The bottom layer of the Graduation Cap Cake is an upside-down cake, and the top is a square cake. I put a thin piece of cardboard under the top layer to support it. The Tassel is a Twizzler that I cut into strands at the bottom to make it look more realistic! I used a blob of icing to put over the tip of the Twizzler, so it would look like a button.
The idea came to me from a friend wanting that design, and I just brainstormed how to make it look like one. I saw a similar design with cupcakes, and I figured if the cupcakes look like a cap, then so will a bundt cake!
