A burn cake is a cake with a top layer that's set on fire to reveal an edible image underneath. The trend has been popular on TikTok and has been used for a variety of occasions, including birthdays, gender reveals, and proposals.

Here's how burn cakes work:
Layers
The cake is made with two layers: a bottom layer of frosting and a top layer of wafer paper or rice paper. The frosting sheet is piped to create a border and leave a gap between it and the top layer.
Image
An image is printed onto the frosting sheet for the bottom layer and onto the wafer paper or rice paper for the top layer.
Lighting
The top layer is lit on fire, revealing the image underneath. The wafer paper burns easily because it's made of starch and oil, while the frosting sheet remains unaffected.
To avoid the image falling out, it's best to light the cake in the center. The frosting around the edge acts as a natural extinguisher, putting out the flame once the wafer paper is done burning.
