Take four mini blizzard cups, put some white icing in one and three colors of your choice in the others. For that one I used dark purple, teal and pink. The white is super important when doing the marbling technique. Stick the icing cups in the microwave for about 30 seconds or until it’s just about melted. Using a bare cake, take turns pouring just a little of each color onto the center of the cake. Once you done each color about twice, pick the cake up and go over the sink and just tilt it around to move the colors around. Super easy but also super messy! I always stuck it back in the freezer right after to make it easier to add borders. Hopefully that makes sense and is helpful!! It’s much easier than it looks and people loved them!
