Kit Kat Birthday Cake

Kit Kat Birthday Cake Recipe - SavvyMom

My son is past the phase of having his birthday cakes decorated based on a favourite cartoon character, but he still looks for something fun and festive and that screams “Happy Birthday!” This Kit Kat candy bar-coated cake fit the bill perfectly.
To make it, you simply ice a favourite two-layer cake with a thick layer of chocolate frosting and cover the sides with pieces of Kit Kat chocolate bar, nestled close together like a fence. The Kit Kats cover up any imperfections in the decorating, making this technique perfect for those who are less than confident about their cake making skills.

I chose to cover my cake with M&Ms, and my friend Julie, who made the same cake for her son Willem later in the year, used mini Oreos to grace the top of her baked birthday treat. Here at SavvyMom, we even turned the idea into an Easter dessert by covering the cake with colourful mini chocolate Easter eggs, proving that the concept can work for any special occasion, not just a birthday. The ribbon around the middle of the cake is completely optional, but does add a little something extra special to the overall look. You could also use baker’s twine in a pinch, like Julie did.

Do you have a favourite way to decorate a birthday cake without using cartoon characters or other popular themes?

You’ll Need

  • 1 8” cake (two layers) from recipe or cake mix
  • 2 cups chocolate icing
  • 1 8” cake board
  • 10 packages Kit Kat (about 40 Kit Kat sticks)
  • 1 bag of mini Oreos or M&Ms or topping of your choosing
  • Happy Birthday sign or other decorations

Prep and Cook

  • Spread a small amount of icing on the cake board and top with one of the cake layers
  • Frost the top of the layer and set the second cake layer on top of the first.
  • Frost the entire cake completely, including the sides, but don’t worry about making it smooth and perfect
  • Stick Kit Kat pieces to the sides of the cake, covering completely, leaving a very little space in between each Kit Kat
  • Wrap a ribbon around the middle of the cake, and secure with a touch of icing
  • Fill the top of the cake with mini Oreos or chosen candy
  • Top with candles and/or a Happy Birthday sign
  • To slice the cake, remove the ribbon and slide the knife between the KitKat pieces, cutting through to the centre of the cake
