Fit a piping bag with a round tip, and fill it with the cream filling. Take one cookie and pipe two rows of frosting around the edges of the cookie, covering the top surface completely. Gently place a second cookie on top of the first, and repeat the frosting pattern. Do this again if you are doing three layers.
Decorate the top of the cookie with fresh berries, candies, macarons, fresh flowers or anything else you like. They look best when covered with a colorful assortment of treats.
The texture of the cookie and the filling stand up very well and can be refrigerated for at least a few hours. The cookies and filling can both be made a day or two in advance and then it’s short work to assemble everything on the day of serving.
