I tried to bake a batch of fortune cookies for upcoming bridal shower favors. It was brown at edges but still white the rest. How do you get them even brown not burnt like restaurant cookies? I baked them at 375 degrees for 5 minutes as instructed. Recipe: 2 egg whites, 1/2 tsp almond extract, 1/2 cup of flour and sugar. If i were to make chocolate version, do I add some cocoa powder? I plan to dipped them in candy melts and pink sugar pearls for theme colors. Any tips? If anyone has made them, can I used silicone mats rather than cookie sheets with cooking spray? Thanks!
