Have you ever wondered how bakery cakes get those cool two and three color borders? The technique is really very easy. If you can pipe an ordinary border, you can make a multi-colored one like those on the cakes pictured below. and above.
There are two ways to accomplish the task, depending on the final result desired. For a pastel border, like on the Teddy Bear cake, we simply piped rows of different colored icings into a pastry bag like in the photo to the right. Use two, three or even four colors if you like. When you pipe the icing the colors will come out together.
If you want a more intensely colored border, like in the Beavis and Butthead cake above, you will want to actually paint the inside of the pastry bag. Take some paste food color (like in the photo at left -- we sell it in the shopping area of this site) and an artist's paint brush. Paint 4-6 stripes of the desired color(s) down the inside of the pastry bag, then fill with icing. The border will come out striped.
