Let’s Bake a Masterpiece! Your Step-by-Step Guide

Ready to create the most festive cake of the season? Let’s break it down.

Part 1: The Funfetti Holiday Cake

1. Preheat and Prep: Preheat your oven to 350°F (175°C). Spray an 18×13-inch half-sheet pan with nonstick baking spray with flour.
2. Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
3. Mix the Batter: In a separate large bowl, whisk the sugar and room-temperature eggs until foamy and light, about 1-2 minutes. Whisk in the oil and vanilla. Gradually stir in the flour mixture, alternating with the room-temperature buttermilk, until everything is well combined. Finally, gently fold in the holiday sprinkles.
4. Bake and Cool: Pour the batter into the prepared pan and spread evenly. Bake for about 20 minutes, until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan on a wire rack, for at least 1 hour.

Part 2: The Fluffy Buttercream

5. Whip the Butter: In a stand mixer or with a hand mixer, beat the softened butter on medium-high speed until light and fluffy, 2 to 3 minutes.
6. Combine and Finish: Reduce the speed to low and add half the powdered sugar, then the milk, then the vanilla and the remaining powdered sugar. Once incorporated, increase the speed to medium-high and beat for 3 more minutes until the buttercream is light, white, and fluffy.

Part 3: Decorate Your Christmas Tree

7. Frost the Base: Spread about 3 cups of the white buttercream in a smooth, even layer over the cooled cake.
8. Prep Your Colors: Transfer ¼ cup of the white frosting to a small piping bag with a tiny (⅛ inch) opening. Tint the remaining 1 ¾ cups of frosting with green (and a drop of blue for depth) food coloring. Transfer this to another piping bag with a slightly larger (¼ inch) opening.
9. Create the Tree: Lightly trace a large triangle on the cake. Place rows of brown M&M’s at the base for the trunk. Pipe a row of green dots across the bottom of the triangle. Use a small offset spatula to gently drag each dot downward and outward in a curve. Pipe the next row of dots above, overlapping the swoops. Repeat until the tree is filled.
10. Decorate the Tree: Use the white frosting to pipe a swooping garland across the tree. Press yellow M&M’s into the garland for “lights” and red M&M’s onto the green branches for “ornaments.” Create a bow from the sour candy belt and place it on top.
11. Final Touches: Use the remaining sprinkles to create a border around the cake and pipe little white dots in the background for “snow.”

For the Frosting & Decoration:

• 1 1/2 cups salted butter (3 sticks), at room temperature
• 1 1/2 lb. powdered sugar (6 c.)
• 1/4 cup milk
• 1 Tbsp. vanilla extract
• as needed Forest green and blue gel food coloring

• Offset spatula

Method

 

1. Preheat oven to 350˚F. Spray an 18-by-13-inch half-sheet pan with baking spray. Whisk together flour, baking powder, baking soda, and salt.
2. In a large bowl, whisk sugar and eggs until foamy. Whisk in oil and vanilla. Gradually stir in the flour mixture, alternating with the buttermilk, until combined. Fold in the sprinkles.
3. Transfer batter to the prepared pan and bake until a toothpick comes out clean, about 20 minutes. Cool completely in the pan.
4. Make the frosting: Beat butter until light and fluffy. On low speed, mix in half the powdered sugar, then the milk. Mix in the vanilla and remaining powdered sugar. Increase speed to medium-high and beat until light and fluffy.
5. Spread 3 cups of white buttercream in a smooth layer on the cake. Transfer 1/4 cup of remaining white frosting to a piping bag with a small opening. Tint the rest of the frosting deep green and transfer to a piping bag with a larger opening.
6. Lightly trace a large triangle on the cake for the tree. Create a trunk with brown candies. Pipe a row of green dots across the bottom of the triangle. Use a small spatula to drag each dot down and outward in a curve. Repeat in overlapping rows until the triangle is filled.
7. Create a border with sprinkles. Use the white icing to pipe small ‘snow’ dots around the tree, and to pipe a swooping garland across the tree. Decorate the garland with yellow ‘lights’ and the tree with red ‘ornaments’.
8. Make a bow from the sour candy belt and place it on top of the tree.

Notes

Room Temperature Ingredients: For the smoothest cake batter and fluffiest buttercream, ensure your eggs, buttermilk, and butter are all at room temperature before you begin.

Make Ahead: The unfrosted sheet cake can be baked, cooled, and frozen for up to 3 months. The cake can be fully frosted and decorated up to 3 days in advance and stored at room temperature.

Swoop Technique: For the cleanest tree ‘branches,’ wipe your spatula or knife clean between each swoop through the green frosting dots.

WiseRecipes’ Top Tips for a Perfect Sheet Cake

These simple secrets will help you create a stunning and delicious holiday cake.

1. Use Room Temperature Ingredients. For a smooth, evenly mixed cake batter, your eggs and buttermilk must be at room temperature. This is also crucial for a light and fluffy, non-curdled buttercream.
2. Don’t Overmix the Batter. Once you start adding the flour, mix only until it is just combined. Overmixing can create a tough, dense cake.
3. Cool the Cake Completely. This is the golden rule of cake decorating! The cake must be 100% cool to the touch before you attempt to frost it, otherwise, you’ll have a melted, greasy mess.
4. The “Swoop” is the Secret. The decorating technique for the tree is so clever and easy. Pipe a dot, then use the tip of a small spatula or butter knife to press and drag it down and out. Wipe the spatula clean after each swoop for the cleanest look.
5. Make It Ahead! This is a great cake to prep in advance. You can bake the cake and wrap it well, and even make the buttercream. Store the cake at room temperature and the buttercream in the fridge, then just bring it to room temp and re-whip it before decorating.

Keep It Fresh! Storing Your Festive Cake

This cake is perfect for making ahead of a big holiday party.

• Storage: The fully frosted cake can be kept, covered, at room temperature for up to 3 days. If you need to store it longer, it can be kept in the refrigerator for up to a week.
• Serving: For the best flavor and softest texture, be sure to let the cake come to room temperature for at least an hour before serving if it has been refrigerated.

FAQs: Your Christmas Sheet Cake Questions, Answered!

Do I have to use a half-sheet pan?

A half-sheet pan (18×13 inches) is ideal for a thin cake that serves a crowd. You could also bake this in a standard 9×13-inch pan, but the cake will be much thicker, and you will need to increase the baking time significantly (likely to 35-40 minutes).

I don’t have piping bags. What can I use?

Sturdy zip-top freezer bags are a fantastic substitute! Just spoon the frosting into the bags, press it down to one corner, and snip a tiny hole for the white frosting and a slightly larger one for the green.

Can I make the cake from a box mix?

Yes, in a pinch! You can use two boxes of a standard white or vanilla cake mix to get enough batter for a half-sheet pan. Just prepare it according to the package directions and fold in the sprinkles before baking.

How do I make the bow from the sour candy belt?

It’s like tying a ribbon! Take your strip of the sour belt and create two loops, crossing them in the middle. You can use a tiny dab of your white frosting as “glue” in the center to help it hold its shape before placing it on top of the tree.
