Well, Christmas biscuits are a traditional treat during the holiday season, and they're perfect for decorating with all sorts of festive colors and designs! To decorate Christmas biscuits, you'll need some basic ingredients like flour, sugar, butter, and eggs, as well as some fun decorations like sprinkles, colored icing, and edible glitter. First, start by mixing the dry ingredients together in a bowl, then add the wet ingredients and mix until the dough comes together. Roll the dough out on a floured surface and use cookie cutters to cut out shapes.
