Quick & Easy Halloween Chocolate Cake

If you are looking for an Easy Halloween Chocolate Cake then you need this easy Halloween sheet cake recipe. An easy way to use up leftover Halloween candy and create a beautiful piece perfect for a Halloween party.

The Easy Halloween Cake is a simple chocolate sponge traybake decorated with a rich chocolate cream cheese buttercream. For the easy Halloween cake decoration I used my favourite Halloween sweets.

It’s nearly time for Halloween and I for one needed to make something to use up all my Halloween candy and sweets that I have been buying. There are so many brilliant ghoulish sweets available and I am easily led to buy them. I love having a mix of the sour sweets and soft chewy ones. Plus of course some chocolate because I am a chocolate fiend.

For this bake I wanted to make an easy cake that would travel well for a Halloween party but also look incredible and taste delicious. I opted for am easy chocolate sponge tray bake or sheet cake if you are baking this in America.

This Halloween sheet cake is a perfect way to use up your leftover Halloween candy and a lovely easy Halloween cake to make for a party. No matter the age of the guests it will go down well.

It’s also a great cake that parents can make and allow their children to decorate. It’s a simple chocolate sponge and the chocolate cream cheese buttercream adds a gorgeous soft chocolate topping which isn’t too sweet like normal buttercream.

What do I need for the Easy Halloween Chocolate Cake?

For this Easy Halloween Chocolate cake you only need a few ingredients to make the sponge cake part of the bake.

  • Unsalted butter or you can use a baking block like Stork which is what I used for this recipe. It makes light cakes and is always soft and at a malleable texture so easy to mix together with the sugar without having to leave it to warm up to room temperature.
  • Light brown soft sugar. Now I used this sugar along with the caster sugar to give a warmer and richer flavour to the cake. It’s only a little amount but it really does make a difference. The Easy Halloween Chocolate Cake will still work perfectly without the light brown soft sugar but if you leave it out, add the extra amount of sugar with caster sugar.
  • Caster sugar to give the Halloween traybake sponge some sweetness.
  • Eggs make the consistency of the cakes strong and adds structure and stability. It also helps combine the ingredients together.
  • Plain flour to bind the ingredients together.
  • Cocoa powder – what a chocolate Halloween cake without cocoa powder to give it a rich chocolate flavour.
  • Baking powder to help the cake rise and give a beautifully finished bake.
  • A small pinch salt to bring out the flavour of the chocolate. You don’t need much but a tiny pinch will help the finished Easy Halloween cake.
  • Semi-skimmed milk keep the mixture beautifully smooth and moist once baked.

Easy sponge tray bake

This easy sponge tray bake is exactly that. It’s also lovely easy Halloween cake. Plus with all my recipes it is super easy! It’s a soft sponge cake with added cocoa to give it a rich a delicious chocolate flavour.

For the topping of the easy sponge tray bake I added my favourite cream cheese buttercream. I love this buttercream recipe as it makes a much softer buttercream which isn’t as sweet.

To keep on the chocolate theme running through the cake I added cocoa powder to the cream cheese buttercream too. Oh my gosh it works so well. I was happily licking the spoon and the bowl when I had finished the cake.

This is an easy sponge tray bake recipe and one that you can use for any occasion if you just change the decorations. It’s my go to easy sponge tray bake and I hope it will be yours too.

What candy can I use for Chocolate Halloween Cake?

The best thing about this recipe is that you can use any types of Halloween candy for this cake. I would recommend a mix of sweets and candy. Have some softer chewy ones, some sour candy to make your face go funny, some fruity and even some chocolate too.

What is so great about this Chocolate Halloween cake is that it can be decorated with anything

Easy Chocolate Cake Recipe

This is my go to Easy Chocolate Cake recipe. It’s super easy and you only need one mixing bowl. I usually make it into a traybake but if you want to use it for a normal sponge round cake for a birthday cake or event cane you can. For this amount of mix you could make 2x 8 inch cakes. Then you can use the chocolate cream cheese buttercream on top and sandwiched in the middle. It would be delicious.

For an easy chocolate cake recipe it really easy. You just need one good mixing bowl and a wooden spoon or you can make it a mixer. I hope you enjoy this easy chocolate cake recipe as much as I do.

What size traybake tin do I need for the Halloween Traybake?

For this Easy Halloween traybake you will need a 9 inch by 12 inch rectangular cake tin. If you don’t have a traybake tin you can divide this recipe between two 8 inch cake tins and make it a layer cake instead of a traybake.

You could also half this recipe and do one layer of a cake tin you have, preferably an eight inch cake tin. It still be a sort of a traybake but in a different shape. Still the great tasting easy chocolate cake.

How do I line a traybake tin?

The best way I have found to line a traybake tin is to have a layer of greaseproof paper on top of one of aluminium foil/silver foil. Turn the traybake tin upside down and push the greaseproof paper and then aluminium foil over the tin shape.

The silver foil will help the greaseproof paper hold it’s shape. Turn the tin over and lay the greaseproof paper and silver foil over and you’ve made a liner. Pop it in the rectangle traybake tin and you’re ready to bake.
