To make a simple teddy bear cake, you will first need to bake two round cakes and let them cool completely. Once cooled, stack the cakes on top of each other and use a knife to trim them into an oval shape. Next, cover the entire cake with a layer of brown frosting to create the bear's fur. Use fondant to create the bear's ears, snout, eyes, and nose. Additional decorations such as a ribbon or bowtie can be added to give the teddy bear cake some personality.
