PASSOVER VANILLA-CHOCOLATE ICE-BOX MATZO CAKE
Ingredients
Instructions
  1. Make the ganache: gently bring 2 cups of the cream to a simmer in a small saucepan. Place the chocolate chips in a medium bowl; pour the warm cream over the chips and let it sit without stirring until the chips begin to melt, about 10 minutes. Stir until smooth. (Note: as tempting as it is, don’t add the chocolate chips to the pot with warm cream. Doing so increases the risk that the chocolate will seize.)
  2. Meanwhile, beat 1 1/2 cup of the cream with 3 tablespoons sugar, and 1/2 teaspoon of the vanilla until peaks form that just hold their shape when you pull up the beaters. Refrigerate.
  3. Beat the remaining 1 1/2 cups of the cream, 3 tablespoons sugar, 1/2 teaspoon vanilla, cinnamon, and cocoa powder until soft peaks form. Refrigerate.
  4. Place a cookie cooling rack over a sheet pan. Place one matzo on the rack. Spread to the edges with about 3 rounded tablespoons of the ganache. Scoop about 1-cup of the vanilla whipped cream in the center of the square and spread in an even layer to about 1/4-inch from the edge. Top with a second sheet of matzo and again spread with the ganache. Scoop about 1 cup of the chocolate whipped cream in the center of the square and spread in an even layer to about 1/4-inch from the edge. Repeat, alternating the two whipped creams, until you top with the final (ninth) matzo. Spoon most of the remaining ganache in the center of the top square and spread it toward the edges, teasing it here and there to begin to drip down the sides.
  5. Use two large spatulas to transfer the cake to a serving platter and refrigerate 4 hours to allow the ganache and whipped creams to soften (and become somewhat absorbed by) the matzo.
Recipe Notes

*You can buy superfine sugar or make your own: simply process regular granulated sugar in the food processor until very fine.
