Bake Cupcakes: Preheat the oven to 350°F. Line a muffin tin with cupcake liners. Prepare the Devil’s food cake batter according to the package directions. Fill each liner about two-thirds full and bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean. Let cupcakes cool completely before decorating.
1 box Devil’s food cake mix
Make Frosting: In a large mixing bowl, beat the softened butter and cream cheese together with a mixer until smooth and fluffy. Gradually add the powdered sugar, one cup at a time, mixing until creamy and spreadable. Beat in the vanilla extract until well combined.
½ cup 1 stick unsalted butter, softened, 16 ounces 2 packages cream cheese, softened, 3 cups powdered sugar, 1 teaspoon vanilla extract
Color the Frosting: Scoop about one-third of the frosting into a smaller bowl and set aside for the white trim. Add red food coloring to the remaining two-thirds of frosting and mix until you reach a bright red color.

Decorate the Cupcakes: Fill a piping bag fitted with a large round tip with the red frosting. Pipe tall, swirly cones on top of each cupcake to resemble Santa hats. Lightly sprinkle the red sanding sugar over the hats for a sparkly effect.
2 tablespoons red sanding sugar
Add the White Trim: Fill another piping bag fitted with a small star tip with the white frosting. Pipe a ring of white frosting around the base of each red hat to form the fur trim, then add a small swirl on top for the pom-pom.
Serve and Enjoy: Admire your adorable creations before they disappear in seconds. These cupcakes are cute enough for Santa, but good luck saving him one.
