  • small sauce pan
  • 2 heat-proof mixing bowls
  • mixing bowl
  • rubber spatula
  • whisk
  • handheld mixer with whisk attachment


  • 1 whole oreo crust pre-made
  • 12 whole oreos crushed
  • 3 cups heavy whipping cream
  • 1 tsp vanilla extract
  • 4 whole egg whites
  • 8 ounces unsweetened chocolate
  • 2 tbsp unsalted butter
  • 1/4 tsp cream of tartar
  • 1 cup granulated sugar
  • 2 tbsp granulated sugar (Extra) set to the side for whipped cream


  • This recipe can be divided into five distinct sections for ease of assembly.
  • 1: Whipped Cream
  • Take three cups of heavy whipping cream and place it into the mixing bowl.
  • Add 1 cup Sugar and 1 tsp vanilla extract.
  • Whip with a handheld mixer with a whisk attachment or a kitchen top mixer until stiff peaks form and it begins to look like whipped cream.
  • For posterity taste the whipped cream and then place it in the refrigerator to cool.
  • 2: Melt the Chocolate
  • Take a small sauce pan and place about 2 inches of water in it.
  • Bring it to a medium simmer over medium heat.
  • Place the heat-proof bowl over it and add the 2 Tbsp of unsalted butter.
  • Allow it to begin melting.
  • Chop or break up all of your chocolate bars and add it to the heat-proof bowl and allow it to begin melting, stirring occasionally.
  • When chocolate is completely melted mix the butter in thoroughly, remove from heat and move on to the meringue.
  • 3: Meringue
  • This step is much more intimidating than it needs to be.
  • Meringue is essentially whipped eggs and sugar.
  • In this recipe we are going to lightly cook the eggs and sugar over the steaming water.
  • They won’t end up as fluffy, but then there is no issue with the raw eggs anymore either.
  • Place heat-proof bowl over the simmering water.
  • Add 1 cup sugar, 4 egg whites and ¼ tsp cream of tartar.
  • Use a hand whisk to whisk the ingredients together until the sugar is completely dissolved and the meringue begins to get a shimmering glossy look to it.
  • Remove from heat and whisk with a hand mixer until mixture feels like marshmallow fluff.
  • About 6 minutes on high.
  • 5: Creating the Mousse
  • Take the melted chocolate and gently fold it into the meringue, until the chocolate is well mixed.
  • This can sometimes take a little bit of doing.
  • After these are mixed, now gently mix in two thirds of the whipped cream to make the mousse.
  • The mixture should be light and fluffy, and very chocolaty.
  • 6: Assembly
  • Take your pie crust, and fill it with half of the mousse.
  • Now take half of the crumbled Oreos and spread them on top of the mousse.
  • Top this with the rest of the mousse allowing the extra mousse to form a pile towards the center.
  • Spread the mousse as necessary with a rubber spatula to give the pie symmetry.
  • Now take the last of the whipped cream and spread it over the top of the mousse and crumble the remaining Oreos over the pie.
  • Refrigerate at least 4 hours, trying not to drool as you look at it!
  • Cut into slices and serve cold.
