Preheat oven to 175°C (350°F). Line a muffin tin with cupcake liners. Prepare yellow cake batter according to package instructions, stirring in sprinkles if desired. Spoon 1 tablespoon of batter into each liner to cover the bottom. Bake for 15 minutes, or until the tops spring back when lightly pressed. Cool completely in the muffin tin.
