version rather than estimating; halving a mascarpone-and-cream filling by eye is where texture problems tend to start.

Ingredients for this pumpkin spice latte tiramisu recipe

For the coffee soak:

2 cups strong brewed coffee (espresso, Moka pot coffee, or coffee concentrate all work)
6 tablespoons coffee liqueur
1½ teaspoons vanilla extract

For the pumpkin-mascarpone filling:

6 large egg yolks
⅔ cup granulated sugar
¼ teaspoon kosher salt
2 cups cold mascarpone cheese
1 cup pumpkin purée
1½ teaspoons pumpkin pie spice
1 cup heavy cream

For assembly and topping:

48 ladyfingers
2 teaspoons ground cinnamon
1 teaspoon espresso powder

One shopping distinction is worth making at the store: buy plain pumpkin purée, not sweetened pumpkin pie filling. The sugar and spice in this recipe are measured separately, so a pre-sweetened, pre-spiced pie filling would throw off both the sweetness level and the texture of the base.

For equipment, plan on a 9-by-13-inch baking dish, since that's the pan size the recipe is built around. A hand or stand mixer for whipping the cream, a shallow dish for dipping ladyfingers, and a fine-mesh sieve for the topping all make the process easier, though none of that is a strict requirement, just a practical starting point. Swap in whatever's already in the kitchen where it makes sense.

Before you start: a quick kitchen check

A few minutes of setup before mixing anything saves scrambling later:

Clear a flat shelf in the refrigerator large enough for a 9-by-13-inch dish to sit level for at least eight hours.
Brew the coffee ahead so it has time to cool before the ladyfingers go in. Warm coffee softens biscuits faster than the two-to-three-second dip time accounts for.
Take the mascarpone out of the refrigerator only right before mixing. The recipe calls for it cold, and softened mascarpone is harder to fold smoothly.
Set out a shallow dish for dipping, wide enough to rotate a ladyfinger without breaking it, right next to the baking dish so soaked biscuits go straight in.

How to make the pumpkin-mascarpone filling

The filling comes together in two parts that get combined at the end. First, the base: egg yolks, sugar, salt, cold mascarpone, pumpkin purée, and pumpkin pie spice mix into one smooth mixture. Second, the lightener: heavy cream gets whipped on its own until it holds its shape, then folded into that base.

That folding step is what makes the finished filling taste light instead of dense. The airy texture comes from the whipped cream folded into the mascarpone mixture, not from the mascarpone or pumpkin base on its own, per the recipe. Fold with a spatula, cutting down through the center and turning the bowl, rather than stirring in circles. Stirring knocks the air back out of the cream you just whipped in.

This mirrors a broader pastry principle: lightening a rich, custard-style base with whipped cream produces an airier result the more whipped cream gets folded in, according to King Arthur Baking's explanation of diplomat cream. That comparison comes from a cooked pastry-cream filling, a different base than the one used here, so treat it as a useful way to understand why folding matters, not as a substitute for this tiramisu's own method.

How to layer coffee-soaked ladyfingers for pumpkin tiramisu

Stir the coffee, coffee liqueur, and vanilla extract together in a shallow dish. This mixture stands in for tiramisu's traditional Marsala soak, replacing that component with a coffee-based one rather than removing alcohol from the dessert altogether, since coffee liqueur itself contains alcohol.

Dip each ladyfinger into the coffee mixture for two to three seconds, rotating so both sides get coated, and never let a biscuit sit submerged. The recipe is explicit on both points: no submerging, and no more than three seconds per biscuit.

Dip 24 ladyfingers into the coffee mixture, rotating to coat, then transfer each one straight to a 9-by-13-inch baking dish.
Arrange them in a single layer, trimming or breaking pieces to fit the corners neatly.
Spread half the mascarpone filling, about 3½ cups, evenly over the ladyfingers.
Repeat with the remaining 24 ladyfingers and the rest of the filling, smoothing the top layer flat with a spatula.

Work in small batches so the dip timing stays consistent across all 48 pieces, and keep the baking dish within reach so each soaked ladyfinger goes in right away instead of sitting on the counter.

Chill, store, and serve your pumpkin spice tiramisu

Whisk the ground cinnamon and espresso powder together, then dust the top of the dessert through a fine-mesh sieve for even, light coverage. Cover it loosely with plastic wrap and refrigerate for at least eight hours, up to three days.

Serve it cold, straight from the fridge. It isn't meant to sit out and come to room temperature first. That chill window does more than firm things up: it's also what allows the ladyfingers to soften fully, so give it the full eight hours if the schedule allows.

Each serving runs about 574 calories and 46 grams of fat, per the recipe's nutrition figures. That's useful context when portioning for a larger gathering, especially if the tiramisu is following a full dinner rather than standing on its own.

What to check before you serve

If a batch turns out mushy at the ladyfinger layer rather than tender, the dip likely ran long. That's a note for next time, since there's no fixing the texture once the biscuits have already absorbed the coffee mixture.

Make this version when the coffee liqueur and eggs work for the guest list at hand. When they don't, choose a separately tested recipe built around those constraints instead of substituting ingredients on assembly day. The ratios here were tested as written, and a make-ahead dessert built on dairy and eggs isn't the place to improvise.
