We shared the steamed purple sweet potato cupcakes before. Today, I will help it to put on a purple jelly coat to turn it into a purple sweet potato layer cake. The purple sweet potato cake with jelly has a more charming color and a rich taste. Full of purple sweet potato fragrance, it tastes cold and refreshing, very suitable for hot summer days. Those who like purple sweet potatoes must give it a try.

Purple Sweet Potato Cake Base

The method and recipe are the same as the steamed purple sweet potato cupcakes, except that it is replaced with a 7-inch round mold and the steaming time is extended to 55 minutes. After being steamed and unmoulded, let it cool for at least 1 hour, and wait until the cake base is stable before slicing. This amount can be cut into 4 slices, but I only choose 3 more beautiful slices to use, and the mold also can’t fit in 4 slices. So save the remaining slice and eat it.

Jelly Layer

The making of the jelly layer is very similar to the pandan layer cake we shared before. Only this time the purple sweet potato has a lot of fiber, so I need to use more konnyanku jelly powder. Otherwise, it will taste like kaya rather than jelly after solidification. And it will be more difficult to demold. Add more konnyaku powder, it will taste very chewy. However, adding more konnyaku powder also makes the batter thicker and fluency is not so good.

So when layering, make sure to fill in the seams on the edges before proceeding to the next slice. In addition, it will solidify faster, so you need to boil a pot of water to keep it warm and slow down the solidification time of the jelly. In this way, there is more time to make the layering of the cake. If you want to know more about making this cake, you can check out the video of pandan layer cake, so I won’t be wordy here.
