Custard

Oreo Layer

Method

Custard Preparation

  1. 1

    Cook the Base

    In a medium saucepan, combine the whole milk, heavy cream, and granulated sugar. Heat over medium heat until the sugar dissolves and the mixture is hot but not boiling.

  2. 2

    Mix Cornstarch and Egg Yolks

    In a small bowl, whisk together the cornstarch and egg yolks until well combined. Gradually add a few tablespoons of the hot milk mixture to the egg yolks, whisking constantly to temper the eggs.

  3. 3

    Combine and Thicken

    Pour the egg yolk mixture back into the saucepan with the remaining milk mixture. Cook over medium heat, stirring constantly until the mixture thickens and coats the back of a spoon, about 5-7 minutes.

  4. 4

    Add Vanilla

    Remove from heat and stir in the vanilla extract. Pour the custard into a bowl, cover with plastic wrap directly on the surface to prevent a skin from forming, and refrigerate until chilled, about 2 hours.

Fudge Sauce Preparation

  1. 5

    Melt the Chocolate

    In a saucepan over low heat, combine the semi-sweet chocolate chips and heavy cream. Stir constantly until the chocolate is fully melted and the mixture is smooth.

  2. 6

    Cool the Sauce

    Remove from heat and allow to cool slightly. The fudge sauce will thicken as it cools.

Assembly

  1. 7

    Prepare Oreo Cookies

    Crush the Oreo cookies into small pieces, reserving a few for garnish.

  2. 8

    Layer the Sundae

    In a serving glass or bowl, layer a spoonful of custard, followed by a layer of crushed Oreos and a drizzle of fudge sauce. Repeat the layers until the glass is filled.

  3. 9

    Top the Sundae

    Finish with a generous dollop of whipped cream on top and garnish with the reserved Oreo cookies.
