This was such a cute idea we had to give it a try in the WOT Test Kitchen...

It doesn’t get more fun for Halloween than making this Mummy Cake! A bonus: It’s not hard to make! First of all, you can use any 8-9″ unfrosted cake you want. Yes, that means even s store-bought one! We won’t tell.

Keep reading because we have all the tips you need to make this one like a pro.

The key to getting a beautifully smooth, glossy ganache on this cake is chopping the chocolate baking bars as fine as possible.

Also, be sure to use true chocolate baking bars for the ganache. Covering the cake with the ganache is very easy and fun!

The other big tip to know is that when you’re ready to fill your pastry bag with the warm white chocolate mixture, you will need to decorate quickly before the white chocolate cools. Be sure to try a couple of test strips at the bottom the of cake.

Happy decorating!

Mummy Cake


  • Wire baking rack
  • Pastry bag with angled tip
  • Double boiler or a glass Pyrex mixing bowl
  • 8-9” unfrosted round cake


  • 24 oz. semisweet chocolate baking bars (chopped very fine, and pulsed in a mini chopper)
  • 1 cup heavy whipping cream
White Piping for the “Bandages”
  • 1 1/2 cup white chocolate (chips or chopped baking bar)
For the “Eyes” (You could purchase candy eyes)
  • 1 large marshmallow
  • 2 chocolate chips


  • Place your unfrosted cake on top of a wire rake over a sheet pan.
  • Add finely chopped semisweet baking bars into a heat-resistant mixing bowl.
  • Heat heavy whipping cream in a saucepan just until it begins to lightly simmer, and steam is visible.
  • Slowly, pour hot cream over the finely chopped baking pieces. Let sit for a minute.
  • Using a metal spoon, slowly stir the chocolate and cream together until you get a beautiful smooth and shiny mixture.
  • Using the spoon, start in the middle of the cake and spoon the mixture onto the cake, add another spoonful. Using the back of the spoon gently spread and continue adding a spoonful at a time of chocolate onto the top of the cake working your way to the edges. Any excess chocolate will roll over the edge. Finish the ganache by spreading and covering the sides of the cake with the back of the spoon.
  • Let the cake rest while you move to the next step.
  • Using a double boiler, or a Pyrex mixing bowl over simmering water, add the white chocolate chips or chopped white baking bar. Let the white chocolate sit over simmering water for a minute or two. Using a fork, slowly stir the pieces together until the mixture is fully melted and incorporated. Remove from the heat.
  • Place the warm melted white chocolate mixture into a pastry bag. Be sure to try a couple of test strips at the bottom the of cake. Continue making strips at the top of the cake to form the “bandages” leaving room for the eyes.
  • When completed, place the “eyes” on top of the cake. To make the eyes, cut a large marshmallow in half and place one chocolate chip in the center.
