Pour enough white cranberry juice into your popsicle mold to cover about 2/3 of the container. Put in the freezer for 20-30 minutes.
Drop in 3-4 raspberries per popsicle and push in gently with a popsicle stick. Freeze for an additional 20-30 minutes.
Blend the frozen raspberries with the raspberry juice or raspberry lemonade until smooth. Spoon into the popsicle molds to fill to the top.
Press a popsicle stick into each mold. Freeze for an additional 3-4 hours or overnight until firmly frozen before serving.
