Instructions

  • Prepare the Pans:
    Preheat your oven to 350°F (175°C). Line three 6-inch (15cm) round cake pans with parchment paper. Set aside.
  • Make the Oreo Crust:
    In a medium-sized bowl, combine the crushed Double Stuffed Oreos with the melted salted butter. Mix until the crumbs are evenly coated.
    Divide the Oreo mixture evenly among the prepared pans, pressing it firmly into the bottom to create the crust. Do not bake the crust. Set aside while you prepare the cake batter.
  • Make the Oreo Vanilla Layer Cake:
    In a large mixing bowl, cream the softened salted butter and granulated sugar together until light and fluffy.
    Add the large egg and large egg yolk, one at a time, beating well after each addition.
    Mix in the sour cream and pure vanilla extract until combined.In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
    Gradually add the dry ingredients to the wet ingredients.
    Add the whole or 2% milk. Mix until just until combined.
    Gently fold in the chopped Oreos.
  • Assemble and Bake:
    Evenly divide the cake batter between the three pans, pouring it over the Oreo crusts.
    Smooth the tops with a spatula.
    Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
    Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes before transferring them to a wire rack to cool completely.
  • Prepare the Oreo Buttercream:
    In a large bowl, beat the softened salted butter until smooth and creamy.
    Gradually add the sifted powdered sugar, beating until light and fluffy.
    Mix in the pure vanilla extract.
    Fold in the finely ground Oreo cookies until well incorporated.
  • Make the Dark Ganache:
    In a heatproof bowl, combine the dark chocolate chips or chunks and heavy cream.
    Microwave in 30-second intervals, stirring between each, until the chocolate is fully melted and the mixture is smooth.
    Let the ganache cool slightly until it thickens but is still pourable.
  • Assemble and Decorate the Cake:
    Place the first cake layer on a serving plate or cake stand. Pipe a layer of Oreo buttercream around the edge and fill it with a generous spoonful of ganache. Repeat with the second and third layers, piping buttercream and spooning ganache between each.
    Frost the outside of the cake with the remaining Oreo buttercream, piping puffs of frosting onto the top of the cake and layering Oreo cookies between the frosting. 
    Press some crushed Oreo Crumbs unto the bottom of the cake if desired. 
  • Serve and Enjoy:
    Slice and serve your Oreo Crust Cookies and Cream Cake, and enjoy the rich, creamy, and chocolatey goodness!
