How to Make Christmas Sheet Cake
Preheat the oven: Start by preheating your oven to 350°F (175°C). Prepare a 9×13 inch baking pan by greasing it lightly and dusting with flour for easy removal later.
Combine dry ingredients: In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1.5 cups of granulated sugar, 1 cup of cocoa powder, 1.5 teaspoons of baking powder, 1.5 teaspoons of baking soda, and 1 teaspoon of salt. This will ensure a well-blended batter!
Mix wet ingredients: Add in the 2 large eggs, 1 cup of milk, 0.5 cups of vegetable oil, and 2 teaspoons of vanilla extract. Use a mixer or whisk to blend everything together until smooth and well combined, about 2 minutes.
Add boiling water: Carefully stir in 1 cup of boiling water to the batter. This step will make the batter quite thin, but it unlocks that fabulous cocoa flavor.
Pour and smooth: Pour the batter into the prepared baking pan and use a spatula to smooth out the top. It should look glossy and inviting!
Bake: Place your pan in the preheated oven and bake for about 35 minutes, or until a toothpick inserted in the center comes out clean. The cake should look moist and springy.
Cool and frost: Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack. Once cool, frost it with your favorite frosting and decorate with colorful sprinkles to make it festive!
Optional: For an extra touch, drizzle some chocolate ganache on top before adding sprinkles.

Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free flour blend for a gluten-free delight that everyone can enjoy.

Minty Fresh: Add 1 teaspoon of peppermint extract to the batter for a festive twist, perfect for holiday gatherings.
Nutty Crunch: Fold in half a cup of chopped nuts (like walnuts or pecans) into the batter for added texture and richness.

Make Ahead Options
These Christmas Sheet Cake preparations are perfect for busy cooks looking to save time during the festive season! You can mix the dry ingredients (flour, sugar, cocoa powder, baking powder, baking soda, and salt) and store them in an airtight container up to 3 days ahead to keep everything fresh. The wet ingredients (eggs, milk, oil, and vanilla) can be pre-measured and combined in a separate bowl; just refrain from adding boiling water until you’re ready to bake, as this helps preserve that moist texture. When you’re set to serve, simply combine the wet and dry mixes, add the boiling water, pour into the pan, bake, cool, and frost your cake for a homemade dessert that tastes just as delicious! Prepare ahead, and enjoy more time with your loved ones this holiday!
How to Store and Freeze Christmas Sheet Cake
Room Temperature: Store the unfrosted Christmas Sheet Cake at room temperature for up to 3 days, covered tightly with plastic wrap to keep it moist.
Fridge: If frosted, keep the cake in the refrigerator for up to 5 days. Use a cake dome or wrap it in plastic to prevent it from absorbing odors.
Freezer: Freeze the cake (either frosted or unfrosted) in an airtight container for up to 3 months. For best results, wrap it in plastic wrap and then aluminum foil.
Reheating: To serve a frozen Christmas Sheet Cake, let it thaw overnight in the fridge, and if desired, reheat in the oven at 350°F (175°C) for about 10-15 minutes before serving.
Expert Tips for Christmas Sheet Cake
Measuring Matters: Always measure your flour accurately. Too much flour can lead to a dense cake, so using the spoon-and-level method is best.
Room Temperature Ingredients: Ensure your eggs and milk are at room temperature for better mixing and a fluffier Christmas Sheet Cake.
Don’t Overmix: Once you add the wet ingredients, mix just until combined. Overmixing can lead to a tough cake, which nobody wants!
Check for Doneness: Start checking your cake a few minutes before the suggested baking time. Ovens can vary, and you want to avoid an overbaked cake.
Cool Completely: Allow the cake to cool completely before frosting to prevent the frosting from melting. Patience pays off with this delicious dessert!

Christmas Sheet Cake Recipe FAQs
How do I choose the right cocoa powder for my Christmas Sheet Cake?
Absolutely! For the best flavor, I recommend using high-quality unsweetened cocoa powder, such as Dutch-process or natural cocoa. Dutch-process cocoa has a mellower taste and darker color, while natural cocoa tends to have a more intense chocolate flavor. Both work well, but be mindful of your chosen frosting, as it can complement or clash with the cake’s cocoa profile.
How can I store my Christmas Sheet Cake?
After baking, if you haven’t frosted the cake yet, it can be stored at room temperature for up to 3 days. Just wrap it tightly with plastic wrap! If it’s frosted, transfer it to the refrigerator where it can last for about 5 days, and consider covering it to keep it fresh and to prevent it from picking up any lingering fridge smells.
What’s the best way to freeze my Christmas Sheet Cake?
The more the merrier when it comes to leftovers! To freeze, either wrap the unfrosted cake tightly in plastic wrap, then in aluminum foil for extra protection, or place it in an airtight container. This way, it can be stored for up to 3 months. When you’re ready to enjoy, simply thaw it overnight in the fridge, and if desired, warm it in a preheated oven at 350°F (175°C) for about 10-15 minutes.
Why did my Christmas Sheet Cake turn out dry?
Very frustrating, isn’t it? A dry cake can result from too much flour being added. Always use the spoon-and-level method to measure flour carefully—scooping directly from the bag can pack it down and lead to excess. Also, ensure not to overbake; start checking on your cake a few minutes before the timer goes off.
Can I make the Christmas Sheet Cake ahead of time?
Absolutely! You can bake the cake a day or two in advance and store it unfrosted at room temperature. Just wrap it well, and when you’re ready to serve, frost it freshly so the toppings look vibrant and appealing. This allows you to enjoy the holiday festivities without feeling rushed!
Are there any dietary considerations for the Christmas Sheet Cake?
Very mindful of you! This cake contains common allergens such as gluten (from the flour), dairy (from milk), and eggs. For a dairy-free version, you can substitute the milk for almond milk or soy milk, and use a dairy-free frosting. Similarly, for a gluten-free option, you might try a gluten-free flour blend, but ensure that all other ingredients are also gluten-free as well. Always check labels for potential allergens!
