Tiramisu

Tiramisu CakeOne of Fabio’s favorite desserts is Tiramisu, and so this year for Fabio’s birthday cake I decided to make this Cake version of a Tiramisu for him.  The design is based on a cake I saw on the Williams Sonoma website which seemed to use a sponge cake in the place of the traditional savoiardi layer. 

Using a sponge cake instead of the lady fingers provided both a stable base to hold up the layers of Rum infused Marscapone cream as well as hold up to a generous brushing of Espresso and rum as it was assembled.

The recipe for the sponge cake portion is adapted from the cookbook Tartine (the pastry focussed companion book to Tartine Bread which I have written about previously) and the filling I adapted from a recipe my aunt shared with me from America’s test kitchen.  the Original recipe makes the perfect classic tiramisu and as a result is the only recipe I can imagine using when attempting this dessert.  

Feel free to play around with the proportion and type of alcohol used.  As it is written, this will make a boozy dessert (as it should be), but you can scale back on the rum, or use a milder liqueuer like Kahlua instead if that suits you.  We have used a combination of dark rum and Kahlua in the past when making the regular Tiramisu with great success.

Instructions / Instrucciones

Sponge cake / Torta o Pastel

  • In a saucepan, melt the butter over low heat and once liquid, remove from the heat and keep warm  / En un recipiente derretir la mantequilla en fuego lento, sacar del fuego cuando este líquido, dejar a un lado y mantener caliente.
  • Sift the flour and cornstarch together and set aside / Colar juntos la azúcar  y la maicena y dejar a un lado.

  • Mix together the eggs, salt and sugar, in the stainless steel bowl of a stand mixer / Mezclar los huevos, sal y azúcar en un recipiente de acero.
  • Place mixing bowl over simmering water, and whisk continuously for about 5-7 minutes, until the mixture is hot to the touch (120 F on a thermometer) / Poner el recipiente de acero encima de la olla con agua y empieza a batir la mezcla por  5-7 minutos , hasta que la mezcla este caliente (120 F de temperatura en un termómetro)
  • Lock the mixing bowl into the stand mixer and whisk on medium high speed until the batter is pale yellow, has tripled in volume.  When you life the whisk out of the mixture, the batter should fall in a wide ribbon that falls back on itself and dissolves slowly into the rest of the batter (This will take about 5 minutes) / Colocar la mezcla a una batidora de pie, en velocidad media alta empieza a batir la mezcla hasta que este de color pálido amarillo y el volumen de la mezcla haya crecido.

  • Fold the flour mixture into the batter in three additions, make sure to use the spatula to mix all the way to the bottom of the bowl, as this is where the flour will fall to /  Colocar la mezcla de harina gentilmente mezclando bien hasta que todo este incorporado.
  • Remove a spoon full of the batter to a small bowl and whisk in the warm melted butter, then add the batter/butter back to the rest and fold to incorporate / Colocar una cucharada de la mezcla en un recipiente pequeño y agregar la mantequilla derretida y mezlcar, luego incorporar esto a la mezcla.
  • Pour the batter into the prepared pan.  As this recipe is designed for a 10 inch cake – if you are using a 9 inch pan (like we did) pour the batter without scraping the sides with a spatula into the bowl.  The batter left in the bowl can be added to a muffin tin to bake some mini sponge cakes for another use  / Vertir la mezcla en el molde preparado. En esta receta se ha diseñado para una torta de 10 pulgadas – si estás usando un molde de 9 pulgadas (como hicimos nosotros) vierta la mezcla sin raspar los lados con una espátula en el recipiente. La masa que queda en el recipiente se puede agregar a un molde para muffins para hornear o para otro uso.

  • Without washing the bowl, add whipping cream and whisk at medium high until the cream holds stiff peaks  / Sin lavar el recipiente agregar crema de leche y batir hasta que esté en punto de nieve.
  • Fold 1/3 of the whipped cream into the marscapone to lighten, the fold in the rest of the cream until no white streaks remain / Agregar gentilmente la crema de leche en la mezcla de queso marscapone y huevos, mezclando suavemente hasta que todo esté incorporado.

Assembly / Montaje

  • Slice the sponge in half and place the top half upside down back into the springform pan (the cut side should be facing up) / Partir o rebanar en la mitad la torta o pastel y colocarla otra vez en el molde. (ver foto)
  • Brush the cake with the espresso/rum mixture, evenly covering the whole surface / Colocar en la torta la mezcla de  espresso/ron cubriendo toda la superficie.
  • Add half of the marscapone/cream mixture and spread evenly with an offset spatula / Agregar la mitad de la mezcla de marscaponesobre la superficie  (ver foto)

Assembling the Tiramisu

  • Sift an even layer of cocoa over the marscapone cream and top with the other half of the cake (cut side down – the bottom of the baked cake should now be the top) / Colocar la cocoa (colada) encima de la crema de masrcapone y agregar la otra mitad de la torta o pastel.
