Given the popularity of tiramisu in the U.S., we’re surprised we haven’t come across a frozen pumpkin tiramisu before this one.
Instead of layering the ingredients in a bowl or pan, this recipe takes the extra step of building it in a springform pan, so it emerges looking like a frozen soufflé.
The recipe is courtesy Pumpkin It Up, a book with scores of delicious pumpkin recipes.
RECIPE: FROZEN PUMPKIN TIRAMISU
Ingredients For 8 Servings
1-1/2 cups heavy whipping cream, chilled
3/4 cup sugar

1 can (15 ounces or 1-7/8 cups) pumpkin purée
3/4 teaspoon pumpkin pie spice
2 packages (3 ounces each) ladyfingers, halved
4 tablespoons apple cider, divided
4 gingersnap cookies, finely crushed
1. BEAT the cream and sugar in a large bowl until stiff peaks form. Add the mascarpone, pumpkin and pumpkin pie spice. Beat just until the filling is smooth.
2. LINE the bottom of a 9 x 2-3/4″ springform pan with 1 package of ladyfingers, breaking and overlapping them to fit. Sprinkle with 2 tablespoons of apple cider.
4. SPREAD half the pumpkin filling over the ladyfingers. Repeat a second layer with the remaining package of ladyfingers, 2 tablespoons of apple cider and the remaining filling. Smooth the top of the tiramisu, cover amnd freeze for at least 4 hours or overnight.
5. UNMOLD: Run a knife around the inside of the pan. Release the pan sides and sprinkle the top with crushed gingersnaps.
THE HISTORY OF TIRAMISU
Tiramisu means “pick me up,” a reference to the caffeine from the espresso liqueur and the energy from the eggs and sugar.
While there are many variations of the recipe, tiramisu is typically composed of layers of sponge cake or ladyfingers, soaked in espresso liqueur, coffee syrup or marsala, and layered with a mascarpone cheese and custard mixture. It is dusted with cocoa or shaved chocolate.
For what is a classic Italian dessert, tiramisu is a relatively recent creation. The origins of the dessert are highly contested, but a strong claim has been made that the recipe was invented in the 1960s at the restaurant, Alle Beccherie in Treviso, Italy by pastry chef Loly Linguanotto.

The restaurant’s matriarch, Alba Campeol, got the idea for the dessert after the birth of one of her children. Weak in bed, she was brought a zabaglione spiked with coffee, to give her energy. When she returned to work, she and her pastry chef worked on the “pick me up” layered dessert.
The original Becchiere recipe did not contain alcohol because it was served to children as well as adults. Today, a good tiramisu is redolent of liqueur or marsala.
