How to Make Marshmallow FlowersFlatten 12 large marshmallows, then press both sides of each marshmallow in colored sugar. Use clean kitchen shears to cut 5 (1/2-inch-deep) slits in each marshmallow to resemble the petals of a flower. Cut 6 small gumdrops in half; place 1 gumdrop half, cut-side down, in center of each marshmallow flower.
Make AheadMarshmallow Flowers and pudding mixture can be made ahead of time. Do not spoon pudding mixture into ice cream cups. Refrigerate until ready to serve. Store Marshmallow Flowers in airtight container at room temperature. Spoon pudding mixture into ice cream cups just before serving; top with Marshmallow Flowers.
Make it EasyInstead of spooning the pudding mixture into the ice cream cups, spoon into resealable plastic bag. Seal the bag, then diagonally snip off one corner from bottom of bag. Squeeze the pudding mixture from bag into the ice cream cups. Then, decorate as directed.
