How to Make a Lucky Charms Cake
Start with a preheated 350 degree oven. Spray 3 cake pans with nonstick baking spray.
Using a mixer, combine the cake ingredients and then divide the cake batter between the pans.
Bake the cake for 28-32 minutes or until the cake is done. The cake is done when a toothpick inserted into the center comes out clean.
Once the cake is done, remove them from the oven and allow them to cool completely.
After the cake has cooled, remove the cakes from pans and then using a cake leveler to cut off the domes.
Next, make the frosting using a mixer.
Beat together the butter, powdered sugar, vanilla, and heavy whipping cream until it has stiff peaks.
Add a 1/2 cup of frosting each to 4 bowls and then add a few drops of food coloring to each bowl.
Then start building the cake.
Add the first layer onto a cake board, and then add 1 cup of frosting to the cake and smooth it out evenly.
Sprinkle 3/4 cup of Lucky Charms on top of the frosting.
Place the next layer of cake on top and repeat.
Place the last layer of cake on top and then frost the cake with the remaining white frosting.
Add half of each colored icing to a separate piping page.
Use a knife to add dollops of colored frosting to the side of the cake.
Use the spatula to lightly spread the frosting. This will create a rainbow effect.
Add marshmallows randomly on the cake and then use the colored frosting to add dollops around the top of the cake.
Fill in the center of the cake with more cereal.
Do I Need to Refrigerate This Rainbow Cake Recipe?
Because this is a buttercream frosting, you do not need to refrigerate the cake. It is best to store the cake at room temperature. Be sure to make sure it is covered well. Use either a domed cake cover or cover the cake with plastic wrap.
Can I Buy Just the Marshmallows from Lucky Charms?
I like to use all of the cereal when I am making this cake, although I know that there are many people who like to only use the marshmallows. If you wanted a simpler way to get the marshmallows for this cake, you can buy just the Lucky Charm Marshmallows. The marshmallows can be bought online at Amazon. While you can buy them like this, I have found it is much cheaper, even if it is a little time consuming to separate the cereal.
