Line a large baking sheet with parchment paper or a silicone baking mat and set aside.
In a large mixing bowl, combine the cake mix, oil, eggs, and vanilla and stir by hand until well mixed. Set the bowl in the refrigerator to chill for 30 minutes.
Preheat the oven temperature to 350 degrees Fahrenheit. Remove the bowl from the refrigerator and scoop the dough into medium-sized balls and place onto the prepared baking sheet. Leave about 2 inches between each dough ball. Gently press the tops of the balls to flatten slightly.
Bake for 8-10 minutes, until the cookies are just set. Do not overbake. Allow your snowman cookies to cool on the sheet pan for 5 minutes, then transfer to a wire rack. Make sure your cookies are completely cooled before adding the frosting.
To make the frosting, add the butter to a medium sized bowl and beat with an electric mixer until light and fluffy, about one minute. Add the powdered sugar, vanilla, and 2 to 3 tablespoons of milk and beat until smooth. Using a butter knife or spatula, frost the cooled cookies with the buttercream frosting.
To make the snowmen, add the black pearl candies for the eyes and mouth. Add a jellybean for the nose. Peel one piece of the Twizzlers Pull’n’Peel and shape it around the top of the snowman’s head. Cut it right where the “ears” would be. Add two round peppermint candies to make the rest of the earmuffs.
To make the snow-women, add the black pearl candies for the eyes and mouth. Add a jellybean for the nose. Add one or two bows and additional pink/purple jumbo sprinkles on the top and sides of the foreheads. Serve and enjoy!
