Preheat oven to 350 degrees F. Spray 24 medium muffin cups with baking spray. Do NOT use cupcake liners. Prepare cake mix according to package directions. Spoon batter evenly into prepared muffin cups. Bake according to package directions.
Cool cupcakes in pan 5 minutes. Remove from pan and cool completely on wire rack.
Assemble selected toppings and sprinkles, if desired. When ready to serve, fill each cupcake to be eaten immediately with Reddi-wip according to the Cook's Tips. Immediately 'frost' with a topping and 'sprinkle' if desired. Serve immediately.
To fill cupcakes, shake Reddi-wip can. Turn can completely upside down, insert tip into bottom of cupcake and press nozzle sideways to gently fill without cracking cupcake. (Don't worry -- 'blow outs' are tasty too!) Cupcakes may be baked the day before. Store between sheets of parchment paper in an airtight container. Fill and enjoy as desired.
