These are the Cookies 'n' Cream cupcakes ( white cake studded with chunks of Oreo cookies, topped with vanilla bean buttercream )
To make the topper, I used red, blue, and yellow candy melts. Each color was placed in a plastic icing bag and microwaved for about 20 seconds, kneaded, then about 20 seconds more and kneaded until smooth.. Snip off tip of bag and squeeze out letters onto a sheet of waxed paper. Do one color, let harden for about 10 minutes, then do next color.
Vanilla cupcake filled with marshmallow filling, topped with white chocolate buttercream.. The graduation cap topper is made from a mini Reese's peanut butter cup, and chocolate covered saltine cracker, and fruit roll-up for the tassle. I used some melted chocolate chips to "glue" it all together.
Banana cupcake filled with banana pastry cream, topped with banana cream cheese frosting. For the topper, I used a small star cookie cutter to cut the star out of yellow-tinted fondant.
Strawberry cupcake with strawberry cream cheese frosting. Diploma scroll topper is white fondant, cut into a small rectangle and rolled. then I cut a thin ribbon of fruit roll-up to tie around it.
I was happy with the way these turned out.
