In the new year, let's pay a new year call to everyone first! Good luck to everyone in the Year of Rabbit! ! ! At the beginning of the year, relatives will visit my house and want to make some cookies and cakes, but the temperature rises in the first few days of the year and a lot of food is put in the refrigerator. I was afraid that the cake would go bad outside, so I put the idea of making a cake on hold and simply made some snacks! I made four shapes of this two-color cookie, and the steps of the chessboard cookie are the most complicated, so the step diagram takes the chessboard cookie as an example! Ingredients: low flour 185g butter 100g water 5ml egg yolk 1 vanilla extract with a little cocoa powder 15g whole egg liquid 2/3 fine sugar 100g.
