Learn how to make a towering edible Christmas tree with this holiday riff on a classic treat.
Melt butter in a large saucepan over low heat. Add marshmallows and cook until melted, stirring constantly. Remove from heat, and stir in the food coloring. Add cornflakes and combine thoroughly. Transfer cornflakes mixture into large bowl.
On a cake stand, pile the marshmallow and cornflakes mixture high in the shape of a triangle or a Christmas tree. Tip: Wear gloves or coat your hands in cooking spray to keep mixture from sticking.
Decorate tree with white icing and M&Ms. Using a star cookie cutter, cut a star out of the yellow fondant. Attach to a toothpick and place on top of the tree.
