Mint Chocolate Chip Snowball Cookies

Preheat the oven to 350 degrees F (175 degrees C). Line a baking sheet with parchment paper.

Combine butter, sugar, vanilla extract, and salt in a large bowl; beat using an electric mixer until smooth and creamy. Slowly add flour and mix in. Add mint chocolate chips until well incorporated. Roll dough into 1-inch balls and place on the prepared baking sheet.

Bake in the preheated oven until bottom of cookies start to lightly brown, 16 to 20 minutes. Cool briefly on baking sheet until cool enough to handle, about 5 minutes. Pour confectioners' sugar in a shallow plate and roll each cookie in the sugar while still warm.
