Step-by-Step to the Best Christmas Tree Cake
This fun and festive project is a joy to prepare.
Part 1: Bake the Green Sheet Cakes & Whip Up the Frosting
Step 1: First, preheat your oven to 350°F (175°C). Prepare three, 18×13-inch rimmed baking sheets by spraying them with cooking spray and lining them with parchment paper.
Step 2: In a stand mixer, combine your 3 boxes of white cake mix, your 3 boxes of instant vanilla pudding mix, the 1 1/2 cups of vegetable oil, the 12 large egg whites, 2 1/4 cups of water, and about 20 drops of forest green food coloring. Mix on a medium speed for about 5 minutes, until the batter is smooth.
Step 3: Divide the batter evenly among your three prepared baking sheets and bake for about 15 minutes. Let the cakes cool completely, and then freeze them until firm, for about 30 minutes.
Step 4: To make the frosting, in the bowl of a stand mixer, whisk together the 1 cup of sugar, the 1 tablespoon of lemon juice, a pinch of salt, and the 6 large egg whites. Place this bowl over a saucepan of simmering water and whisk until the sugar has dissolved.
Step 5: Transfer the bowl to your stand mixer and beat on a medium-high speed for 10 to 15 minutes, until the whites hold stiff peaks and are cool. Gradually toss in your 4 1/2 sticks of room temperature butter and continue to beat until the frosting comes together. Slowly drizzle in the 1 1/2 teaspoons of vanilla extract and your leaf green food coloring.
Part 2: The Art of Building Your Christmas Tree
Step 1: Use a ruler and a serrated knife to cut your three, frozen sheet cakes into squares of the following sizes: one 9-inch, two 8-inch, one 7-inch, two 6-inch, three 5-inch, two 4-inch, two 3-inch, three 2-inch, and one 1-inch. Step 2: Spread a small amount of frosting onto a large cake board. Carefully place your 9-inch square onto the frosting. Spread a layer of frosting in the center of the cake. Step 3: Place one of your 8-inch cake squares on top, offsetting it slightly so that the corners do not line up. Continue this process of stacking, frosting, and offsetting your cake squares, working from largest to smallest. Step 4: Trim a long wooden skewer to 10 inches and insert it down through the very center of your cake from the top to add support.
Part 3: The Festive Finishing Touches
Step 1: Transfer your remaining green frosting to a piping bag fitted with a small, fluted tip. Pipe rows of separate “leaves” in a downward motion to cover all the exposed tops of the cakes and create the illusion of pine needles. Step 2: To make your star topper, preheat your oven to 300°F (150°C). Place a 2 1/2-inch metal, star-shaped cookie cutter on a parchment-lined baking sheet and fill it with your crushed clear mint candies. Bake for 4 to 6 minutes, until the candies have melted. Let it cool before unmolding. Step 3: Dust your finished tree with the desiccated coconut and white nonpareils to create a beautiful “snow” effect. Step 4: To make your “lights,” cut your 18 white gumdrops in half. Press the cut side of each gumdrop half into the bottom of a candy-coated chocolate to adhere. Press these finished “lights” into your freshly piped frosting. Step 5: Before serving, carefully place a birthday candle at the very top of your cake with your beautiful, edible star topper in front of it.

- Divide the batter among the three prepared pans. Bake for about 15 minutes. Let the cakes cool completely, then freeze for 30 minutes until firm.

- Begin stacking the cake squares on a large cake board, starting with the largest (9-inch) on the bottom. Spread a layer of frosting between each square, offsetting the corners as you stack them in decreasing size order to create a tree shape.
- Insert a long wooden skewer down the center of the cake for support.
- Transfer the remaining frosting to a piping bag fitted with a small fluted tip. Pipe rows of ‘leaves’ in a downward motion to cover all the exposed cake surfaces.
- Decorate: Dust the ‘tree’ with desiccated coconut and white nonpareils for a ‘snowy’ effect. Create ‘lights’ by attaching candy-coated chocolates to halved gumdrops and pressing them into the frosting.
- For the star topper, melt crushed mint candies inside a small, greased star-shaped cookie cutter in a 300°F oven for 4-6 minutes. Let it cool, then place it on top of the cake.
