this Recipe

Ingredients:

• For the Cake:
• 2 cups all-purpose flour
• 2 cups granulated sugar
• ¾ cup unsweetened cocoa powder
• 1 ½ teaspoons baking powder
• 1 ½ teaspoons baking soda
• 1 teaspoon salt
• 1 cup buttermilk
• ½ cup vegetable oil
• 2 large eggs
• 2 teaspoons vanilla extract
• 1 cup boiling water
• For the Chocolate Ganache Frosting:
• 1 ½ cups heavy cream
• 16 ounces semi-sweet chocolate, chopped (or chocolate chips)
• ¼ cup unsalted butter, softened
• 1 teaspoon vanilla extract
• Pinch of salt
• For the White Swirl:
• 4 ounces cream cheese, softened
• 2 cups powdered sugar
• ¼ cup milk
• 1 teaspoon vanilla extract

Preparing the Chocolate Cake Batter

1. Preheat and Prep: First things first, let’s get that oven ready! Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. I like to use baking spray with flour already in it for extra insurance against sticking. Trust me, you don’t want your beautiful cake stuck to the pan!
2. Dry Ingredients Unite: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Make sure everything is well combined. This ensures even distribution of the leavening agents, which is crucial for a light and fluffy cake.
3. Wet Ingredients Join the Party: In a separate bowl, whisk together the buttermilk, oil, eggs, and vanilla extract. Whisk until everything is nicely emulsified.
4. Combine and Conquer: Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Be careful not to overmix! Overmixing can lead to a tough cake.
5. The Boiling Water Secret: This is the key to a super moist chocolate cake! Carefully pour the boiling water into the batter and mix until smooth. The batter will be thin, don’t worry, that’s exactly what we want. The hot water helps to bloom the cocoa powder, intensifying the chocolate flavor.
6. Pour and Bake: Pour the batter into the prepared baking pan and spread evenly. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Keep an eye on it, as baking times can vary depending on your oven.
7. Cooling is Key: Let the cake cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely. This prevents the cake from sticking and allows it to cool evenly. Make sure the cake is completely cool before frosting.

Making the Decadent Chocolate Ganache Frosting

1. Heat the Cream: In a saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not boil!
2. Chocolate Melt Down: Remove the saucepan from the heat and add the chopped chocolate. Let it sit for a minute or two to soften the chocolate.
3. Stir to Smoothness: Gently stir the chocolate and cream together until the chocolate is completely melted and the mixture is smooth and glossy. Be patient, it might take a few minutes.
4. Butter and Vanilla Magic: Stir in the softened butter, vanilla extract, and salt until well combined. The butter adds richness and shine to the ganache.
5. Cool and Thicken: Let the ganache cool slightly at room temperature for about 30-60 minutes, or until it reaches a spreadable consistency. You can also chill it in the refrigerator for a shorter amount of time, but be sure to check it frequently and stir it occasionally to prevent it from becoming too firm.

Creating the Signature White Swirl

1. Cream Cheese Softening: Make sure your cream cheese is nice and soft. This is crucial for a smooth, lump-free swirl. If it’s not soft enough, microwave it for a few seconds, but be careful not to melt it.
2. Cream Cheese and Sugar Tango: In a medium bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Gradually add the powdered sugar, beating on low speed until combined.
3. Milk and Vanilla Harmony: Add the milk and vanilla extract and beat until the frosting is smooth and fluffy. Add more milk, a teaspoon at a time, if needed to reach your desired consistency. You want it to be pipeable but not too runny.

Assembling Your Hostess Sheet Cake Masterpiece

1. Frost the Cake: Once the cake is completely cool, spread the chocolate ganache frosting evenly over the top. Don’t be shy with the frosting; it’s what makes this cake so indulgent!
2. Pipe the White Swirl: Transfer the white frosting to a piping bag fitted with a round tip (or you can just use a ziplock bag with a corner snipped off). Pipe lines of white frosting across the top of the chocolate ganache, spacing them about an inch apart.
3. Swirl It Up: Use a toothpick or skewer to drag through the lines of white frosting, creating a beautiful swirl pattern. Alternate the direction of your drags to create a more intricate design.
4. Chill and Enjoy: Refrigerate the cake for at least 30 minutes to allow the frosting to set before slicing and serving. This will make it easier to cut and prevent the frosting from smearing.
5. Optional Decorations: For an extra touch of authenticity, you can sprinkle some mini chocolate chips or cocoa powder over the top of the cake before chilling.

Tips for Success

• Room Temperature Ingredients: Using room temperature ingredients, especially the eggs and buttermilk, helps the batter come together more easily and creates a more tender cake.
• Don’t Overbake: Overbaking is the enemy of a moist cake. Start checking for doneness a few minutes before the recommended baking time.
• Ganache Consistency: The ganache should be thick enough to spread easily but not so thick that it’s difficult to work with. If it’s too thick, add a tablespoon of warm cream. If it’s too thin, chill it for a bit longer.
• Swirl Technique: Don’t overthink the swirl! Just have fun with it. There’s no right or wrong way to create the pattern.
• Storage: Store leftover cake in an airtight container in the refrigerator for up to 3 days.

Variations

• Peanut Butter Swirl: Replace the white swirl with a peanut butter frosting for a chocolate peanut butter twist.
• Mint Chocolate: Add a teaspoon of peppermint extract to the chocolate ganache for a refreshing mint chocolate flavor.
• Espresso Boost: Add a tablespoon of instant espresso powder to the boiling water for a richer, more intense chocolate flavor.
