Electric pressure cookers can't make cakes for several reasons and solutions:

1. The electric pressure cooker was not preheated before heating, resulting in the heating temperature not meeting the requirements. Before heating, you need to brush a layer of oil on the inner container of the electric pressure cooker and preheat it for 2-3 minutes to make the cake rise as soon as possible.

2, the flour is wrong, using high-gluten flour. If you choose the wrong flour, choose the flour again and replace the high-gluten flour with low-gluten flour or ordinary flour.

3. There is water or oil in the container containing egg white, which leads to impure egg white. If there is water or oil in the egg white container, pay attention when preparing the container next time to avoid similar situations.

4, the method of beating protein is wrong, and no sugar is added when sending half. If the protein delivery method is wrong, re-operate it according to the correct method to achieve satisfactory results.
