Step‑by‑Step Instructions for Hostess Sheet Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure even baking. Grease and flour a 9x13 inch baking pan, making sure to coat all corners to prevent sticking. As the oven heats, gather your ingredients—this will help streamline your baking process and keep everything organized as you prepare your delicious sheet cake.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 2 cups of granulated sugar, ¾ cup of unsweetened cocoa powder, 1 ½ teaspoons of baking powder, 1 ½ teaspoons of baking soda, and 1 teaspoon of salt. Ensure there are no lumps in your dry mix, as this will lead to a lovely, even texture in your Hostess Sheet Cake.
Step 3: Combine the Wet Ingredients
In a separate bowl, whisk together 1 cup of buttermilk, ½ cup of vegetable oil, 2 large eggs, and 2 teaspoons of vanilla extract. Mix until it's well combined and smooth, which will help ensure a rich and moist cake. Once mixed, it's time to introduce these wet ingredients to the dry mix for your sheet cake.
Step 4: Blend Wet and Dry Ingredients
Gradually pour the wet mixture into the bowl with your dry ingredients, mixing on low speed until just combined. Avoid overmixing to preserve the airy texture, giving your Hostess Sheet Cake its delightful rise. The batter should be somewhat thick but uniform as you prepare it for the next step.
Step 5: Add Boiling Water
Carefully add 1 cup of boiling water to the batter, stirring until smooth. The heat activates the cocoa powder, intensifying the flavor. Your batter will be quite thin, which is perfectly fine; this will create a moist and rich texture once baked. Ensure everything is well combined for the best results.
Step 6: Bake the Cake
Pour the batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 30-35 minutes or until a wooden skewer inserted into the center comes out clean. Pay attention to the edges pulling slightly away from the pan as a visual cue that your Hostess Sheet Cake is nearly done.
Step 7: Cool the Cake
Once baked, allow the cake to cool in the pan for 10-15 minutes. This resting period ensures that the cake is set enough to release easily from the pan. Use this time to prepare for the frosting by gathering your ganache ingredients and enjoying the delicious smell from the oven.
Step 8: Prepare the Ganache
In a saucepan, heat 1 ½ cups of heavy cream over medium heat until it just begins to simmer without boiling. Keep an eye on it, as simmering will help melt the chocolate quickly. This luscious ganache will be the star of your frosting, adding richness to your Hostess Sheet Cake.
Step 9: Melt the Chocolate
Remove the saucepan from the heat and add 16 ounces of chopped semi-sweet chocolate. Let it sit for 1-2 minutes to soften before stirring. Gently mix until the chocolate is completely melted and the mixture is smooth and glossy, creating that irresistible ganache.
Step 10: Finish the Ganache
Stir in ¼ cup of softened unsalted butter, 1 teaspoon of vanilla extract, and a pinch of salt until well combined. This addition will create a shiny and silky frosting for your Hostess Sheet Cake. Allow the ganache to cool at room temperature for 30-60 minutes until it reaches a spreadable consistency.
Step 11: Make the Cream Cheese Frosting
In a separate bowl, beat 4 ounces of softened cream cheese with an electric mixer until smooth. Gradually add 2 cups of powdered sugar while mixing on low speed. The result should be a velvety, sweet contrast to your rich ganache, ensuring every bite of your Hostess Sheet Cake is perfectly balanced.
Step 12: Adjust the Frosting
Add ¼ cup of milk and 1 teaspoon of vanilla extract to the cream cheese mixture. Beat until fluffy and smooth. If the frosting is too thick, add more milk one teaspoon at a time until you reach your desired consistency. This frosting will beautifully complement the chocolate ganache on your cake.
Step 13: Frost the Cake
Once your cake is completely cool, spread the chocolate ganache evenly over the top. Use a spatula to create a smooth layer, allowing the rich chocolate flavor to shine on your Hostess Sheet Cake. The contrast between the ganache and cream cheese frosting will create a delightful treat.
Step 14: Decorate with White Frosting
Transfer the cream cheese frosting to a piping bag fitted with a round tip. Pipe lines of frosting across the surface of the ganache, spacing them about an inch apart. This technique adds a lovely decorative touch to your Hostess Sheet Cake, making it visually stunning for any occasion.
Step 15: Create a Swirl Pattern
Using a toothpick or skewer, carefully drag it through the lines of white frosting to create a beautiful swirl pattern. This artistic detail will elevate the presentation of your cake, making it pleasing to the eye as well as the palate. Enjoy the process as you make this cake your own!
Step 16: Chill the Cake
Refrigerate the cake for at least 30 minutes to allow the frosting to set beautifully. During this time, it will firm up to create perfect slices. As you wait, imagine the joy this homemade Hostess Sheet Cake will bring to your family and friends.
Step 17: Optional Toppings
For an extra touch, sprinkle mini chocolate chips or cocoa powder over the top of the cake before chilling. This optional step adds a bit of flair to your already delicious creation. It’s your time to shine as a home cook and impress everyone even more!

Expert Tips for the Best Sheet Cake
Precise Measurements: Ensure you measure your ingredients accurately. Too much flour or sugar can lead to a dense cake, while too little may cause it to collapse.
Room Temperature Ingredients: Use eggs and cream cheese at room temperature for better mixing. This will help create a fluffy texture in your sheet cake.
Cool Completely: Allow your cake to cool completely before frosting. If it’s warm, the ganache may melt, resulting in a gooey mess instead of a stunning finish.
Mixing Technique: Be cautious not to overmix when blending wet and dry ingredients. Overmixing can result in a tough texture in your delicious Hostess Sheet Cake.
Chill for Perfection: Don’t skip the chilling step after frosting. This helps the decorations firm up, which makes slicing much easier while maintaining a beautiful presentation.

Hostess Sheet Cake Recipe FAQs
How do I choose the best cocoa powder for my sheet cake?
Absolutely! For a rich and flavorful Hostess Sheet Cake, opt for high-quality unsweetened cocoa powder. Look for brands that are labeled as "Dutch process" if you prefer a smoother, milder flavor. Avoid cocoa powders that have an expiration date as they may lose their potency over time.
How should I store leftover sheet cake?
Very good question! Keep your Hostess Sheet Cake at room temperature for up to 2 days, covered tightly with plastic wrap or in an airtight container. If you’d like to enjoy it longer, transfer the cake to the refrigerator, where it can last for up to 5 days. This will help maintain the delicious flavors, especially with the creamy frosting.
Can I freeze my sheet cake, and how do I do it?
You can absolutely freeze your Hostess Sheet Cake! First, slice the cake into individual portions. Wrap each slice tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. The cake can be frozen for up to 2 months. When you’re ready to enjoy, simply thaw the slices in the fridge overnight, and they’ll be as delightful as when they were freshly made!
What if my cake sinks in the middle after baking?
This is a common baking concern! A sinking cake often results from either overmixing or underbaking. To prevent this, be careful not to stir too vigorously when combining wet and dry ingredients, as this can develop gluten and lead to a dense texture. Always perform the toothpick test to ensure your cake is done—it should come out clean or with a few moist crumbs.
Is this recipe suitable for those with lactose intolerance?
Great consideration! To adapt the Hostess Sheet Cake for lactose-intolerant individuals, you can replace buttermilk with a non-dairy milk alternative mixed with a teaspoon of vinegar or lemon juice to replicate the tanginess. For the frosting, opt for dairy-free chocolate and non-dairy cream cheese. Your loved ones will still enjoy every delicious bite without worry!
