  • 2 cups heavy cream, very cold
  • 1 can (14 ounces) condensed milk, very cold
  • 1 tablespoon instant coffee granules, dissolved in 1 tablespoon warm water and completely cooled
  • 14 graham crackers, about 3-inch in lengths
  • 2 tablespoons cocoa powder or chocolate shavings


  • Line a 9 x 6 x 2 baking pan with parchment paper, leaving about 1-inch overhang on all sides.
  • In a bowl, combine heavy cream, condensed milk, and liquid coffee. Using a hand mixer at low speed, whip mixture until it begins to thicken. Increase speed to medium and continue to beat to stiff peaks.
  • Arrange one layer of graham crackers on bottom of the prepared baking dish, breaking pieces as needed to fit sides. 
  • Spoon ⅓ of cream mixture on crackers and spread to cover.
  • Arrange another layer of graham crackers over the cream. Spoon and spread ⅓ of the cream mixture. 
  • Repeat with another layer of graham crackers. Spoon and spread remaining ⅓ of the cream mixture on top of crackers.
  • Cover tightly with plastic film and refrigerate overnight. Freeze for about 1 hour before serving. Or freeze for about 6 hours for ice cream like consistency.
  • Lift cake from pan using parchment paper overhang as support and transfer onto a serving platter. 
  • Sprinkle cocoa powder or chocolate shavings on top of cake or dust with cocoa powder. Cut into squares to serve.


To make chocolate shavings, run a vegetable peeler across sides of a bittersweet chocolate bar.
Use a flour sifter to easily dust top of cake with cocoa powder.
