In advance: Make flowers. Using royal icing, make 28 tip 225 drop flowers for each pair of bells; add tip 2 dot centers. Make extras to allow for breakage and let dry.
Bake and cool bells using your favorite brownie recipe or firm-textured cake batter such as pound cake; unmold. Ice bottom of treats with melted candy; let set. Cover treats with melted candy; let set. Cover treats again if desired. Using royal icing, attach flowers and add dots with tip 2. Attach tops together with melted candy; let set. Tie ribbon bow and attach with dots of icing.
Drop flowers are a great way to add flowers quickly. Pipe drop flowers in buttercream directly on your cake, or pipe in royal in advance and place your flowers anywhere. Flowers will be sharper in definition when piped in royal.
