Kit Kat cake recipe

If you’re contemplating your child’s next birthday cake and want something that’s easy, quick and has plenty of “wow factor”, the Kit Kat cake is the answer. No special baking skills are required to create this colourful, fun, eye-catching cake that will impress adults and kids alike!

Serving Size:

Serves 16



  • 10 packs Kit Kat chocolate
  • 1 chocolate cake

    Buttercream icing

  • 2 packs M&M's
  • 300 g butter (softened)
  • 3/4 cup cocoa (sifted)
  • 5 tbs milk


Break up your Kit Kats into two-finger pieces. Snap your regular sized Kit Kats into pairs while they are still in their packets, this way you are not using your fingertips and transferring your fingerprints.

Use your favourite chocolate cake recipe and divide the mixture into two 9-inch (22cm) cake pans. Once cooked (when a skewer comes out clean), allow to cool completely. Don’t worry if your cakes do not look perfect - they don’t need to!

Once the two chocolate cakes are cooked and cooled, remove from baking pan and trim off the “dome” that forms on most cakes so that the cakes are perfectly flat on the top and bottom.

To make the buttercream, use an electric mixer to beat the butter until it is pale and fluffy. Add the icing mixture and cocoa a little at a time until fully incorporated. When this is fully combined add the milk, and the chocolate buttercream will become light and fluffy.

To assemble, put a dollop of buttercream on the serving plate or cake board and glue down the first layer of cake. Then, cover the first layer with buttercream and lay down your second flat layer of cake. Cover the whole cake completely (around the sides and the top) with the buttercream icing and be generous about it.

Place the Kit Kat pairs around the sides of the cake, pushing them into the buttercream icing, and continue around the circumference of the cake.

Fill the top with the M&Ms, and use a colourful ribbon to tie around the cake for a striking finish. As well as being decorative, a ribbon provides additional support to the cake.


  • Make this Kit Kat cake using your favourite chocolate cake recipe. Any cake will do. Just use your 'go-to' cake and bake it in two tins.
  • Make things easier on yourself by baking the cake ahead of time, covering it with plastic wrap, then putting it in the freezer.
  • The amount of Kit Kats needed depends on which sizes you buy - basically you'll need around 40 individual fingers (but you can buy more, just in case).
  • You can substitute the M&Ms with Smarties, jelly beans, Flakes or Mars Bars. White chocolate Kit Kats also look fabulous around a white chocolate mud cake.
