I found a picture of a seahorse online, blew it up to 9×13 and cut it out for this seahorse cake. I then baked a 9×13 cake. Next I laid the picture over the cake and used a bread knife to cut the shape out. The fin on back was cut out separately.
I then mixed two colors of yellow buttercream. I frosted the front of the seahorse light yellow and the back a dark yellow and blended them together. The fin is light yellow. I then used a number 3 tip to pipe the dark yellow lines on the face and the fine on the head. I carefully placed the fin in position and then added the lines with and number 3 tip. Next I piped on the thick wiggly lines on his body.
I then made a thin border with the same number 3 tip. Finally, the eye was piped with orange frosting and a #3 tip. The cake board is covered with blue wrapping paper and plastic wrap.
