This was my very first 3-D cake for my friends son's birthday. The barn is a 1/2 sheet cake cut into 4 sections, stacked and then sculpted to look like a barn and the "farm field" is a 9 x 13 cake with Little people farm animals on top. The haystacks were made from cupcakes turned upside down then iced with the grass tip. The barn doors & windows are graham crakers.
The red silo is a stack of sandwich cookies iced together and topped with a muffin cup upside down.
