Ensure your sugar cookies are fully baked and cooled. Arrange them on a baking sheet lined with parchment paper.

Spread white icing on the tops of each cooled sugar cookie, then halve the marshmallows and press them into the icing-covered cookies to form snowman bodies.

Pipe out little eyes and buttons onto each marshmallow with black icing, and add an orange jimmy for each snowman's nose.

Insert chocolate jimmies into the sides of each marshmallow to create arms.

Allow the cookies to rest for about 10-15 minutes for the icing to set completely before serving.
