Ingredients for Oreo Cookie Cake

Before diving into the process of creating this delectable Oreo cookie cake, let’s take a closer look at the ingredients you’ll need to gather. Every element is carefully chosen to bring out the best in this cake—creating a balance of textures, sweetness, and rich Oreo flavor.

For the Oreo Cookie Dough:

• 3/4 cup unsalted cultured butter, at cool room temperature: This will provide a rich, buttery flavor and help the cake achieve that tender, melt-in-your-mouth texture.
• 1 cup light brown sugar, packed: The brown sugar gives the cake a subtle molasses flavor, enhancing the overall depth of sweetness.
• 1/4 cup granulated sugar: Regular white sugar balances the richness of the brown sugar, ensuring the cake isn’t overly sweet.
• 2 large eggs, room temperature: These will help bind the ingredients together and provide moisture to the cake.
• 1 large egg yolk, room temperature: The additional yolk adds to the richness and ensures the cake stays moist and chewy.
• 2 teaspoons vanilla extract: A touch of vanilla gives a comforting, sweet flavor that complements the richness of the butter and sugar.
• 2 1/3 cups all-purpose flour: The flour is the base of the cake and helps it achieve the right structure and texture. It is crucial to measure your flour correctly—spoon it into your measuring cup and level it off to prevent using too much.
• 3/4 teaspoon baking soda: This helps the cake rise and become light and fluffy.
• 1/2 teaspoon fine sea salt: Balances the sweetness of the cake and enhances the flavors of the other ingredients.
• 2 cups chopped Oreos: The star of this dessert! Chop the Oreos into rough pieces so that they distribute evenly through the dough, giving every bite a bit of Oreo crunch.

For the Vanilla Buttercream Frosting:

• 6 tablespoons unsalted butter, room temperature: The foundation of a creamy, fluffy frosting.
• 1 cup powdered sugar: This gives the frosting its sweet, melt-in-your-mouth texture and sweetness.
• 2 teaspoons heavy cream: Adds richness and helps the frosting reach the perfect consistency.
• 1/2 teaspoon vanilla extract: For a comforting, familiar flavor that complements the Oreo cookie cake.
• Pinch of fine sea salt: A small pinch of salt enhances the flavors and balances the sweetness of the frosting.

Step-by-Step Instructions: How to Make Oreo Cookie Cake

Step 1: Prepare the Cake Pan Preheat your oven to 350°F (180°C). Grease the bottom and sides of a 9-inch cake pan or springform pan with butter. If you’re using a cake pan, you may want to line the bottom with two long strips of parchment paper in the shape of an “X” and place a parchment round at the bottom. For a springform pan, you only need to line the bottom.

Step 2: Make the Cookie Dough In a stand mixer or with a hand mixer, beat the butter, brown sugar, and granulated sugar together until light and fluffy. This will take about 3 minutes, allowing the butter and sugar to cream together. The air incorporated in this step will help make the cake light.

Add the eggs and egg yolk one at a time, mixing well after each addition. Don’t forget to scrape the sides of the bowl to make sure everything is well incorporated. Add the vanilla extract and mix until combined.

Step 3: Add the Dry Ingredients In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients in the mixer. Mix until just combined. Be careful not to overmix, as this can make the cake dense.

Once the dry ingredients are incorporated, fold in the chopped Oreos. Using an offset spatula or a spoon, evenly spread the dough into the prepared pan.

Step 4: Bake the Cake Place the cake in the preheated oven and bake for 22-30 minutes. The exact baking time may vary based on your oven and the type of pan you use. Keep an eye on the cake, and test for doneness by inserting a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs, the cake is ready.

Once baked, remove the cake from the oven and allow it to cool completely in the pan. If using a cake pan, gently lift the parchment paper to remove the cake. Transfer it to a cooling rack and let it cool before frosting.

Step 5: Make the Buttercream Frosting While the cake cools, make the vanilla buttercream frosting. In a mixing bowl, beat the butter until smooth and creamy. Add the powdered sugar gradually, mixing until combined. Add the heavy cream, vanilla extract, and a pinch of salt, and continue to beat until the frosting becomes light and fluffy.

Step 6: Decorate the Cake Once the cake has cooled completely, transfer it to your serving plate. Fill a pastry bag fitted with a star tip (or any desired tip) with the vanilla buttercream frosting. Pipe the frosting in a decorative swirl or any pattern you like across the top of the cake. For an added touch, garnish with colorful sprinkles, mini Oreos, or crushed Oreos.

Step 7: Serve and Enjoy! Slice up the cake, serve, and enjoy! The Oreo cookie cake pairs beautifully with a glass of milk or a scoop of vanilla ice cream for the ultimate dessert experience.

Pro Tips and Variations

1. Proper Flour Measurement Properly measuring your flour is crucial for achieving the best texture in your Oreo cookie cake. Always use the spoon-and-level method—spoon the flour into your measuring cup and level it off with the back of a knife. Alternatively, use a kitchen scale for precise measurements.

2. Customizing the Oreo Flavor Oreo cookies come in a variety of flavors—Golden Oreos, Java Chip, Halloween Orange, and even limited-edition flavors. Feel free to experiment with different Oreo varieties to customize the flavor of your cake.

3. Frosting Variations While vanilla buttercream is a classic pairing with the Oreo cookie cake, you can easily switch it up. Consider using chocolate fudge frosting for an even richer flavor, or try a cream cheese frosting for a tangy twist. If you’re feeling adventurous, drizzle some homemade chocolate ganache on top or spread peanut butter frosting for a fun variation.

4. Make Ahead Tips This cake is perfect for prepping ahead of time. If you’re making it the day before an event, simply bake the cake and prepare the frosting, then assemble it the next day. The cake will taste just as delicious on the second day, if not better, as the flavors have time to meld together.

5. Freezing the Cake If you want to prepare this cake in advance, you can freeze it! Freeze individual slices or the whole cake in an airtight container for up to one month. When ready to serve, simply thaw it at room temperature for a few hours.

Serving Suggestions

Oreo cookie cake is a decadent dessert that can stand on its own, but it also pairs wonderfully with a few complementary treats:

• Vanilla Ice Cream: Serve with a scoop of vanilla ice cream for a double-dessert treat that’s rich and creamy.
• Whipped Cream: A dollop of lightly sweetened whipped cream adds a light contrast to the rich cake and frosting.
