Pour the simple syrup onto a small plate or shallow bowl. Place the crushed vanilla wafers on a separate plate. Dip the rim of each cocktail glass into the simple syrup, then into the crushed wafers until coated. Set the glasses aside.

Notes
Tips and Tricks
Crush the vanilla wafers finely, so they stick more evenly to the rim.
Coat the rim gently so the wafer crumbs stay in place.
Shake the cocktail well to make sure it is properly chilled before serving.
Add the banana slices and whipped cream just before serving for the best presentation.
For a neater finish, prepare the glasses before mixing the drink.
