Line a tray or cutting board with baking paper. Melt chocolate in the microwave, stirring every 20 seconds until smooth.
Using a teaspoon, place a dollop of chocolate onto the baking paper, trying hard to keep a round shape, and place a choc chip in the centre. Repeat with remaining chocolate.
Dip a toothpick into the food colouring and lightly trace 'veins' around the choc chip. Repeat with remaining eyeballs.
Refrigerate for 30 minutes or until set and serve.
