Make the cupcakes in the flavor you want them to be.

While the cupcakes are cooling make your buttercream frosting.

Color your buttercream frosting yellow with yellow gel food coloring.

Place your star into your pastry bag and fill it up with your yellow frosting. Pipe a swirl of frosting onto each of your cupcakes.

Dye 3/4 of the fondant black and 1/4 the fondant red.

Spread out a small amount of powder sugar onto your work surface. Break the black fondant into 24 small pieces and roll them into 1/3 inch ear shape pieces.

Break off 12 pieces of black fondant. Roll them into 1/3 inch oval pieces for Pluto nose.

Break off 12 pieces of red fondant. Roll them into 1/3 inch tongue shaped pieces.

Press two ears into the sides of the frosting. Press the nose into the front of the cupcake and the tongue right underneath the nose. Repeat with each cupcake.
