Notes

Red Grapefruit Cake is a fresh dessert that is easily made in an air fryer. It blends the subtle sour-fruity aroma of grapefruit pulp with the soft texture of the cake, making it perfect for a single-serving afternoon tea. Eggs and flour provide protein and carbohydrates, while red grapefruit is rich in Vitamin C, offering simple basic nutrition. The difficulty level is medium. The key lies in stirring the batter in batches until it has no lumps and turns a pale yellow. Newbies can succeed as long as they follow the steps patiently. From preparation to serving, it takes about 35 minutes, so it won't take up much time if you crave freshly baked sweets.
