Take a trip back to the 60s with these psychedelic cupcakes. It'll be groovy, man!
Frost the cupcakes with white icing. Squirt a series of concentric circles of different-colored gel icing on each cupcake.
To create the tie-dye effect, draw a toothpick through the gel, moving from the center outward like a spiderweb. Arrange into a peace sign, as shown.
