Here's a simple recipe for a sweet potato cake made in a frying pan using just three ingredients. First, cut the sweet potato into cubes, soak it in water to remove bitterness, and then heat it in the microwave until soft. Next, melt a cup of vanilla ice cream in the microwave and mix it with pancake mix to make the batter. Add the softened sweet potato to the batter and mix well. Pour the batter into a frying pan, cover with aluminum foil, and cook over low heat for 20 minutes on one side, then flip and cook for another 10 minutes. It's easy to make and lets you enjoy the natural sweetness of sweet potatoes.
