Blackberry gummy candy for the center...
Large marshmallow. Did you read that correctly? Yup. Marshmallow. With sharp scissors, cut the end like this. Keep your scissor blades clean between cuts by wiping them off with a lightly damp clean wash cloth.
With a clean new paintbrush, lightly paint the petal with food coloring of your choice. Place petals on the outside edge of the cupcake.
Put a second layer of petal on top of the first layer and slightly closer to the center. Put your blackberry candy in there too.
