Slime Cupcakes

I absolutely love Halloween and all the spooky themed food that comes with it. These Slime Cupcakes fit the bill perfectly as they look rather scary with their black “burnt” sponge, bright green “toxic” buttercream and creepy candy eyes, but don’t be fooled – they taste absolutely yummy! Once you bite into their menacing exterior you’ll find gooey “radioactive” slime inside! I used a lime marmalade to create this effect, but you could use strawberry jam for a “blood and guts” theme inside too. Kids and adults alike will love making these fun slime cupcakes to disgust and delight their family and friends over the Halloween season!

To make the cupcakes sponges I creamed together the butter and caster sugar, then added the black food colouring.

I whisked in the eggs, vanilla extract and then the self raising flour.

I divided the batter into the black cupcake cases.

They baked for 20 mins, I had to use a cake skewer to check they were done as they were so black!

When they fully cooled, I used a cupcake corer to make holes in the middle of each cake.

  

I added a little bit of lime green food colouring to the lemon and lime marmalade, then spooned it into each cupcakes.

I made the buttercream by mixing together the butter and icing sugar. I added the vanilla extract and the lime green food colouring until I had a nice bright green colour.

I piped it onto the cupcakes then added the candy eyes!

Despite the spooky appearance of the slime cupcakes, they were extremely popular. Everyone was attracted to their bright and unusual colours. My friends and family were pleasantly surprised by the light vanilla flavour of the sponge and buttercream, and they loved the citrus zing of the lime marmalade filling.

  1. What a brilliant idea love this…in fact, that’s one day in half term sorted…kiddies are making slime cupcakes (with a wee tweak to make them free from) #CookBlogShare

    1. Thanks Charlotte! I did have to use a lot of black food colouring, but the effect is worth it for a one off treat!

  2. These are brilliant! I particularly love that they’re filled with green slime as well as having a toxic green top. Fantastic!

    Of course, now I have a hankering for Rose’s Lime marmalade, which I’ve not even seen for years, much less had any! 😉

  3. Wow these are so striking Kat! My kids will adore these, we’ll have to give them a go over half term. Love the green slime effect, so cool.

  4. These are fantastic! I’m not keen on orange marmalade but I love lime marmalade and would definitely like to try these. They sound so tasty as well as looking great.

    1. Me too Corina, I’m not a fan of standard orange marmalade but I really enjoyed the lime one!

  5. What are a great idea Kat. My daughter is obsessed with slime so these would be a huge hit with her. Thanks for sharing the recipe.
