Instructions

Frost cupcakes with desired icing.

Place a Reese's cup on the right side of the cupcake.

Pipe a small amount of buttercream onto the Reese's cup.

Dip it into the sprinkles (this is less messy than dumping sprinkles) and place back on the cupcake.

Cut the airheads in half and place them on the cupcakes so it looks like the Reese's Cup is at the end of the rainbow.

Tips & Tricks (5)

Color Layering Technique 🌈
Use a piping bag or ziplock bag with a corner cut off to create precise, vibrant color layers when decorating the cupcakes for a perfect rainbow effect.
Frosting Consistency Hack 🧁
Ensure your frosting is at room temperature and whipped to a light, fluffy consistency for easier decorating and a more professional look.
Gold Pot Placement Pro 🏺
Place the Mini Reese Cups at a slight angle to create the illusion of a tilted 'pot of gold' for a more dynamic and playful presentation.
Sprinkle Application Trick ✨
Use a small sieve or your fingers to gently sprinkle decorations for even distribution and a more controlled, artistic look.
Candy Belt Rainbow Hack 🍬
Cut the Airhead Xtremes Belts into smaller segments and carefully arrange them to create a perfectly curved rainbow arch on top of each cupcake.
