To make the frosting, place the butter into a mixing bowl and use a stand or hand mixer to beat on high speed for 2-3 minutes until pale and fluffy

Add powdered sugar half a cup at a time, beating well after each addition.

Add heavy cream one tablespoon at a time and beat in the vanilla extract to combine. (See Note 1)

Scoop ¾ cup white frosting into a large piping bag. Set it aside.

Mix a few drops of brown food coloring gel into the bowl of remaining frosting and beat until you reach a light shade of brown. Scoop the brown frosting into another large piping bag.

Use a 9" x 13" rimmed baking sheet as your frosting board, and pipe the outline of Mickey Mouse's head in the center. (See Note 2). Add the remaining frosting to the inside of the outline and use an offset spatula to spread it into an even layer.

Use the white frosting to pipe an outline of "icing drips" over the top of Mickey's head and ears. Fill in and spread into an even layer. Add a sprinkle of Christmas sprinkles to the white frosting.

Using the chocolate premade frosting, pipe Mickey's eyes, nose, and mouth onto Mickey's head. Use the red frosting to pipe rosy cheeks on either side of his mouth. (See Note 3)

Fill the tray with your desired selection of sweet dippers. Serve and enjoy!
