Line a baking tray with grease proof paper.
Separate your white chocolate into 3 bowls - I left 60% as plain white chocolate and dyed 25% pink and 15% green.
Heat each bowl of chocolate individually in the microwave in short bursts until melted and smooth.
Gradually add in the powered dye and stir well until you have achieved your desired colour(s).
Pour the white chocolate onto the lined baking tray and smooth out with an offset spatula.
Drizzle the coloured chocolates over the white chocolate and swirl with a skewer until you achieve a nice marbling effect.
Quickly sprinkle over your Easter eggs, popping candy and any edible decorations you like before the chocolate starts to cool.
Wait until the Easter bark has completely hardened before snapping it into pieces.
