Put the condensed milk and broken chocolate into a saucepan.
Heat over a low heat until all the chocolate has melted, stirring regularly.
Add ⅔ of the broken mini eggs to the pan and mix well.
Pour the mixture into a lined baking tray and top with the remaining broken eggs.
Leave to cool at room temperature, then refrigerate for 4 hours. Cut into squares.
Notes
You can half the size of this recipe if you wanted to make less. Setting times may change. You can use a medium size Tupperware to set a smaller portion.
Cutting mini eggs with a knife is near impossible. We put ours in a zip-loc bag and broke them up with a rolling pin.
If you don't have a rolling pin to crush the mini eggs, you can use the bottom of the condensed milk can before you open it.
Make sure you melt the chocolate into the condensed milk on a low heat. You don't want to heat it too high, otherwise it will split. Do not let it boil.
