Melt the white chocolate chips in a microwave-safe container. Melt in intervals of 15-30 seconds, checking and stirring each time so that the chocolate doesn't burn.
Spread the melted chocolate out onto a parchment-lined cookie sheet in a thin layer. The chocolate slab should be about 1/4″ thick.
In a separate bowl, melt chocolate wafers in a microwave-safe bowl. Melt in intervals of 15-30 seconds, checking and stirring each time so that the chocolate doesn't burn.
Drop and drizzle the milk chocolate over the white chocolate.
Use a toothpick to create swirls in the chocolate mixture, dragging it through the chocolate.
Roughly chop up the mini eggs and spread them overtop of the chocolate in an even layer. Press larger pieces into the chocolate so that they really stick.
Place the chocolate in the fridge and allow it to harden completely before breaking into small pieces.
