In a large microwave-safe bowl, microwave the butter for 30-60 seconds, until melted. Add the marshmallows, mix to combine, then microwave for 1 to 1 ½ minutes, stopping halfway to stir. Heat until melted and smooth when stirred. Add the vanilla extract and a couple drops of pink food coloring and stir to fully combine.

Add the rice Krispies 2 cups at a time, until they are evenly coated in the marshmallow mixture.

Cover your work surface with plastic wrap. Spray the plastic wrap lightly with cooking spray. Scoop the rice Krispies onto the sheet of plastic wrap. Then spray your hands with cooking spray and shape it into a football.

Use a food-safe paintbrush to brush the edible glitter over the entire surface of the football. Then place the football in the fridge until it firms up, about 30 minutes.

Place the buttercream into a piping bag fitted with a medium-sized, flat piping tip. Pipe the stripes and stitching onto the football, then slice and serve!
