For each flower, cut 1 marshmallow crosswise into 5 pieces with kitchen shears to resemble flower petals. Press cut sides in colored sugar. Arrange petals, sugar-sides up, on top of dessert to resemble flower; fill center with candy.
Mix 1/2 tsp. water with a few drops of food coloring. Add to 1 cup BAKER'S ANGEL FLAKE Coconut in resealable plastic bag; seal bag. Shake until coconut is evenly tinted. Use more food coloring for a darker shade and less coloring for a lighter shade.
