Preheat oven 180°C/350°F/Gas Mark 4 and line a baking tray with greaseproof paper. Chop up the mini egg bar and white chocolate into chunks.
In a large mixing bowl add the butter and sugar. Cream until fully incorporated. Then add in the flour and mix again until incorporated.
Crush up Mini Eggs in a small cellophane bag using a rolling pin. Then add the chopped up chunks and crushed mini eggs to the dough stir in until they’re evenly spread through the dough.
Roll out golf ball size pieces of dough and pop onto the baking tray. Pat down a little to flatten and leave about a 2cm gap between each cookie as they’ll grow.
Before putting the cookies in the oven, push a few whole Mini Eggs into the tops of the cookie dough.
Bake in the oven for 7-10 mins until golden. Leave to cool.
