For the Colored Christmas Cookies, sift flour and baking powder and knead into a dough with sugar, egg and softened butter. Roll out dough on lightly floured work surface into a square and cut out various designs as desired.
Place on a baking sheet lined with parchment paper and bake in the oven for about 10 minutes, then let cool thoroughly. Melt chocolate in a water bath or in the microwave. Decorate Christmas cookies with liquid chocolate and sugar sprinkles and let harden.
