Sexy Leopard sweet cake volume approach

I have always wanted to make a leopard-print cake roll, but it is not as difficult as I thought, because the cake batter of different colors must be separately baked. In order to prevent the protein paste from defoaming, the time must be compact and not procrastinated.

The sandwich in the middle is made of purple sweet potatoes that are readily available at home. The variety of purple sweet potato is different, and the taste and sweetness are also different. My purple sweet potato is big, sweet, solid and slightly elastic, so I only added a spoonful of condensed milk. The reason for adding condensed milk is to consume it as soon as possible, and to increase the humidity and sweetness of the purple sweet potato.

In a word, the purple sweet potato filling does not need to be complicated. It can be used after being steamed and crushed into a puree. At least milk, whipped cream, sugar, etc., are adjusted according to the materials on hand and personal taste.

Soft and fluffy cake roll without cracking, my experience is that high temperature short time. Let the cake batter instantly expand and stabilize. Bake at low temperature for a long time will cause the cake to rise slowly and lose more water.

tips:
1. There is no cream in the purple potato filling, so it can be spread when the cake roll is warm, but there is also a problem that it is easy to compact the cake roll. In addition, the purple potato filling is heavy and easy to press the cake roll. In fact, the improved method is to apply only a thin layer of purple potato mash to play a role of adhesion and decoration, and roll the cake when it is warm to the hand;

2. The two-color cake batter of the leopard print only needs to bake for 1 minute to set the shape. It prevents the cake batter from being too dry and separated from the large area of the original cake batter or cracking; the baking temperature and time of the cake roll are based on Use the actual situation of the oven to adjust.
