For the Buttercream Frosting

• Cream together the butter and powdered sugar in a mixing bowl. Add the vanilla extract and blend in.
  8 oz unsalted butter, 1 lb powdered sugar, 1 teaspoon vanilla extract
• Add the milk, salt, and mix until fully blended and smooth. Separate into two bowls and color one using the dark blue food gel colorant. Mix the bowl of tinted frosting until it is mixed in well.
  4 oz Milk, ½ teaspoon salt, ½ teaspoon Dark Blue food coloring gel
• Place a tablespoon of frosting in the middle of a cookie. Using a butter knife, press down on the frosting pile and move in a circular motion toward the outside edges of the cookie, spreading the frosting in a swirl motion. Lay bake on wire rack. Repeat for all cookies.
• After all the cookies are frosted either white or blue, set the wire rack into one of the baking sheets. This will catch any sprinkles. Scatter the Hanukkah sprinkles over the cookies. Let cookies set out for a few hours so that frosting sets up.
