A decorative cake with buttercream frosting piped to create a shaggy grass-like texture.

Ingredients

  • 3 lbs confectioners sugar
  • 1.5 lb butter, unsalted room temperature
  • 2 tbsp vanilla bean paste
  • 5 tbsp heavy cream
  • Food coloring gels
  • 5 Grass Piping Tips
  • Piping Bags

Method

  1. Beat the butter until light and fluffy. Add the confectioners' sugar and beat until smooth.
  2. Add vanilla paste and cream. Beat on low until combined.
  3. Use the white buttercream to frost in between the cake layers and around the cake. Only apply a thin layer of white frosting around the cake. This is your "crumb coat". Refrigerate cake for 15 minutes while you prepare the frosting colors.
  4. Separate the frosting into small bowls. Add food coloring gel to your bowls to create your desired colors and transfer to piping bags fitted with grass No.233 icing tips. Suggested: 3-5 colors.
  5. Press the tip of the bag to your cake for one second and pull back immediately. The longer you squeeze the frosting, the longer your "shag" will be. Place 6-8 patches of one color next to each other to get a patchy look. Continue all around the cake.

Notes

This buttercream recipe is enough for 2 nine-inch cake rounds or 3 six-inch cake rounds.
