DIY Mutant Bunny Cake Decorating Tutorial

DIY Mutant Bunny Cake

Hal­loween is around the cor­ner, and it’s full of the usual fun—pumpkins, ghosts, witches, and candy. Let’s add a new pal to the crew—Mutant Bunny cake!

DIY Mutant Bunny Cake

I’m a big fan of a non­scary Hal­loween, and I wanted to make a cake that had just enough Hal­loween weird­ness but still main­tained the cute fac­tor. I imag­ined a fluffy white curi­ous bunny mak­ing its way to the big city from the for­est, only to be scooped up by a mad sci­en­tist intent on cre­at­ing a new species in his col­or­ful lab­o­ra­tory. Or, per­haps he is a mutant alien bunny from a far away planet! What­ever story you spin, rest assured that with this mutant bunny cake, your Hal­loween party will be all set! This guy would also be a fun cake for a mon­ster– or alien-themed birth­day party.

Left to right: ears and eyes made from fon­dant and large and small pip­ing tips

What You Need

  • A two layer, round vanilla cake recipe of your choice—baked from scratch or from the box. Optional: I dyed my vanilla cake lay­ers with pink gel color. Do it, it looks so cute! Sim­ply blend in pink gel color to your cake bat­ter before pour­ing into cake pans for baking.
  • 4 cups of vanilla but­ter­cream or 2 cans of frosting
  • Blue gel food coloring
  • An off­set spat­ula or but­ter knife
  • A bench scraper
  • A pip­ing bag fit­ted with a multi-opening tip (also known as “grass” tip)—I used the Wilton #234 tip
  • A 5-inch ball of fon­dant (white with some tinted blue for the ears, pink for the nose and ear cen­ters, and black for the pupils)
  • Parch­ment paper
  • Corn­starch for work­ing with fondant
  • Rolling pin
  • Mini­cir­cle cut­ters for mak­ing “eyes”—I use the larger ends of the pip­ing tips as cir­cle cutters.
  • A long wooden BBQ skewer, cut into two equal-length sticks

Step 1
Bake your cake accord­ing to the recipe instruc­tions. Let cakes cool com­pletely on wire racks in their pans.

Step 2
Make your but­ter­cream accord­ing to the recipe instruc­tions. Add a small amount of sky-blue gel food col­or­ing to tint it blue.

Step 3
Place a dab of but­ter­cream on a cake plate or card­board cake board.

Step 4
Care­fully remove your first cake layer from your cake pan. Use a ser­rated knife to level your cake so the top is flat.

Step 5
Place the cake cut side up on the cake plate on top of the dab of but­ter­cream to adhere.

Step 6
Using an off­set spat­ula or but­ter knife, spread a layer of but­ter­cream on top. Remove your sec­ond layer from your cake pan, lev­el­ing it as you did with the first layer. Place the sec­ond layer cut side down onto the first frosted layer.

Step 7
Next, frost the entire exte­rior of the cake.

Step 8
Using your bench scraper, smooth your but­ter­cream. Get your pip­ing bag ready! Time to pipe some hairy, blue mutant bunny fur!

Step 9
Begin to pipe your bunny fur. Start from the bot­tom and pipe your way up in lines.

Step 10
Con­tinue pip­ing until your cake sides are com­pletely cov­ered in fur.

Step 11
Make your fon­dant accou­trements. Roll out your white fon­dant to ¼-inch thick. Using your cir­cle cut­ters or pip­ing tips, cut out cir­cles for eyes in a few sizes. Roll out a lit­tle bit of black fon­dant to ¼-inch thick. Cut out cir­cles for black irises with smaller cut­ters. Adhere to white cir­cles with a dot of water. Add lit­tle dots of white fon­dant for car­toon eyes, adher­ing with a tiny dot of water. Cre­ate two 1-inch white fon­dant balls. Squish them down flat to cre­ate the bunny cheeks. Roll a small amount of pink fon­dant into a ball for the nose. Cre­ate two blue bunny ears by rolling blue fon­dant into tube­like shapes. Using a small amount of pink fon­dant, cre­ate inner ears. Adhere with a lit­tle bit of water. Push BBQ skew­ers into each ear. Make white tri­an­gle teeth by rolling out white fon­dant and cut­ting out tri­an­gles with a par­ing knife.

Step 12
Start plac­ing your eye­balls on your face!

Step 13
Place the rest of your eye­balls and the bunny cheeks.

Step 14
Now, use your pip­ing bag and pipe fur all around the eyes and cheeks.

Step 15
Keep on pip­ing and fill in the face. Once the face is fully furry, place the pink nose and tri­an­gle teeth. Plunk the fon­dant ears into the side of the cake and pipe more fur on top of the ears.

Party time! I used a cir­cle craft punch to cre­ate con­fetti out of cute striped paper for my party table. This guy has some pointy tri­an­gle incisors!

Sur­prise! Mutant bunny cake has pink insides. This cake’s giv­ing you the hairy eyeball—you bet­ter eat it before it eats you.

Happy Hal­loween, every­one! Hope you enjoyed this tuto­r­ial, and I’ll see you again real soon.
