Baking Tips for Success

For best results, ensure that all your ingredients are at room temperature before you begin baking. This helps the batter to mix evenly, leading to a light and fluffy cake. Additionally, make sure to properly measure your ingredients, especially the flour and cocoa powder, as too much can affect the texture of your cake. Using a kitchen scale can help with precise measurements, ensuring consistent results every time you bake.

When baking your cake, keep an eye on the oven. Every oven is unique, so check for doneness a few minutes before the recommended baking time. Insert a toothpick into the center of the cake—if it comes out clean, your cake is ready. Allow the layers to cool completely in the pans before transferring them to a wire rack. This prevents crumbling and ensures your cake layers hold their shape when assembling.

Storing and Serving Suggestions

Properly storing your Oreo Cake is essential to keep it fresh and delicious. If you have leftovers (though they might not last long), store the cake in an airtight container in the refrigerator for up to 5 days. You can also freeze the cake layers individually for up to three months. Just wrap them tightly in plastic wrap and foil to prevent freezer burn. When you're ready to enjoy, thaw them in the fridge overnight for the best texture.

When serving this cake, consider pairing it with a scoop of vanilla ice cream or a drizzle of chocolate or caramel sauce for an extra touch of indulgence. This cake also goes beautifully with a cup of coffee or tea, highlighting the coffee notes in the buttercream. No matter how you choose to serve it, this Oreo Cake is sure to be a hit with everyone!

Ingredients

For the Cake

1 ¾ cups all-purpose flour
1 ½ cups granulated sugar
¾ cup unsweetened cocoa powder
1 ½ teaspoons baking powder
1 ½ teaspoons baking soda
1 teaspoon salt
2 large eggs
1 cup whole milk
½ cup vegetable oil
2 teaspoons pure vanilla extract
1 cup boiling water
1 cup crushed Oreo cookies

For the Coffee Oreo Buttercream

1 cup unsalted butter, softened
4 cups powdered sugar
¼ cup cocoa powder
2 tablespoons brewed coffee, cooled
1 teaspoon vanilla extract
½ cup crushed Oreo cookies

Instructions

Make the Cake

Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

In a large bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt.

Add eggs, milk, oil, and vanilla to the dry ingredients and mix until combined.

Stir in boiling water until the batter is smooth. Fold in crushed Oreos.

Divide the batter between the prepared pans and bake for 30-35 minutes, or until a toothpick inserted comes out clean. Let cool.

Make the Buttercream

In a medium bowl, beat the softened butter until creamy.

Gradually add powdered sugar and cocoa powder, mixing until well combined.

Mix in brewed coffee and vanilla until fluffy. Fold in crushed Oreos.

Assemble the Cake

Place one cake layer on a serving plate. Spread a generous layer of buttercream on top.

Top with the second layer and frost the top and sides of the cake with the remaining buttercream.

Decorate with additional Oreo cookies if desired.

Ingredient Insights

The key to a moist and flavorful chocolate cake lies in the combination of quality ingredients. Use high-quality cocoa powder, as it stands out in flavor and richness. Additionally, the use of whole milk in this recipe ensures a tender crumb, while the vegetable oil keeps the cake moist. Don't skimp on the crushed Oreos—they not only contribute flavor but also add a delightful texture that enhances the overall experience of this cake.

For the buttercream, using unsalted butter allows you to control the sweetness of the frosting. Make sure to let the butter soften to room temperature for optimal mixing. The addition of brewed coffee intensifies the flavor of the cocoa powder, making the buttercream taste rich and decadent. You can easily adjust the coffee intensity based on your personal taste, whether you prefer it more subtle or pronounced.

Variations and Add-Ons

While this Oreo Cake is stunning as-is, there are numerous ways to customize it to suit various tastes. Consider incorporating flavored extracts, such as almond or hazelnut, into the cake batter or buttercream for a unique twist. For an added crunch, mix in chopped nuts or additional crushed Oreos into the batter or frosting, which will give different textures and flavors to enjoy.

If you're looking to make this cake more decadent, you could fill the layers with a chocolate ganache or add layers of mousse between the cake and buttercream. For a festive touch, try decorating the cake with seasonal sprinkles or edible flowers, elevating it for special occasions. These variations will make your Oreo Cake unique to your preferences!
