Ingredients

  • 1 1/2 cups whole milk
  • 1/2 cup granulated sugar
  • 3 tablespoons cornstarch
  • 3/4 teaspoon peppermint extract
  • 1 large egg, plus 1 egg yolk
  • 3 ounces white chocolate, finely chopped
  • 1 to 2 drops green food coloring
  • 3 tablespoons mini chocolate chips, plus more for topping
  • 1 1/2 cups cold heavy cream
  • 1 tablespoon confectioners' sugar
  • 1/8 teaspoon peppermint extract
  • Basic Chocolate Cake, baked and cooled

Method

  • Make the filling: Bring the milk to a simmer in a medium saucepan over medium heat.
  • Whisk the granulated sugar, cornstarch, peppermint extract, egg and egg yolk in a medium heatproof bowl until smooth.
  • Gradually whisk half of the hot milk into the sugar mixture, then return to the pan with the remaining milk.
  • Reduce the heat to medium low and cook, whisking constantly, until the mixture boils and thickens, 2 to 3 minutes.
  • Transfer to a bowl (strain through a fine-mesh sieve if it looks lumpy), then stir in the white chocolate and green food coloring until the chocolate melts.
  • Press plastic wrap directly onto the surface and refrigerate until cold, at least 1 hour.
  • Stir in the chocolate chips.
  • Make the topping: Beat the heavy cream, confectioners' sugar and peppermint extract in a bowl with a mixer on medium speed until medium peaks form, 1 to 2 minutes.
  • Assemble the cake: Put 1 cake layer on a platter; spread the filling on top, stopping 1/2 inch from the edge.
  • Top with the second cake layer and press down gently.
  • Top with the whipped cream and chocolate chips.
