Indulge in pure decadence with this Ultimate Oreo Peanut Butter Chocolate Cake! A no-bake masterpiece featuring a crunchy Oreo crust, a luscious peanut butter cream cheese filling, rich chocolate ganache, and fluffy whipped cream topping—finished with a drizzle of peanut butter and mini Oreos for the ultimate indulgence.


Ingredients

For the Oreo Crust:

  • 24 Oreo cookies, crushed

  • 1/4 cup unsalted butter, melted

For the Peanut Butter Layer:

  • 1 cup creamy peanut butter

  • 8 oz cream cheese, softened

  • 1/2 cup confectioners’ sugar

  • 1/2 cup milk

For the Chocolate Ganache:

  • 1 cup semisweet chocolate chips

  • 1/2 cup heavy cream

For the Whipped Cream Topping:

  • 1 cup heavy whipping cream

  • 2 tablespoons confectioners’ sugar

For the Garnish:

  • Mini Oreos

  • Melted peanut butter drizzle


Instructions

  • Make the Oreo Crust:

    • In a bowl, mix crushed Oreos with melted butter until well combined.

    • Press firmly into the bottom of a springform pan to form an even crust. Set aside.

  • Prepare the Peanut Butter Layer:

    • In a large bowl, whisk together peanut butter, softened cream cheese, confectioners’ sugar, and milk until smooth.

    • Spread the peanut butter mixture evenly over the Oreo crust.

  • Prepare the Chocolate Ganache:

    • Heat heavy cream in a small saucepan until just simmering.

    • Remove from heat, stir in chocolate chips until melted and smooth.

    • Pour ganache over the peanut butter layer and spread evenly. Let cool slightly.

  • Make the Whipped Cream Topping:

    • Beat heavy whipping cream and confectioners’ sugar together until stiff peaks form.

    • Spread whipped cream over the cooled ganache layer.

  • Garnish and Chill:

    • Decorate with mini Oreos and drizzle melted peanut butter over the top.

    • Chill the cake for at least 4 hours or until fully set.


Notes

  • Use a food processor to crush Oreos for a finer, more even crust.

  • For a salted twist, sprinkle a pinch of flaky sea salt over the ganache before adding whipped cream.

  • The cake can be made a day ahead for easier serving.
