Ingredients

For the cupcake sponge

  • 175 g Baking spread (or butter) softened, unsalted
  • 175 g Caster sugar
  • 3 Eggs large
  • 2 tsp Vanilla extract
  • 175 g Self raising flour
  • 25 g Black food colouring

For the buttercream

  • 200 g Butter softened, unsalted
  • 400 g Icing sugar
  • 1 tsp Vanilla extract
  • 1-2 tbsp Milk
  • Green food colouring
  • Yellow food colouring

For the filling and decoration

  • 150 g Tinned custard
  • Green food colouring
  • Candy eyes
  • Green sprinkles

Instructions

  • Pre-heat your oven to 140C Fan/325F/Gas Mark 3, and line a cupcake tin with cupcake cases (ideally black ones)
  • For the cupcake sponge, mix together the baking spread and caster sugar, ideally using an electric mixer, for 5 minutes until smooth and fluffy
  • Add the eggs and vanilla extract and whisk them in well
  • Then gently whisk in the self raising flour
  • Add the black food colouring and mix in well
  • Divide the mixture between the cupcakes cases, and bake them for 25-30 minutes or until a skewer inserted in the centre of the cupcakes comes out clean. Put them on a rack to cool completely
  • Once the cupcakes are fully cool, use a cupcake corer or a knife to make holes in the middle of each cake
  • Add a little bit of green food colouring to the custard and mix it in, then spoon it into each cupcake
  • Make the buttercream by mixing together the butter and icing sugar until smooth, then add the vanilla extract, milk and the green and yellow food colourings until you have a bright green colour. You can add more milk if the buttercream is too stiff
  • Using a piping bag, pipe the buttercream onto the cupcakes. Or spread it on with a spoon. Decorate with the candy eyes and sprinkles
  • Store in an airtight container in a cool place, eat leftovers within 3 days

Notes

  • Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
  • For the best results, use good quality professional food colouring. My favourite brands are Pro Gel and Sugarflair.
  • I use a baking spread for the cupcakes and unsalted butter for the buttercrream.
  • I got the candy eyes in my local supermarket and they are pretty widely available around Halloween, but you can purchase them online too. Do check the ingredients if you are vegetarian or if you have any allergies as some can contain insect derived food colourings, egg white or milk powder. Or you can make your own by melting some dark chocolate and piping a small circle onto a white chocolate button.
  • Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
  • For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
