This video shows a recipe for rich, soft chocolate cookies that can be easily made without butter. First, chop the sweet chocolate and melt it in a double boiler, then add the rice oil, sugar, and egg in that order and mix well. Next, sift in the cake flour, cocoa powder, salt, and baking powder, and mix until there are no lumps of flour left to complete the dough. Chill the finished dough in the freezer for 1 hour to make it firm and easier to shape. Cut the chilled dough into bite-sized pieces and roll them into balls, sprinkle with plenty of powdered sugar, and bake in a preheated oven at 170°C for 9-10 minutes to complete the chocolate crinkle cookies with their distinctive cracked appearance. Once the cookies are baked, let them cool completely and wrap them individually for a perfect gift.
