This creamy pumpkin tiramisu layers coffee-soaked ladyfingers with a fluffy pumpkin spice mascarpone cream and a generous dusting of cocoa powder. It is a no-bake fall dessert ready in 25 minutes of prep!
Brew the Coffee: Brew the espresso or strong coffee and let it cool while you make the cream.
Mix the Base: In a large mixing bowl, beat the mascarpone, brown sugar, granulated sugar, salt, and pumpkin pie spice with an electric hand mixer until well combined.
Add the Pumpkin: Add the pumpkin puree and vanilla extract and mix until smooth.
Whip: Add the cold heavy cream and beat for 3 to 4 minutes, until the filling is thick and fluffy.
Assemble the tiramisu
First Layer: Dip each ladyfinger into the cooled coffee for just 1 to 2 seconds and arrange them in an even layer in a 9x13-inch dish.
Cream and Second Layer: Spread half of the pumpkin cream over the ladyfingers and smooth it with a spatula. Top with another layer of dipped ladyfingers.
Pipe: Transfer the remaining cream to a piping bag fitted with a star tip and pipe dollops all over the top.
Chill: Cover with plastic wrap and refrigerate for at least 4 hours, or overnight, so the ladyfingers soften.
Dust and Serve: Just before serving, generously dust the top with cocoa powder.
Notes
Quick Dip: Dip the ladyfingers for only 1 to 2 seconds so they don't turn soggy.
Cool the Coffee: Use cooled coffee so the ladyfingers hold their shape.
Cold Dairy: Use cold mascarpone and heavy cream so the filling whips up thick and fluffy.
Pumpkin Puree: Use plain pumpkin puree, not pumpkin pie filling, which has added sugar and spices.
Chill Time: Chill for at least 4 hours, or overnight for the best texture.
Cocoa Last: Dust with cocoa powder right before serving.
Storage: Keep covered in the fridge for up to 4 days.
