Mini Cakes: Zombie Mouth and Brain

If you follow me on social media, you’ll have seen, what some may call gruesome, the cakes that I made for Halloween this year.


Last year I attempted to make Martha Stewart’s Broken Glass cupcakes. I would have succeeded but I underestimated the time it takes to make sugar glass and ran out of time (Rookie mistake!). I had to improvise and made the limpy sugar glass into brain-like features.

This year I knew to plan ahead.


As a social media addict (I have about 10 social media accounts to run almost daily), I saw posts about How To Cake It’s Brain cake and the Zombie Mouth cupcake on Instructables floating the interweb. It was then I knew I wanted to bake something gruesome for Halloween.

Originally, I was going to make the Zombie Mouth cupcakes. But after going through the instructions, I noticed how time consuming it was. I decided that I’ll just make one but a bigger version of it. However, as Halloween was approaching, I was running short on time and realized I didn’t have a baking pan that was big enough. I made the switch to create two smaller versions of both the Brain cake and Zombie Mouth cupcake (technically a slightly  bigger version of the cupcake).

I ran into one more problem: I didn’t have a rounded bottom pan for the Brain cake. Frantically, I searched HomeSense, Winners, and Kitchen Stuff Plus. I managed to find decently sized baking cups; they weren’t rounded enough but they would do the job.


So, long story short, I decided to make two cakes instead of one.


I knew people would be curious as to how you make these cakes. Instead of doing my usual writing posts, I decided to take it to the next level: Film it.

I won’t lie. Filming the process made it take incredibly longer than it should be. I had to bake the cakes the night before Halloween and set them overnight. Constructing the zombie mouth and brain using fondant ended up consuming six hours! If I didn’t film it, it would have been, at most, four hours.


Anyway, enough chit chat. Here is the video and the full recipe below:



You will need:

  • Any cake mix (You can make it from scratch too!)
  • 1 cup of milk/water
  • ½ cup of vegetable oil
  • 3 eggs (any kind)
  • 2 baking cups (I used four; extra for mistakes!)
  • White fondant (I used Virgin Ice Premium Rolled Fondant)
  • Food colouring (red, yellow, and blue)
  • Ivory icing colour
  • Corn syrup
  • Frosting/Icing (any kind of your choice)
  • Any red coloured jam (I used strawberry)


To make the cakes:

  1. Preheat your oven to 350oF.
  2. Combine the cake mix, the milk/water, the vegetable oil, and 3 eggs into a mixing bowl. Whisk until there are no lumps.
  3. Grease your baking cups and pour in the cake batter. Make sure there’s an inch of space from the top. You can lump more batter in the centre of the baking cup dedicated for the Brain. It’ll create a nice dome shape.
  4. Place the filled baking cups into the oven for 30-33 minutes.
  5. Once the cakes are done baking, take them out and set them to cool. When they’ve completely cooled, wrap them in plastic wrap and place them in the fridge overnight. This is to help them firm up to frost/ice.
  6. The next day, take the cakes out of the fridge. Unwrap them and if needed, carve the cake intended for the Brain to your desired shape.
  7. After carving, frost/ice your cakes! This will help to make the fondant stick to the cake. So frost/ice where you are putting fondant.


The Zombie Mouth

1. To make the zombie mouth, you will need three fondant colours: flesh, gums, and teeth. Here’s how you make each colour with the fondant:

  • Flesh: Half a dime sized slather of Ivory icing colour
  • Gums: 2 or 3 drops of red food colouring. If you need more, slowly add in drops while mixing the fondant.
  • Teeth: 2 drops of yellow food colouring.

2. Roll out flat the flesh fondant. Then grab the cake intended for the Zombie Mouth and cover it with the fondant.

3. Use a knife to cut off the excess fondant. Also, it does not need to be smooth. It’s a zombie so it can be messy 🙂

4. To construct the mouth, use the gums fondant and create two snake-like pieces. They are the lips. Attach them together by creating an open mouth. Using a brush, lightly paint the centre of the fondant-covered cake with water. This helps the fondant pieces stick together. Then place the mouth onto the cake.

  • In each lip, make deep pockets. These are for the teeth to sit in.
  • Then take little balls of the teeth fondant and shape them into teeth. Once you’ve shaped them, place them in the lip pockets.

5. Now, take the leftover flesh fondant and create thin, flat strips. Then can be any size. The strips will be the ripped skin covering the top and bottom of the mouth and the rest of the cake.

6. Once you’ve placed the strips how you’d like them to appear, you can start painting your mouth! I used red food colouring as the base, mixed red and blue food colouring with corn syrup for the dark/dried blood areas. Paint the mouth however you want it to appear!

7. After it’s been painted, let it sit out to dry.


The Brain

1. To make the brain, you will need one fondant colour: pink. I added 3 or 4 drops of red food colouring to the fondant.

2. Take the fondant and make little snake-like pieces. They can be long or small. These will become the brain wrinkles.

3. Then start applying it onto the cake intended for the brain. You can twist the pieces in any direction you like. No brain is the same – every brain wrinkle is unique.

4. When you’re done, you can start to paint the brain using the red-coloured jam of your choice. For the crevices in the brain wrinkles, add in chunks of jam to create definition.

5. Once it’s been entirely painted, set it out to try.


When both the Zombie Mouth and Brain cake are completely dried, you can show off your cakes and eat them 🙂

I hope you all enjoyed the video and the cakes. I had fun making them. I’m not sure how I’ll be able to top this year’s Halloween, but I’ll figure out something.

It's more metal to suck balls without using a plastic straw 🤟
I love bubble tea and the amount of it I've been drinking made me realize how much more plastic waste I've been contributing. So recently I've made the switch to using metal straws.
While I might have to carry my straws with me and clean them myself, to save the Earth and reduce the effects of climate change, I'm willing to do it.
Earth is not just for our generation but for our future kids' generation and their kids. It is our job to make sure the Earth is still alive and kicking for them 🌎

I'm back! Nice to meat you all again 🍝
I've been MIA because of my phone. My almost 5-year old Sony Xperia Z3 bootlooped twice and I had to factor reset it, wiping everything, and I didn't get to back up all the internal data. Then my phone also corrupted a microSD card with new food photos I had, so I lost those too.
So I've been looking for a new phone, and now after 11 years of being with Sony-branded phones, I'm now part of #TeamPixel ✌️

Minus the five years of data that I lost, my phone and I are tapiokay now! 📱

Let's get 100% real here: Almost broke down because my phone died on Tuesday and currently can't afford a new phone. Luckily, factory resetting my phone fixed it! I also never backed up my phone for the 5 years I've owned it, so I lost all my contacts and other data not on my SD card. (So if you have my number, text me yours because I lost ALL. DA. NUMBERS.)
Thank you to @maestroannie for letting me use her phone for these photos! 🙏

Summer means it's Ribfest time! It's a yearly tradition for me to hit up any Ribfest I can in Ontario. Today I went to the @oakvilleribfest. Besides ribs, always gotta get the blooming onion, deep fried cheesecake, and funnel cake!

A nice, cold drink makes the summer heat beerable 🍺
I've been missing Iceland a lot lately and have been craving Einstök beer. Here's a #ThrowbackThursday post to when I ordered a non-alcoholic, alcoholic beer in Iceland. Read about this funny story on my travel account ✈ @asyoutravelit.
What's your favourite beer?

Last month I was going to try Halal Guys but made a last minute switch to Hokkaido Ramen Santouka. Check out my review on the blog. Link in bio.
