In a small bowl, whip the whipping cream until stiff peaks form. Add the low fat vanilla yogurt and butter emulsion, stirring until thoroughly mix. Shake a few sprinkles into each of the molds and cover with the yogurt mixture (adding the sprinkles to the whole mixture may cause the colors from the sprinkles to run, depending on the kind of sprinkles you're using).
Put the molds into the freeze and allow to set overnight, or for at least 5-6 hours.
Remove the popsicles from the molds, drizzle with a teaspoon or two of melted pink candy melts, and garnish with more sprinkles.
