    Red and Green and lots of CANDY make this one of the most festive Holiday cakes you will ever see!

    Christmas Cake

    To make this cake you will need:

    2 white cake recipes (or 2 boxes of white cake)

    2 batches whipped vanilla buttercream (recipe below)

    red and green McCormick Food Color

    rock candy (I used red, pink, green, and light green)

    rotating cake stand

    small offset spatula

    bench scraper


    pastry bags and four #10 decorating tips

    Begin by preparing the first white cake. Add 2 teaspoons of red food color. Divide the red cake batter between 2 prepared* 8-inch round cake stands.

    *You can prepare a pan with baking spray, GOOP, parchment paper, or the butter and flour method.

    Bake according to recipe or box directions. When done baking, remove from oven and allow to cool to room temperature. Once you can handle the cake, carefully remove from pan and level the cake if needed.

    Repeat this with green food color.

    Once all cakes are baked and leveled, place in freezer until ready to assemble the cake.

    Prepare whipped vanilla buttercream. You will need at least 5 cups to cover this entire cake. It will be used between each layer (1/2 – 3/4 cup) as well as for the crumb coat and final coat. The remaining buttercream with be divided into four bowls.

    The remaining buttercream with be divided into four bowls. For the darker red, I used about 2 teaspoons. The light red (pinkish) was about one teaspoon. (Your amounts may vary depending on how much frosting you have left over. There was about 1 cup of the whipped vanilla buttercream in each bowl for me.) The darker green was about 2 teaspoons food color and the light green was a scant teaspoon.

    Once all colors are prepared, fill pastry bags. Each bag should be fitted with a #10 tip. (You can also use a #5, #7, or #12 if that’s what you have. Any small open round tip will work.)

    How to Assemble This Christmas Cake

    • Place the first layer on a rotating cake stand. (I started with red, but that was only because I was using a green cake stand and wanted some contrast. You can start with whichever color you prefer.)
    • Cover with about 3/4 cup whipped vanilla buttercream. Add next layer of cake, it should be the opposite color. (If you started with red, your next layer should be green.)
    • Repeat this process with all the layers. Once you have added your final layer, cover the cake with a thin coat of whipped vanilla buttercream. This is called a crumb coat and will seal in all the crumbs. Set cake in fridge to chill for about 15-minutes.
    • Now you will place the final “beauty” layer of frosting on the cake. Try to get it as smooth as possible. (I offer tips and tricks on how to get a smooth layer of frosting here.)
    • Using a toothpick, draw a line on the cake. Start at the very bottom and move up diagonally. Once you get to the top of the cake, make a spiral design ending in the center.
    • Grab your frostings and start piping dots. The dots will be covered with rock candy, so they do not need to be perfect. Place the dots along and next to the line you made with the toothpick. Starting with your first color, move all along the line on the top and side of the cake. Then grab your green and start again.  (You can also cluster colors, as in, put a few red dots right next to each other, a few green dots right next to each other, etc.)
    • Now take your rock candy and break it up. Place each color in its own bowl.

    Gently place the rock candy on the same color frosting. Be careful not to get your fingers in the white frosting. You can also use a tweezers to place that candy. Cover all of the red and green frostings in the corresponding rock candy color.

    When you are done, chill the cake until ready to serve. It is very easy to cut this cake, even when it is cold.

    Creating a beautiful Christmas Cake doesn’t have to be hard! This cake will take a little time to put together, but once you get the hand of it, you are golden. If you create this cake please do tag me on social media! <3

    Whats rock candy. ????

      I love this cake. Just wanted to know about how much rock candy you used? About a pound or was it more? Thank you!

    Love checking into your live feeds!

    Your husband did an awesome job! Now let’s work on getting my wife to help in the cake kitchen!!

    Such a festive and beautiful, bright, happy Christmas cake, Amanda! Your creativity is endless, my friend! I love the rock candy atop this cake! xo

    This would be a great baby reveal cake. Boy? 2 shades of blue layers or Girl? 2 shades of pink. Outside the same with pink & blue swirl. WHAT FUN!!!

      Love that!!!

        Very nice! Is there any substitute for the white cake recipe?😊

    What a gorgeous cake!! And it doesn’t look terribly hard to decorate. Do you have any tips on transporting this without ruining the icing and decorations?

      If the cake is chilled it is VERY sturdy. 🙂 In terms of transporting… depends on if you are flying? Driving? It should be fine on a flat or level surface in a car with nothing around it that could bump it.
