St. Patrick’s Inspired Rainbow Cake



I loved doing this St. Patrick inspired bright cake with a rainbow stencil and sprinkles! I used Chefmaster neon brite green for the bright green, and the rest of the rainbow colors using Chefmaster or Americolor. I used my Cricut Maker to create a stencil using a plastic poster board (Can be found at Michaels or any craft store). I found this SVG here. I used American buttercream for the colors because it’s the best buttercream when using stencils. The sprinkles used here are “Here Comes The Sun” from Fancy Sprinkles, and you can use CAKEINSPO15 for a discount on your order. The “clouds” were piped with a 1A piping tip.
