Prepare the gelatin layers according to package directions, using slightly less water for a firmer set. Chill in the refrigerator until firm.

Dice the gelatin layers into uniform cubes and transfer them to a baking dish.

In a saucepan, heat water or chosen milk alternative, dissolve the natural sweetener, and mix in the remaining milk.

Bloom gelatin in cold water, then stir it into the warm milk mixture until dissolved.

Combine the milk mixture with the gelatin cubes and fold in fresh fruit. Pour into molds.

Chill until completely set, at least 4-6 hours or overnight.

Cut into desired shapes and serve chilled.
