1 packet unflavored gelatin, sprinkled into 4 tsp cold water left to sit for a few minutes, then heated until dissolved.
1 container lowfat strawberry yogurt
same amount of heavy whipping cream
a tablespoonful or so of sugar
whip these ingredients together until thickened but not stiff with an electric mixer. put the mixer on 'high' then slowly drizzle the melted gelatin into the yogurt mix until well incorporated.
transfer into one of those ziplock type storage bags and refrigerate. it will set in about ten minutes. cut a small corner off of one end of the bag and squeeze the whipped yogurt onto the top of a cooled cupcake.
