Ann Reardon Cake

slitherio cake snake cake

Oh my goodness, our whole family has become addicted to this game … all vying for top score in the family. To be honest, the game has absolutely no point – you can’t actually win or progress and yet it is mind-numbingly addictive.

So in honor of the hours ‘wasted’ playing the game, I decided to make a cake. Based on the number of requests I have had for a cake I assume many of you have been playing it too.

To make a cake you will need:

One and half times my light and fluffy sponge cake recipe baked in two trays 38.1cm (15 inches) x 25.4cm (10 inches)
A double quantity of basic buttercream mixed with ganache (see below).

White Chocolate Ganache Recipe
300g (10.58 ounces) white chocolate
100millilitres (3.38 fluid ounces) or 1/3 cup plus 2 tsp cream (35% fat)
Heat the cream until it just starts to boil and pour over the chocolate. Leave for a minute then stir until smooth. Note if you are using compound chocolate you may need to microwave for 20 seconds to melt all the chocolate. Allow the ganache to sit at room temperature overnight or spread flat in a ziplock bag in the fridge for 2 hours so it thickens.
Whip into the buttercream to make a creamy frosting that sets firm in the fridge.

Tip: Keep the left over snakes and m&m’s handy. Everyone who gets a slice of cake will appreciate getting some extras on their plate.

Seven Tips for getting on the leaderboard:
* Don’t hit the edge! You will die. When you die you leave no mass so there is no point heading to the edge to get mass – I tried that already.
* If you’re under 500: eat dots and try and boost in front of other snakes. The darting tactic often gets me out so I only do it while I’m small.
* 500-3000: head to the middle and hang around bigger snakes. Eat their left overs. Bother the big snakes, get in their way and they might make a mistake – it is hard for them to turn in a small space.
* If you get circled don’t do little loops in the middle, go as close to the outside as you can. This tactic slows down them circling smaller, which gives more of a chance for them to make a mistake and get out.
* 3000+: Start circling smaller snakes. While you are circling watch out for other people trying to circle you. Regularly go out and make your loop bigger or irregular to make this harder or boost away if you have to.
* Never boost into a feeding frenzy. Be calm or you’ll ‘pop’. If you’re big enough then loop the feeders. If not, go slowly through picking up what you can.
* 20,000+: Now YOU are the big snake, everyone will be trying to get you out. You might want to head towards the edge where there are less snakes to bump into.

  1. What size hexagon cutter did you use, & where is best to get one from please

    • Hi Linda, Ann ordered a hexagon cutter set from the local baking store. The kit came with about 5 different cutters of varying sizes. You can make your own from some aluminium flashing. The size Ann used was about 2cm on each edge.

    • Hi Agnieszka, We love your cake! It looks so good. Your son is very lucky!

  7. For your next video, can you make a “back to school cake”?

  8. Hello! live in a country where summer and strawberries do not grow here can i replace the strawberries?

  9. Sorry for another reply but with the cakes could u do a personal video for me so I know because I’m only 11 yrs old and I live in Australia nsw so please


    • Hi Nikita, Ann doesn’t do personal videos but she says Hi. If you write to the How To Cook that PO Box address, then Ann can send you a little greeting.

  10. Can you call me please I really love all your cakes and designs I love the work that you do and stuff I really watch every video that comes out.. Here’s my number:

  11. Where would you buy the Fondant for any of your recipes?

    • Hi Cade, Source fondant at cake decorating stores or order online.

  12. Pls how do I get cream for the cake

  13. Hi Ann, do you have any idea how to make hexagons without having a special cutter? And what size is the side of your hexagons? I printed your templates and the hexagons on the pages have different size… Those on the slighterio background are smaller than the other ones…

    • Hi Agnieszka, the hexagons change size in proportion to the snake as you play the game so they don’t need to be an exact size. If you don’t have a cutter you could print a hexagon shape and cut around it with a knife – obviously that is going to take a lot longer. My cutter was 3.9cm across

  14. Dear Ann, this cake, as expected!, is a perfect representation of the game! 🙂
    I was wondering if you have a plan to make a cake inspired by the tv cartoon OCTONAUTS? A friend of mine has a boy turning 3 yo in early August and he wants “a cake of the Octonauts”! 🙂

    • Hi Fernanda, I haven’t had many requests for that one as yet, sorry


  16. Could you do a zootopia cake

  17. We have a science project and so we have to make something about DNA and as I love baking I decided to base a baking around that. Do you have any ideas to help me

  18. My score is 65 395k mass 🙂

    • Hi Pelle, That is huge!

  19. My high score on is 39,875. 🙂

  20. For the black fondant, can I use store bought? And for the Gnash, could I use milk chocolate?

    • Hi Lucy, yes you absolutely can!
