Add the butter, cocoa powder and mini marshmallows to a saucepan. Place over low heat and stir gently until melted.
Remove the pan from the heat then pour in the Rice Krispies. Mix briefly then add the mini Creme Eggs. Then mix again until all the cereal is well coated.
Press the mixture into your lined tin. If it's too sticky to press in, let it sit for a few minutes to cool some more then try again. A metal spoon works best.
Melt the milk chocolate and butter together until smooth then spread it over the Krispie mixture. Top with Creme Egg halves and Easter sprinkles.
Pop the whole thing in the fridge for 60 minutes, then remove it from the tin, cut into bars and enjoy!

Notes
Store in an airtight container for up to 1 week.
I cut these into 9 for my photos but I recommend dividing the slab into 18 as they are very rich!
