From a bake-sale fund-raiser to an office baby shower, brownies are always a fast, delicious fallback offering. And just because you brought them to the PTA open house doesn't mean they're not festive enough for a holiday hostess gift. Personalize -- and pretty up -- your crowd-pleaser by stenciling a big bow on top with powdered sugar. Print our template onto card stock, and cut out. Bake an 8-by-8-inch pan of brownies, let cool, and turn out upside down onto a platter. Place stencil on top; using a sifter or small strainer, dust with confectioners' sugar, and carefully remove stencil.
