Beat 1 1/4 cups sugar and 1 stick butter with a mixer until fluffy. Beat in 1 egg and 1 teaspoon vanilla extract. Add the Super-Chunky Christmas Cookie mix and mix until well combined. Scoop big round cookies (about 2 heaping tablespoons each) onto a baking sheet. Bake at 350 degrees until set, about 10 to 12 minutes. Cool on a rack.
