How to make designs with macaron filling

To make fancy designs in the filling of your macarons, use the star tip or closed star tip.

  1. Pipe the macarons from the edges of the macaron in a circular motion to the center of the macaron. You’ll get a couple of ridges in the filling for the macaron.
  2. Another way to get a design in the filling for macarons is to place the piping tip on the macaron shell, let a little bit of icing come out, and then lift up. Make sure to let enough icing out to give your macaron a good amount of filling. Repeat around the macaron until the entire shell has filling and then place the other macaron shell gently on top, not to crush your design.
