Tender and buttery sugar cookies are topped with a fluffy homemade buttercream icing for the most delicious and festive sweet treats. This frosted butter dream sugar cookies recipe does not require refrigeration and bakes up perfectly formed Christmas cookies that hold their shape!
In the bowl of an electric mixer, softened butter until smooth and creamy, about 3-5 minutes.
Ice cooled sugar cookies.
Buttercream frosting is made with butter and therefore needs to be refrigerated. Place the cookies in a container with a lid and keep in the fridge for 4 to 5 days.
To freeze: For the best taste I recommend freezing the cookies before frosting. Cool them completely, then wrap each cookie in plastic wrap. Place them together in a plastic ziploc bag and freeze for up to 3 months. Thaw on the counter for 20-30 minutes before frosting the Christmas cookies with freshly made buttercream icing.
