Ingredients
  • 2 cups Buttercream Frosting
  • 1 Piping Bag
  • 1 Star Tip (Wilton 16 or similar)

Prepare the Piping Bag

First, fit your piping bag with a star tip. This tip will create the ridged texture that defines a shell border. Fold the top of the bag over to create a cuff. This makes it easier to fill without making a mess.

Fill the Piping Bag

Spoon the buttercream frosting into the prepared piping bag. Don't overfill it; about half full is ideal to maintain control. Twist the top of the bag tightly to seal the frosting in and prevent it from oozing out.

Practice Piping

Before piping directly onto the cake, practice on a piece of parchment paper. Hold the piping bag at a 45-degree angle to the cake. Squeeze gently while slightly lifting and pulling back. Stop squeezing, then touch the tip back down where you stopped and repeat. This creates the shell shape.

Pipe the Border

Position the piping bag at the edge of the cake where you want to start the border. Apply consistent pressure and pipe the first shell. Overlap each subsequent shell slightly with the previous one to create a seamless, continuous border around the entire cake.

Troubleshooting

If your shells are uneven or messy, don't worry! Gently scrape off the frosting and try again. Consistent pressure and a steady hand are key. Practicing beforehand will improve your technique.

FAQ

  • What if my buttercream is too soft?

    If your buttercream is too soft, refrigerate it for about 15-20 minutes to firm it up slightly before piping.
  • Can I use a different type of frosting?

    Buttercream is recommended for shell borders due to its consistency and ability to hold its shape. Other frostings may not work as well.
  • What size star tip should I use?

    A Wilton 16 or similar star tip is a good starting point. Experiment with different sizes to achieve your desired shell size.
