To make the cupcakes, preheat oven to 350-degrees.
Prepare boxed cake mix
Spoon into lined cupcake pan.
Bake for 30-minutes or until a toothpick comes out clean.
Cool cupcakes completely before decorating.
Break off one quarter-sized portion of marshmallow fondant.
With 10-15 drops of black GEL food coloring, work that into this smaller portion of marshmallow fondant. This needs to be black, so if you need more food coloring, add more. If the fondant feels too wet, put it in the freezer for 10 minutes. Set aside.
Break off one dime-sized portion of the white marshmallow fondant.
With this tiny portion of fondant, work in 5 drops of orange GEL food coloring. Set aside.
Break the white fondant up into 12 equal-sized portions.
Further break-up each of these 12 portions into 3 pieces each (1 is about half the amount and the other two being ¼ of the full portion).
Roll each of the now 36 portions into balls.
Stack one each of the smaller balls on top of the larger balls, laying flat on your wax paper to keep them steady while you decorate your Olafs.
Shape the remaining small balls into a narrow ball with one wider end.
Place these oddly shaped smaller balls on top of the other small ball. You should have 3 balls together (like a snowman)
Using a spoon, press down on the top half of each of the oddly shaped balls, forming Olaf’s face.
Press a candy eyeball on each side of Olaf’s face.
Using the black marshmallow fondant, pull off a very small portion and roll it in your hand to form a very small cylinder. Place one cylinder on top of each of Olaf’s eyes to form eyebrows.
Using your fingernail or a spoon, press into the front of Olaf’s face to form a smile.
Using the black marshmallow fondant, pull of very small portions--three per Olaf--and roll them into tiny balls. Place those balls on his torso, two on the bottom ball and one on the center.
With the orange marshmallow fondant, separate it into 12 very tiny portions and roll them into cones. Place one cone each on Olaf’s face below and between the eyes.
Place all the Olafs in the refrigerator until you’re ready to put them on the cupcakes.
With your largest decorating tip, press into the top of the cupcake off-center, creating a well. Save hole tops.
Place 1 tablespoon of white sanding sugar sprinkles inside the well in the cupcake.
Replace the top on each cupcake.
Mix 2-5 drops of blue food coloring into your vanilla frosting, stirring until the color is consistent.
Place star tip in piping bag and fill with frosting.
Frost each cupcake in a swirl, turning the piping bag as you pipe.
Place one Olaf on top of each cupcake.
Serve and Enjoy!
