Kylie took this image of Ralph Wiggum from The Simpsons (designed by Erick Flores), and set about making her cake, entitled "Cutout Ralph".
First up, her ingredients.
Then came the baking.
"It took about 5 days, working all day, like 18 hours a day," Kylie told BuzzFeed.
"I picked this design because I grew up watching and listening to quotes (from my brother) of The Simpsons, and I just really liked the design and thought it would look really neat in 3D. Also, because this is for a competition, it's a good chance to try something challenging and see if I could do it."
