                                3.
                                Put the chopped walnuts into the oven at 150 degrees and bake for about 10 minutes.
                                    
                            
                            
                                4.
                                The butter that has softened at room temperature is sent to a fluffy feathery state
                                    
                            
                            
                                5.
                                Then add powdered sugar and continue to beat at low speed
                                    
                            
                            
                                6.
                                Must be beaten evenly, and only powdered sugar can be used, fine sugar will affect the taste
                                    
                            
                            
                                7.
                                Add the eggs and continue to beat evenly
                                    
                            
                            
                                8.

                                9.
                                Put in the toasted walnuts
                                    
                            
                            
                                10.
                                Stir until there is no dry powder
                                    
                            
                            
                                11.
                                Use oiled paper to shape the shape in the mold and freeze it in the refrigerator for an hour
                                    
                            
                            
                                12.
                                After freezing, take it out and cut into biscuit cubes of about 0.5 cm, and arrange them on the baking tray.
                                    
                            
                            
                                13.
                                Put it in the preheated oven, heat up and down 170 degrees, bake for about 20 minutes
                                    
                            
                            
                                14.
                                The biscuits will be crispy when they are out of the oven
                                    
                            
                            
                                Tips: 
                                1. The dough should not be over-mixed to avoid gluten
 2. Baked until both sides are colored and it is ready
 3. I use a PE5459 oven, please adjust the baking temperature appropriately when you use other brands of ovens
