Chocolate Frankenstein Cake…he did the mash, he did the monster mash, the monster mash, it was a graveyard smash!

Chocolate Frankenstein Cake…ok, so he may not be so scary, but I mean how cute is he? My sister, Asher told me I could not make him too scary or she might to be too scared to eat him! That could not happen, chocolate cake is her favorite!

I started with my favorite chocolate cake recipe, but you can use any cake recipe or box you like! Around here everything has to be chocolate….Vanilla, strawberry, no way, not in a house full of chocoholics! I even frosted both the inside and outside of my cake with chocolate frosting before adding my green buttercream layer! I know…..CRAZY!

Place your chocolate green frosted cake in the freezer for 10-15 minutes. This will harden the frosting up a bit so that the green frosting does not mix with the chocolate! I made my very favorite white chocolate buttercream frosting recipe. But feel free to use your favorite recipe or store-bought (it actually works better for this).

Honestly, you have to make this Chocolate Frankenstein cake! It’s so cute and according to Asher, very SPOOKY!

  • 1 inch cake frosted with green frosting round 9 cake with 2 layers
  • 2 cups chocolate frosting
  • 1/4 cup white chocolate chips melted
  • 3 M peanut &M's any color you like
  • 1 Twix Candy Bar*


  • Line a small plate with wax paper.
  • Take two dollops of the melted white chocolate and place on the wax paper. Smooth the white chocolate out to make two large eyes, about 2 inches in diameter.
  • Now take two of the peanut M&M's (I used brown for the eyes) and place them in the middle of both of the "eyes".
  • Place the plate with the eyes in the fridge to harden while you decorate the rest of the cake.
  • Take about half a cup of chocolate frosting and place it in a sandwich size ziplock bag. Cut a very small cut in the corner of your bag (you can also use a piping bag fitted with a small round tip). Set the bag aside for now.
  • Take a large dollop of chocolate frosting and place it on the center of the frosted cake.
  • Working from the center out use a serrated frosting knife* and smooth the chocolate frosting over the top of the cake. Go over the edge and down the side a little, continue all the way around the cake making his "hair" longer in the back.
  • Remove your eyes from the fridge*. Place a little frosting on the back of both eyes and stick them on your cake.
  • Take your last peanut M&M and stick it under the eyes as his nose. (I used brown, but green would be cute too!)
  • Now take your piping bag and draw on his mouth and scar.
  • Break or cut your Twix bar in half and stick one half on either side of the cake to make his bolts


*I used black licorice for his bolts but I would have preferred to use Twix bars.
*I used a Pampered Chef serrated frosting knife, but a basket weave (#47) piping tip would work great as well. If you have neither of these, simply use a butter knife.
*If the "eyes" have not hardened yet just place them in the freezer. It should not take long for them to harden.
*You may have some leftover frosting.
