                                Hit until the pattern is not easy to disappear
                                    
                            
                            
                                5.
                                Sift in half of the powder that has been sieved in advance

                                7.
                                Use a spatula to continue to mix evenly
                                    
                            
                            
                                8.

                                9.
                                Squeeze it onto a tarp-covered baking pan, about 50
                                    
                            
                            
                                10.
                                Put it into the preheated 160 degree oven and bake for about 15 minutes
                                    
                            
                            
                                11.
                                After baking, take out the biscuits, put the uneaten biscuits in an airtight box, and eat as soon as possible
                                    
                            
                            
                                Tips: 
                                Different oven models have different tempers, so the temperature is for reference only.
