Flourless Oreo Cake: The Ultimate Decadent Dessert Recipe

May 22, 2025 by DottieDessert

Flourless Oreo Cake: Prepare to be amazed! Imagine sinking your fork into a decadent, intensely chocolatey cake, studded with everyone’s favorite sandwich cookie, and unbelievably, completely free of flour. Yes, you read that right! This isn’t just a cake; it’s a chocolate lover’s dream come true, and it’s surprisingly simple to make.

While the exact origins of a flourless Oreo cake are shrouded in delicious mystery, the concept of flourless cakes themselves has a rich history. Flourless cakes gained popularity as a naturally gluten-free option, allowing those with dietary restrictions to indulge in delightful desserts. The addition of Oreos elevates this concept to a whole new level of irresistible indulgence.

So, why is this Flourless Oreo Cake such a crowd-pleaser? It’s the perfect combination of textures: the fudgy, melt-in-your-mouth cake contrasts beautifully with the satisfying crunch of the Oreo cookies. The deep, rich chocolate flavor is balanced by the creamy sweetness of the Oreo filling. Plus, its flourless nature makes it a fantastic option for those avoiding gluten, without sacrificing any of the deliciousness. I promise, this cake will disappear faster than you can say “Oreo!” Let’s get baking!

Flourless Oreo Cake

Ingredients:

  • For the Oreo Crust:
    • 30 Oreo cookies, finely crushed (about 3 cups)
    • 6 tablespoons (85g) unsalted butter, melted
  • For the Chocolate Cake:
    • 1 cup (100g) unsweetened cocoa powder
    • 1 cup (240ml) boiling water
    • 1 teaspoon instant espresso powder (optional, enhances chocolate flavor)
    • 1 cup (2 sticks, 226g) unsalted butter, softened
    • 2 cups (400g) granulated sugar
    • 1 teaspoon vanilla extract
    • 1/2 teaspoon salt
    • 4 large eggs
    • 1 cup (240ml) buttermilk
    • 1 teaspoon baking soda
  • For the Oreo Cream Cheese Filling:
    • 8 ounces (226g) cream cheese, softened
    • 1/2 cup (1 stick, 113g) unsalted butter, softened
    • 3 cups (360g) powdered sugar
    • 1 teaspoon vanilla extract
    • 15 Oreo cookies, finely crushed (about 1 1/2 cups)
  • For the Chocolate Ganache (Optional):
    • 8 ounces (226g) semi-sweet chocolate, finely chopped
    • 1 cup (240ml) heavy cream
  • For Decoration (Optional):
    • Whole Oreo cookies
    • Oreo crumbs

Preparing the Oreo Crust:

  1. Crush the Oreos: Place the Oreo cookies in a food processor and pulse until they are finely crushed. Alternatively, you can place them in a large zip-top bag and crush them with a rolling pin. You should have about 3 cups of crushed Oreos.
  2. Combine with Butter: In a medium bowl, combine the crushed Oreos and melted butter. Mix well until the mixture resembles wet sand.
  3. Press into Pan: Press the Oreo mixture firmly into the bottom of a 9-inch springform pan. Use the bottom of a measuring cup or your fingers to create an even and compact crust.
  4. Pre-bake the Crust: Bake the crust in a preheated oven at 350°F (175°C) for 8-10 minutes. This helps to set the crust and prevent it from becoming soggy.
  5. Cool the Crust: Remove the crust from the oven and let it cool completely while you prepare the chocolate cake batter.

Making the Chocolate Cake:

  1. Prepare Cocoa Mixture: In a medium bowl, whisk together the cocoa powder, boiling water, and instant espresso powder (if using). Stir until smooth and set aside to cool slightly. This process, called “blooming” the cocoa, intensifies the chocolate flavor.
  2. Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes with an electric mixer.
  3. Add Vanilla and Salt: Beat in the vanilla extract and salt until combined.
  4. Incorporate Eggs: Add the eggs one at a time, beating well after each addition. Make sure each egg is fully incorporated before adding the next.
  5. Alternate Wet and Dry Ingredients: In a separate bowl, whisk together the buttermilk and baking soda. This creates a chemical reaction that helps the cake rise. Add the cocoa mixture to the butter mixture and mix until combined. Gradually add the buttermilk mixture to the batter, alternating with the flour. Begin and end with the flour, mixing until just combined. Be careful not to overmix, as this can result in a tough cake.
  6. Pour into Pan: Pour the chocolate cake batter over the cooled Oreo crust in the springform pan. Spread the batter evenly.

Baking the Cake:

  1. Bake the Cake: Bake in the preheated oven at 350°F (175°C) for 50-60 minutes, or until a wooden skewer inserted into the center comes out with a few moist crumbs attached. The baking time may vary depending on your oven.
  2. Cool the Cake: Remove the cake from the oven and let it cool in the pan for 10-15 minutes before releasing the sides of the springform pan. Let the cake cool completely on a wire rack before frosting.

Preparing the Oreo Cream Cheese Filling:

  1. Soften Cream Cheese and Butter: Make sure the cream cheese and butter are softened to room temperature before you begin. This will ensure a smooth and creamy frosting.
  2. Cream Together: In a large bowl, cream together the softened cream cheese and butter until light and fluffy.
  3. Add Powdered Sugar: Gradually add the powdered sugar, one cup at a time, beating well after each addition. Be sure to scrape down the sides of the bowl as needed.
  4. Incorporate Vanilla: Beat in the vanilla extract until combined.
  5. Fold in Crushed Oreos: Gently fold in the crushed Oreo cookies until evenly distributed throughout the frosting.

Assembling the Cake:

  1. Level the Cake (Optional): If the top of the cake is uneven, use a serrated knife to carefully level it. This will create a more even surface for frosting.
  2. Frost the Cake: Spread the Oreo cream cheese filling evenly over the top of the cooled chocolate cake.
  3. Chill the Cake: Place the frosted cake in the refrigerator for at least 30 minutes to allow the frosting to set. This will make it easier to slice and serve.

Making the Chocolate Ganache (Optional):

  1. Heat the Cream: Place the heavy cream in a saucepan and heat over medium heat until it just begins to simmer. Do not boil.
  2. Pour over Chocolate: Remove the cream from the heat and pour it over the finely chopped semi-sweet chocolate in a heatproof bowl.
  3. Let Sit: Let the mixture sit for 1-2 minutes to allow the heat from the cream to melt the chocolate.
  4. Stir Until Smooth: Gently stir the mixture until the chocolate is completely melted and the ganache is smooth and glossy.
  5. Pour over Cake: Pour the chocolate ganache over the top of the frosted cake, allowing it to drip down the sides. You can use a spatula to spread it evenly.
  6. Chill the Cake: Return the cake to the refrigerator for another 30 minutes to allow the ganache to set.

Decorating the Cake (Optional):

  1. Add Oreo Cookies: Arrange whole Oreo cookies around the edge of the cake.
  2. Sprinkle with Oreo Crumbs: Sprinkle Oreo crumbs over the top of the cake.
  3. Get Creative: Feel free to add any other decorations you like, such as chocolate shavings, sprinkles, or fresh berries.

Serving and Storing:

  1. Slice and Serve: Carefully slice the cake with a sharp knife and serve.
  2. Store Leftovers: Store any leftover cake in an airtight container in the refrigerator for up to 3-4 days.
