  3. In another bowl whisk oil, eggs, milk, and vanilla, set aside.
  4. Fit mixer with a paddle attachment, mixing dry ingredients on low speed for 30 seconds. Add butter, a few cubes at a time, mixing on low until the mixture looks like wet sand.
  5. Slowly drizzle in ½ of the wet mixer and beat on medium speed for 3 minutes. Scrape sides and bottom of bowl down. Add remaining ½ of the wet mixer beating on medium speed for 4 minutes.
  6. Divide batter into three separate bowls, tinting each batter a different color. Fill pastry bags with each batter.
  7. Use a ring divider and pipe in the batters, carefully remove the ring divider, wash, and repeat process in other two pans.
  8. Bake for 25 to 35 minutes, rotating halfway. A toothpick inserted should come out clean with a few moist crumbs. Let cakes rest in pans for 10 minutes before inverting onto a wire rack to cool completely.
To make the Brie Filling:
  1. When Brie is still cold, use a knife to remove the outer rind. Let Brie rest at room temperature until very soft and squishy, about 45 to 60 minutes.
  2. Once soft, beat Brie in a stand mixer fitted with a paddle attachment. It should get a little smooth, it will look a little gummy. Add softened cream cheese, beat at medium speed until combined, about 1 to 2 minutes. Scrape bowl, add powdered sugar and vanilla, beating until uniform. Refrigerate until ready to assemble.
To make the Shag Rug Frosting:
  1. In a stand mixer fitted with a paddle attachment, beat the butter until smooth and lump free, about 30 seconds to 1 minute. Scrape the bowl, add the shortening and beat until combined, another minute.
  2. With the mixture of low, add powdered sugar alternately with heavy cream, scraping the bowl and paddle as needed. Add salt and vanilla. Once incorporated, raise speed to medium-high and beat until pale and fluffy, about 4 to 5 minutes. Divide frosting into five bowls. Keep one portion of the frosting white, this will be for damming the filling and the crumb coat. The other four portions can be dyed any shade of green.
To assemble the Groovy Green Cake:
  1. Fill four pastry bags with the various green frostings. Put a dollop of frosting onto a cake board. Secure the first layer of cake onto the board. Create a moat with some white frosting. Apply a thing layer of Brie frosting inside the moat. Secure second layer and repeat. Top with final third layer. Do a thin crumb coat with white icing. Chill cake for 15 minutes. With a grass tip, layer the frosting onto the cake from bottom to top, in a randomized pattern.
