One day in advance, cut out fondant shapes. Download the PDF for the Splat template and print it. Determine the shapes you want to use to decorate the cupcakes.
Knead 1/8 teaspoon Tylose Powder into each 4 oz. package of colored fondant. Roll out yellow, red and blue fondant to 1/16 inch thickness (keep unused fondant covered with plastic wrap to prevent drying). Using "A" round cutter, cut out yellow, red and blue circles. Use a fine-edge knife and template to cut out the desired splats, stars, and masks in yellow, red and blue.
Use alphabet cut-outs to create "POW" and "ZAP" letters as desired in yellow, red, and blue.
