Directions

1. 1
   In a mixing bowl cream butter and sugar, add Mascarpone and continue creaming until very smooth and fluffy. Evenly divide the mixture in two portions. In one portion add orange zest, juice, and candied orange peel (diced small). To the second portion add Instant Espresso powder, Coffee liquor and steer the mixture until very smooth.
2. 2
   Assemble the cake: Cover a large cutting board with parchment paper. Dip each graham cracker in chilled coffee and lay them out in a layer of 3 in width by 6 in length. Spread evenly the first mixture (with orange zest, juice, and candied orange peel), all over the cracker layer. Cover with another layer of graham crackers dipped in chilled coffee. Spread evenly the second mixture (Instant Espresso powder, Coffee liquor).

   Using the parchment paper gather two longer sides of the cake not touching the middle. It should look like a triangle shape log. Transfer the cake on the cutting board to the refrigerator for a few hours until it hardened.

   Make the Mocha Ganache: Bring to a simmer 1/2 cup of strong freshly brewed coffee. Strain thru a fine sift and pour over 8 ounces of bittersweet chocolate (chopped), mix until smooth and shiny. Steer in 3 tablespoons of cold butter. Completely cover the cake. Keep the cake in the refrigerator until ready to serve.
