Step 1

Break the block(s) of cooking chocolate into pieces and place into a large microwaveable bowl

Step 2

Add to that bowl, the butter, golden syrup and marshmallows

Step 3

Put into the microwave, and cook for 20 seconds, then stir, then another 20 seconds, then stir, then another 20 seconds - repeat this until the mixture is soft and melted (once the chocolate/butter begin to melt, you should be able to stir to melt it all, without needing to re-microwave)

Step 4

Once all melted, add in the cornflakes and use a spatula or large spoon to stir to coat the cornflakes

Step 5

Then, lay out 6 muffin cases (or 8-12 smaller cupcake cases) and spoon the mixture into each. Make sure to press it down slightly so there aren't large gaps within the mix

Step 6

If using, place 2-3 mini eggs on top of the cakes

Step 7

Put in the fridge for 10 minutes (or leave at room temperature for 30 mins) to allow the mixture to 'set' - then eat and enjoy!
