For a darker shade of green, add 1 to 2 additional drops of food colouring to bag. Seal bag and shake gently until coconut is evenly tinted.
Make it Easy
Pour the cake batter into large resealable plastic bag. Snip off 1 corner from bottom of bag and squeeze the batter into paper-lined muffin cups. It's much quicker and less messy than spooning the batter into each cup.
